Hey Insane Curiosity Squad! If you liked the video, we would love for you to share it with your friends or on other social networks like Facebook, Reddit, Instagram, TikTok and Twitter, etc... (Since the algorithm is not cooperating in showing us to the public 😅). In just 30 seconds, you will greatly help our Channel to grow and improve future contents. A big thank you from all of us.
I don't think you fully understood the video. It's not about technology, it's about physics. Even IF you could travel 90% the speed of light, it still wouldn't be possible. Do you even understand physics well enough? The only thing that would make this possible is the be able to travel much faster than the speed of light and not even doing it by travelling through the medium of interstellar space. Technology? Basically what you want is faster than light travel and you'd have to be an idiot to say such a thing is possible. No "worm holes" are not a thing, they are purely theoretical.
Not completely. We can do it with Newtonian physics. We need fusion power though but we can see that's happening in the sun so that isn't a theoretical possibility it's real.
@@arnolddooley5919 No one will ever be able to tell you what they themselves fail to understand.. If they operated from a position of truth, you would know about it..
that's right it's not just about speed, everything human build that we use in all aspect of our daily lives are not designed to last more than few years. This is what those scienfiction films always fail to address. You can invent some kind of hibernation for 200 years to get to the next habitable planet on a spaceship. But that spaceship cannot take a break, it is working hard everyday to stay functional. So far no human technology can make simple computer, power supply, circuitry that can last even decades without total replacement. Just look at the ISS, or any any human made space object now, without constant maintenance they all break down completely in just few years or months even.
That would be 10% average. To get the average, you need to accelerate well past the average, then decelerate at the other end (assuming you want to stop to have a look around). Accelerating a mass requires energy, and the mass increases with velocity. An enormous amount of energy is required to get there in a hurry.
Remember that time goes slower the faster you move, according to Einstein. So it may be possible that it is 43 years, for the dude in the shuttle it isnt.
@@kamikazekrush3758 A grain of sand at the speed of light would wreck a spacecraft. At that speed even individual hydrogen atoms in interstellar space becomes an issue.
When first we crossed the ocean we did it in small wooden boats, then we learned to make bigger strong boats that were powered by wind and carried more people and we found steam power and then even bigger ships of iron and steal and now we dont even need ship as we can fly accross the oceans in a few hours anytime we choose in planes... Nothing is impossible for ever... thats what makes humans great!
You are failing to take into account the distances involved here........believe it or not, no matter how great you think humans are,........the universe is REALLY BIG........and human beings are REALLY SMALL.........twenty thousand years from now, someone or something will examine our historical record and say.........can you believe that once upon a time, a large number of seemingly intelligent beings, actually elected DONALD TRUMP to be their leader.....?????????????
@@davidglemboski258 I cant deny humans of our time are small minded and limited.... yet compared to those who lived 15,000 years ago we are clise to gods... maybe it will take another 15,000 years before we have grown enough to take that next big step but we will take it, if we don't wipe ourselves out first!
I mean I get it to have low expectations especially with current technology and political issues. I mean survival’s sake the planet will face resource limits then we might explore space or other solutions to accommodate those resources. After that then new tools and technology will be made or discovered to be faster like cpu chips to reach the stars or whatever.
FINALLY , someone had the balls to say it and back it up with science !!!!! If we as humans continue to in fight over ideologies and political leanings. we sure as hell aren't exploring space anytime soon.
The financial and scientific efforts needed to travel to other solar systems is better spent on saving Earth from the human effects on climate, pollution, over-population and social conflicts.
"When a distinguished but elderly scientist states that something is possible, he is almost always right. When he states that something is impossible, he is very probably wrong." - Arrthur C. Clarke
Exactly, that's why all our electric power and our cars and airplanes are fueled by perpetual motion machines instead of those old fashioned methods that require fuel.
@@medexamtoolscom Ok, but you didn't discredit his point thought: two days ago it was impossible to travel faster than on horseback, yesterday it was impossible to travel faster than on a train, today is impossible to travel faster than on an airplane... Tomorrow? Maybe tomorrow will be impossible to travel faster than 1% the speed of light.

@@VisiblyPinkUnicorn The obvious difference that for some weird unimaginable reason you are ignoring is that there never was a law of physics that said you cannot go faster than horseback.
Just because we currently don't know how to visit other stars, doesn't mean there isn't a way to do it. It simply means that WE DON'T KNOW of a way to do it. Humans are constantly learning, and given a little time we will figure out a way.
We know nothing. We only know about 5% of what there is to know. Dark Matter (22%) and Dark Energy (71.4%) surround us, yet we have no idea what they are. We SO don't know that we just call whatever it is, "dark." Maybe we just need some more time to learn as we're just infants yet...
I'm guessing you have no idea what the Fermi paradox is. The reason why there are a group of people who have a bias toward interstellar travel not being viable at all, is because that opens the possibility more that we are not alone in this galaxy (as in there are other advanced civilization in this galaxy). These people are so biased toward the idea of not being alone in this galaxy, that they come up with excuses like this. If interstellar travel IS possible, then that means we are alone (in this galaxy). This is one of many "excuses" for why the galaxy hasn't been fully colonized, and overflowing, by another civilization/s. Such excuses are called "The Great Filter". I.e. "something is keeping spacefaring civilizations isolated from each other". Interstellar travel being unstainable is such a "Great Filter", among many other hypothesized possible Great Filters. You have to choose one, because statistically it's exceedingly unlikely for both to be true. Either we are alone in this galaxy, or we are not alone but merely isolated because interstellar is not viable. I personally agree with you....we are alone in this galaxy...and interstellar travel is inevitable. eventually, in a relative blink of an eye, we will colonize this entire galaxy. And if at least one another civilization existed before us, they would have done the same by now. In just 3000 years, if our energy needs continue increasing as is, not even the entire energy of our sun will be enough...a million years is like a split second compared to the age of the galaxy. Imagine a civilization that came a few split seconds before us...the galaxy would be entirely covered by them. Unless interstellar travel is something that would prevent that.....
@@tylerdurden3722 You are assuming a lot of things which are questionable. First, you assumed we are somewhat the youngest civilization. What if we are not? And actually one of the oldest? It means that technology hasn't been discovered. Second, Interstellar travel to nearest star vs. distant or other galaxies. There's a big difference in that sentence right there. Interstellar travel only means "other stars" which can be a nearby star. Many other questions exist. What if other civilizations are just too far and their nearest star is all they can travel to? At least by their present technology? The same with us and our future technology. Also, you are assuming again that other civilizations should have been more advanced and would have already travelled in out star. You are also assuming our understanding of physics as of 2024 is already fully understood which is actually very far from the truth. Are you sure our technology and understanding of physics today will be the same 10,000 years from now? I don't think so.
the frustrating thing about lightning speed is that it is still frustratingly slow compared to the size of our galaxy or others, if we attained the possibility to travel at lightning speed we would still be like a snail trying to travel around the earth's circumference
lol. I’m afraid it would be a lot worse than that. The snail would slither a thousand circles around the world before we made even one light speed trip around the Milky Way.
for starters we could very well settle for something like 0,3 of the speed of light . more than 10 stars are within 10,5 ly away from us . which means it would be possible to make a trip to them . trip to alpha centauri would only take circa 14 years at 0,3 speed of light . and engines 0,1-0,3 of the speed of light are already debatable (or at least possible in theory) . we don´t need to colonize the entire galaxy any time soon , we just need to build good enough engine to get us out of this rock and to colonize at least closest star system , that way we don´t end up being wiped out by a single catastrophic event . from there we can further develop our technology , we will have literally hundreds of thousands of years to improve once we are no longer just a one planet species .
@@tracedog27 Yes, you are right, but you have to consider time dilation. When you travel at the speed of light, time seems to stop from your perspective. So, if you want to go to Alpha Centauri, which is around 4.3 light-years away, the trip would only take a few days from your point of view as a traveler
My grandma just passed at 95. She told me jets used to be in books and people would scoff at the absurdity of travelling at the speed of sound. It we make it, say 1,000 more years who knows.
@@alen380 what if you were able to harness enough energy to create some type of magnetic field, creating a pocket inside an anomaly that is used for travel?.
You know how a dolphin rides the wake of ships. Right in the pocket, an eddy if you will. Can we generate something that folds space like the bow of a ship and ride the pocket as well?
@@praxis6172 I guess that what you are saying is related to a future IV or V type civilisation and it is probable in a distant future, we humans have made a huge step forward in technology in the past 100 years so I could agree with your argument, but still by the time humans do that both you and me will be long gone hehe
I am aware of how often in history someone has said that a given event, situation, etc. was impossible. Further, I will admit that it appears, by what you have said, that interstellar travel at a reasonable rate is impossible. That being said I firmly believe that time will prove you wrong and that we or someone else will indeed travel between the stars.
@@MrGottaQuestion what physics are you referring to? With computer technology and hibernation, we could travel to the nearest stars. The question is how safe we need it to be. Physics absolutely doesn't hinder us here. It just takes time. Building large enough ships we could slowly accelerate a ship to a fraction of light speed and then start deceleration half way there. Getting to the nearest star could probably be done in a century or so. There is no fundamental physics barrier about space travel, what so ever. If there were, the universe wouldn't be teeming with solar systems and galaxies like it is. The video straight up conflates "interstellar travel" with "I took a trip to Proxima Centauri last spring". That is not what anyone mean by interstellar travel.
I think you've won the argument and also sided with my theory. if we ever do reach another star system my guess is that it'll be on an at least moon sized, if not planet sized sphere that we somehow stear like a boat.
I suppose that's true..... BUT.... you'd better hope the solar system doesn't ARRIVE at another star in this journey, because that would be rather bad news for any life in the solar system.
according to guy who made the video yes. But I would say, probably everybody is expanding their reach, at 99.999999% the speed of light, but they're taking it slow. A combination of that and SETI is simply not sensitive enough to draw any conclusions yet. They would have to be able to pick up accidental signals such as weather radar on another planet.
"Doesn't this also make it unlikely that any aliens will ever visit us?" About 11 million aliens have visited the United States and most of them are still here.
Not Aliens, but Alien AI or hybrid Aliens. It's a question of time until we become hybrid beings with a bunch of artificial organs in our bodies that will expand our life expectancy and intelligence.
There was a lot of people who said we'd never be able to fly either, we've made it so far in the last 120 years, it's insane to think we'll never leave our rock lol
@@jamessullivan4391 People, not birds, learn to read, and yes plenty of people said that, infact a journalist in new York times wrote just weeks before the Wrightbrothers actually managed to fly that man would never fly, atleast not for between 1 to 10 million years.
@@wiseomg Did you ever see Planet of the Apes? Charlton Heston proved flight to the apes by making a paper airplane and throwing it. Do you honestly think people of a thousand years ago and even 10,000 years ago didn’t simply understand the intuitive physics of watching insects a birds and realized that your lift potential from wings, let’s say, plus speed must compete against your weight or gravity? Shit, I was five years old and tried it with “home made” wings and realized I was just too damn heavy. But I understood at that tender age that there was no barrier or law of physics preventing me or animals around me were doing it. It was just a flaw in my design. I needed counteracting energy to the force of gravity. You cannot honestly believe a journalist who wrote an article once and assume the great thinkers of Ancient Rome, China, India, Egypt or Greece didn’t contemplate how to overcome the struggles while arrows and rocks were slinging everywhere in warfare and motherfucking birds were doing it too. It was only a question of engineering. So the ancients figured out Pyramids, aqueducts, gunpowder, geometry and that the earth is not flat but no, no flight is obviously not possible. Pythagorus and Euclid could not conceive of such a thing.Hot air put into a confined space, like a ballon delivers lift and sufficient force to counteract gravity. I once heard from a journalist that I need to wear two masks while driving in my car alone to protect me from CoVid. Uh… okay. I would go with science and simply say that flight was never defying the laws of physics, like saying going beyond the speed of light/causality, and was a simple matter of achieving the engineering skills to produce it. Read “the Flight of Icarus” in Ancient Greek mythology and see that a boy with feathers held together by wax, but he flew to close to the Sun and they melted, is an achievement of understanding that “we simply cannot do it yet,” not that it is impossible unless you hold religious views that somehow banned it. My own faith never “banned” it. So to close, just use a little common sense here.
@@jamessullivan4391 You said "Actually, no one ever said that. From day one, man has watched birds fly." That mankind trough the ages watched birds fly have nothing to do with the comment you were first answering, wich was There was a lot of people who said we (mankind) would never be able to fly and they ofc were wrong, i even pointed out a spesific "brainiac from the new york times saying this in 1903 only a few weeks before the Wright brothers made the first flight, look it up.
Ahh, okay. Got it now. Mispellings and wrong prognostications have lead me to believe that you don't know shit. No offense, I have to leave this thread to argue with smarter people. Take care.
This just means you can't make the well connected galactic empires you see in a lot of sci fi. It doesn't mean groups of us can't just move through the universe slowly.
@@kvarnerinfoTV Yes, Alcubierre demonstrated there's nothing preventing the warping of space to achieve faster-than-light travel. The problem is the energy required to do it would be something on the order of what you'd get from a black hole. So, until we're able to create artificial black holes, harness their energy, and use them to power an Alcubierre Drive, we're not going anywhere; or at least not going anywhere very quickly. If we're serious about colonizing distant worlds outside our solar system in the near-term, it's going to have to rely on generation ships or some form of cryosleep / hibernation / suspended animation.
@@JohnDoe-zl6qw energy requirements for a alcubierre drive are being smallaer and snaller with every new paper. I am quite positive that in next few decades we will be able to lower it to acceptable levels. Also we will soon have tech to reach near light speeds so closest stars will be far closer...
@@kvarnerinfoTV The power requirements may be decreasing, but reading deeper you come to realize the power requirements are still (A) astronomical relative to what we can produce today and (B) rely on something that is currently being called "negative energy". With regard to (A) the original calculations called for a ball of antimatter the size of Jupiter to power the Alcubierre Drive. That's since been revised down to one the size of the Voyager 1 spacecraft. Sounds reasonable, right? Until you realize the only anti-matter we've been able to create has been in particle accelerators/colliders. In 2010 the Large Hadron Collider created a total of 38 anti-hydrogen atoms worth which lasted 0.166 seconds. More has been produced since, but still in equally infinitesimally tiny quantities. We're a long way off from producing tons of anti-matter that will remain stable, let alone that could be safely stored and transported to be used aboard a starship. Also, there's no such thing as a free lunch. It takes energy to power a particle accelerator/collider. You don't get to create energy out of nothing using such a device. The energy you wish to store in anti-matter has to be energy you put into the accelerator/collider. The amount of energy stored in a Voyager 1-sized ball of anti-matter exceeds the total energy output of the entire human race the world over at current production levels. So what do you propose? We all stop using electricity and burning coal, natural gas, and oil for a year so a theoretical warp drive can have enough fuel for a test flight? Then there's the economic burden. It's estimated 1 gram of anti-matter has been produced in total by all experiments to date that have attempted to do so...at a cost of one trillion dollars. At a launch weight of 1,797 lbs, a Voyager 1-sized ball of anti-matter would cost $815,105,542,800,000,000 (that's 815 _quadrillion_ dollars). Where's that money coming from? With regard to (B), we have no direct evidence for "negative energy" yet. It may not even exist. Alternately, it may turn out to have ties to Dark Energy or Zero-Point Energy. Regardless, we're still a long way off from even being to able to construct an experiment to witness it let alone harness it (if it even exists). I'm not against the advancement of scientific knowledge and technology and would very much like to see us achieve some form of propulsion to take us to the stars. However, dreams must be grounded in reality if you ever want to achieve them. There's far too much dreaming and not enough grounding when it comes to these discussions, with a flippant disregard for the overwhelming technical, engineering, social, and political challenges it presents. We are not even remotely close to being able to build a working Alcubierre Drive in our lifetimes. I'm not saying don't pursue it; I'm simply cautioning one needs temper their expectations and to be more realistic with regard to the timelines involved.
As they say, “never say never” because you never know! Given what we’ve learned in the last hundred years or two, and that things are accelerating, imagine (if we manage not to blow up the planet to oblivion) what currently unimaginable things we might have discovered in the next hundred years or two. This video is perfectly sensible, but it should add “in the current state of our knowledge”. Who, in 1850, could have imagined the Internet or the GPS? Not even Jules Verne did. Also, who says we need to explore the galaxies with our very inadequte biological bodies? Maybe that will happen only once we’ve transformed ourselves into some kind of electromagnetic entity or uploaded ourselves into one? There are probably more surprises lying in wait for us than we have ever experienced in our past history. Hopefully not total self-obliteration though…
Tell me something: If we do an experiment today to measure the weight of a cubic meter of iron and the experiment tells us that a cubic meter of iron weighs 7,873 kilograms, do you think that in the future a new theory of physis will be developed such that when we weigh a cubic meter of iron suddenly it weighs 20,000 kilograms instead of 7,873 kilograms?
There are many possibilities, of course. But the video is making a general statement based on the likelihood of those things happening before we are obliterated by either ourselves, a virus or local catastrophe, or some outside force like a meteor is quite low.
I think, that the main problem is the definition of "we". If we widen it to our creations like robots and AI, maybe even our minds recreated as AI, then all those arguments are not applicable. 400 years at 0,1% c to Proxima? For an artificial intelligence it is absolutely no problem. For a digitalised human mind it could be Star-Trek or Star Wars or whatever experience it chooses. All you need to do is to change the time perception. With years passing like secunds, it would be just a five minute trip (I would rather choose an hour as a year to have a chance to read some book and explore my virtual Millenium Falcon at least ;)
Its not just about getting up to speed and the risk of possibly hitting something its also about trying to stop once you get there. You cant just stop in space going that fast.
Just build the spacecraft like a rocket with several rotating deflectors and pulverizers at the front. The diameter of the cylindrical spacecraft should be as small as possible. The spacecraft can be made longer. Build them like a pencil. If one tip breaks, sharpen it again. The payload should be near the end of the pencil.
@@marajevomanash a space ship traveling half the speed of light that hit a 1 gram rock would create an explosion bigger than any nuclear bomb, there would be no pencil to sharpen
thats why a space ship that could rip open worm holes (we dont even know if thats possible) would be ideal, you dont have to go all that fast when you have a portal from one end of somewhere to another so that would take care of that issue but thats probably not possible anyways, just cool science fiction
There‘s a small mistake when the number for the speed of light is mentioned the first time. It is not 299 million km per second but 299 thousand km per second (or 299 million meters!) Very good video!
The true speed of the light through the vacuum is 299,792,458 meters per second. 😂 In One pico second, the light travels 1/3 of millimeter. Fiber optic transmission technician
Artificial gravity is easy, you just get a large cylinder and spin it, and shielding is pretty easy too, we can already shield against everything that we need to, it's just expensive in mass to get all that shielding on things that need to be launched off earth
In a way, it's comforting to know that we'll be safe from malicious aliens who might show up at our doorstep one day. On the other hand, knowing that there most certainly is other intelligent life out there but we'll never meet due to the vast distances involved, is quite sad.
How do YOU know that? We could have aliens living amongst us right now. think about a civilization out there somewhere that has a BILLION years of evolution on us. Do you actually think they are as STUPID as we are? Yeah we really haven't been around for very long at all... not compared to cosmic time. Also think about the odds of us as a civilization living at the SAME TIME as another civilization located wherever. The odds of multiple civilizations LIVING AT THE SAME TIME is really tiny. Sure. think we'll be around in a million years? and remember a million years is but a drop in the bucket compared to cosmic time. yeah Earth has been here what, about 4.5B years.. well that's 4,500 M years!
@@grumpyou1138 I didn't assume that a race capable of interstellar travel is malicious. I assumed that some intelligent races are malicious, and of those, some are capable of interstellar travel.
The dilemma that has always confounded me when I think about space travel is one of simple Geography. The information we have (ie, what we see) is old information. The light from astronomical sources we see is old (as much as thousands or millions of years in some instances). Those objects have moved in that time (the galaxy is rotating and space itself is expanding). Flying to Vega, for example, is not like flying to Vegas. Because Vegas is always in the same location. The best we know about Vega is where it was located 25 years ago. Although Vega is “close” and unlikely to have moved much “galactally” in 25 years, the problem is much worse for more distant stars, let alone locations outside our own galaxy. Also, we all know stars go through phases, one of which includes a supernova. Given we are always acting on old info, it is entirely possible we could chart a course to “Star Z” only to find Star Z has exploded in the hundred or thousands of years it took its light to reach us when we charted the voyage. Creating reliable and “dynamic” maps that adjust for historical movement of objects and future movement (during the time it takes to make the journey) strikes me as a daunting proposition in and of itself.
Trajectory to Mars and other astronomical objects is planned based on its location in its orbit around the Sun by the time we get to the destination. It is possible to predict the movement of nearest stars in respect to our own or in respect to the centre of the galaxy, so it should be possible to chart a course, accurately predicting its location by the time we arrive. Even working with old info, we should be able to predict the current state of the star in the present VS. the apparent (X ly in past). Unless there are clear signs of a star going supernova or it being on the other side of the galaxy, 1000 or even 10 000 years is just a blip on astronomical scales so it is unlikely for a star to disappear in that time.
@@ilmarssalna8900 Uh, the light from Mars reaches us in 2 MINUTES.....Yes, we can account for that and predict where it is going to be. You could probably even make assumptions about things with 100s or 1000s of light years away. But You cannot know with any reliability where something is going to be or even if it exists if that light is BILLIONS OF YEARS OLD...
Motions of stars can be predicted just as the motions of the objects in our solar system, assuming you're trying to reach a reasonably close star. If your destination is so far that you're worried your target star having gone supernova by the time you arrive I'd say you've got other problems. :') Conveniently the same laws of physics preventing you from observing the "present" state of a distant object will prevent you from reaching it...
Flying, just as flying really fast don't violate the laws of physics. We are never going interstellar, not as organic beings. Unless our consciousness can be transferred to synthetic bodies, we as a species are doomed to stay right where we are.
We never though we could speak into some plastic phone and talk to somebody on the other side of the world. 200 years ago it would be called magic, that is beyond human understanding.
That's a bold statement, but I have to agree it is a remote possibility. To date, moving any mass beyond the speed of light is impossible. Even accelerating to 1/2 the speed of light would kill everyone on board. Even at 0.1C it would take 40 years to get to the nearest star. The whole "folding space" thing is just hypothesis. Gravity can bend space but even if we could build some kind of gravity generator the power required would dwarf the current global output.
If it took 40 years to reach the nearest star, and we sent colonists to the Proxima Centauri system in 2050, then we'd have humans living in another solar system by 2090. That's... not very long compared to the length of human history.
@@adammclaughlin845 While there's without doubt a sheer infinite number of Earth-like planets or moons sprinkled allover the observable part of the universe, the chances that one of those happens to orbit around one of the closest 1000 stars is probably quite small.. and almost certainly there's none in the A Centauri system. So this would most likely be a very educational one-way trip much better done with unmanned robotic probes. (Not even talking about the energy/propellant problem, sufficient means of life support, high energetic cosmic radiation and collisions with cosmic molecules/dust/micrometeorites...)
Not a remote possibility, but the most likely scenario (says someone who studied astrophysics). It's not just not possible to move any mass beyond the speed of light "to date", we have not observe this happening ever, even in the most energetic cosmic particle accelerators observed (active galactic nuclei, GRBs, supernovae), and if it were possible at all you'd think that those objects, which output energies a trillion times higher than the largest particle accelerators on Earth, would be able to do it. Even completely massless particles such as photons (eg. light) travel only with "c", not faster. So if it were possible to somehow exceed this fundamental speed limit, it's not something that could be achieved with the help of any of the known types of matter or force fields - and if there are particles that indeed do move faster than 'c', they have yet to be found, and guess what - your or my protons/neutrons/electrons etc forming carbon, oxygen, hydrogen etc. atoms of organic or inorganic matter as we know it are definitely not among them...
We started on our belly, then we walked on 4, then we stood & walked on two, then we ran. The wheel, cart, wagon, train, car, then we flew, and flew faster and faster until we flew so fast that we made it to the moon & back. The time it took for humans to go from belly to moon is but a moment in time kept by our universal clock. Never?
Yeah humans have practically made it a job proving the impossible possible. People have been doing the impossible for thousands of years lol just a matter of time
@@aegisurjagas2298 the laws of physics are like anything we’ve learned….. it easily changes with new knowledge. We literally see things behaving in ways we can’t explain.

So especially at a time when our actual government has confirmed recording uap objects breaking the laws of physics lol not saying they are aliens, just saying they are literally recording objects breaking the laws of physics as we know them in multiple independent systems at the same time.

I like what your saying and I agree. Right now these are barriers we cannot break and in time I'm almost certain we will. And when we do it will be a long time before we realize it worked meaning interstellar travel. We will naturally not start our anywhere near a tenth of speed of light and even at the speed of light from our prospective hear on earth well we'll not know if the trip worked until whatever agreed upon distance in the test. Either way for the folks back here on earth will need patience

@@jonathangleason72 I agree, we will never know what may happen way in the future, but it's unlikely we will be around for a long time anyway. It's the law of physics that you can't travel as fast or faster than the speed of light.

With our fastest space craft, it would take 450 million years to get there, better take a cut lunch with you.
I always hated that cliche, "Believe me" when anyone is talking about a nebulous subject such as interstellar space travel. To me it quite arrogant and even narrow minded to think that we will never travel to the stars because that belief is based on the very limited understanding we now have of the universe and the fundamental physics that make it go. I set no limitations on human abilities. However our greatest threat to not reaching the distant stars is our capacity for self destruction. The world is in a very precarious position right now and many research scientists feel that are already well into a Sixth Extinction event. But assuming we can overcome our many short comings we may in future centuries discover physics we can't imagine now. It was with great naivete that at the turn of the 18th to 19th century many physicists thought that was nothing new to discover in physics. In the same way I find it short sighted that people think that we will never travel to the stars. And when people reject the idea of traveling to the stars it is always with the same single minded focus that physics says it is impossible to travel at the speed of light for the reasons given in this video. This narrow minded thinking prevents those same people to imagine an alternative mode of travel through the universe that does not rely on traveling anywhere near the speed of light. But we are perhaps hundreds of years away from discovering the physics that could make that possible and we must learn to overcome our differences IF we might possibly live that long. There are of course the natural threats beyond our own capacity for self destruction!! Despite these many obstacles to realizing deep space travel many of us will continue to dream of what could become our future, distant though it would be. Edit In the 3rd paragraph I meant to say 19th and 20th century.
Thank you for your comment. At one point man didn't know what fire was. Then he discovered the wheel. Then many eons later he learned to master the skies. It's my profound belief we will become an interstellar species. Once we reach that level of advancement there's no stopping us.
Given the shortness of our lives, you are right that this will not happen in any MEANINGFUL WAYS TO US. That is why the answer to Fermi's wonderful question: "Where is everybody?": is that they all stayed home, since they had no choice.
They said that we would never travel the globe, today we have planes that can circle the earth within the hour. Not long ago we produced a nano warp bubble. Which people said would never happen, yet it happened. It is people like you that give humanity the strength to push on, and we are likely on develop warp drive before the end of this century Galactic domination is inevitable. Also the warp bubble stops time dilation and makes the warp process possible. The whole process is rumoured to be able to work on a fission rector….
We can, we just haven't yet. We can't accelerate anything to or past the speed of causality. Even if teleportation is invented, it will be limited to the speed of causality. Even theoretical wormholes reveals this limit in it's math. In other words, it's not possible for the Effect to happen before the Cause. E.g. you can't make the cause and effect of lighting a match happen in reverse order. Moving faster than the Speed of Causality would result in such things. You'll be able to arrive at a destination, before having left your departure point. In fact, if you go fast enough past the speed of light and make a return trip, you'll return before you left.
Buckminster Fuller put it very simply: " We already live on a spaceship." That said let's take care of it rather than spew it with toxins while trying to get to other worlds.
Never is a strong word,. We will never build a plane that can traverse the Atlantic Ocean said by Wilbur Wright 2 years before the first Atlantic crossing 🤞
@Uhavenoright toask such close minded thinking - you act as if we know everything there is to know about everything. Space travel is definitely more complex then atmospheric travel, sure, but thats not to say that its impossible. We barely even scratch the surface of what is known about our reality, space, time, mass etc - the universe is filled with alot of shit we barely even understand and i dare say things we don't even know exist. The answer is out there somewhere and we will find it, eventually
UFO literature seem to point to use of magnetic fields for propulsion and an ability to manipulate space and time to travel at high speeds. Maybe this is something worth exploring.
true people are in this comments don't understand that Stars scale the space in between are INSANE too far away. Is not the same as human scale on earth no matter how advanced technology getting in another solar system is dangerous and is not need it because in our solar system have enough space for trillions of humans to live
As a kid i always imagined space empires and other crazy stuff. As i grew up i realized that it is a waste of energy to try it. So much time to get to one place, communication would be a nightmare. All the alien invadong Earth movies look now ridiculous to me. Why waste so many resources for a war? By the time your planet knows the result of the invasion, your leaders may be dead and theres probably a new party in power or there was a war and people no longer care about you. It is easier to fix all the problems in your planet than to try and invade others, at most i believe we could land of asterpirds or meteors and extract materials from there.
I believe you. Star travel is going to be very very remote in even attempting/doing such a venture. We will be lucky to visit our nearby planets and setup any kind of structures or space stations around them.
So, what you are suggesting for example your cell phone will not change in the next century, I am sorry to break it to you but like cell phone our space ships will improve in the next century and beyond to settle distant areas in our solar system my friend. Another thing no one on our planet is traveling by sailing ships, that kind of travel is so 19th century!
those will be the first steps, followed by others, for hundreds and thousands of years, the key is to survive and "get some eggs out of this one basket".
Star travel is impossible for two main reasons. Majority of stats that has been viewed don't exist anymore and are merely illusions but also that even reveling at the speed of light you'd need millions of human generation to reach the closest star system.
@@douche8980 "even reveling at the speed of light you'd need millions of human generation to reach the closest star system." no. not at all. It is 4.2 ly away. You would need 4.2 years. If you could travel at 10% of light speed you would need 42 years, it's really rather simple.
Don't know who originally quoted this but I'll leave this here: Times are going so fast nowadays that people who say it can't be done are interrupted by people doing it. We will reach the stars, we have to or we die. No better motivation than that.
@@dalethelander3781 Everything l hear about the cosmos tells me, "don't come here". You just have to view say, Anton Petrov's posts to get the flavour of it. People who blandly say men will reach the stars aren't thinking it through. I could write an essay on why they never will but it would take too long. In synopsis we're too puny, distances too great, ambiences too dangerous. In the RUclips videos debunking Elon Musk they showed how his plans to reach Mars don't add up. There are too many unknowns as well.
Agreed & well said. This garbage reminds me of that 1899 Charles Duell quote: "everything that can be invented has been invented." If you think we are incapable of the type of achievement that could lead to interstellar space travel, you've obviously not been paying attention to either the 20th or 21st centuries. Can we do it now? Of course not. In 100 years? Perhaps not. To say that it's impossible in light of all the progress that has been made is both ignorance and pessimism of the highest order. Get off my video feed, noob. lol
I'm an "older" guy (in years, not in life style). Ex-news-guy, and been putting serious study time into Astronomy, especially the long distances between space objects. For one, the alignment of the orbits of earth and Mars get close enough for inter-planet, only every 26 months. This means that the suicide "voyage" to Mars would be just that, a way to become a gamma-ray bombarded "crispy critter". So this voyage, with any humans, would take a minimum of 2-and-a-half to three YEARS. The "space ship" would have to be half the size of big Star Wars flagship/cruiser. It would have to be assembled IN ORBIT of the Earth, a task that would make the Interna'l Space Station seem like a tinker toy in comparrison. And going to any other planet (mainly Jupiter) would be way too far, a round trip of 5 to 6 years minimum. No human will ever go any further away from our Earth's moon, EVER. The cost would be enormous, and we would not learn all that much more than our various space probes have already done. We know what is there, and practically speaking/witting, sending any humans there is a waste of time, effort and money. { : - } ~~
I forgot to include this: A transit through space will not include any fast-travel portal or wormwhole. These are speculative notions, and a part of what is known as "Science Fiction", and not even remotely available. Wishful thinking, that's why Science Fiction is, and just this: A story not able to be regarded as "true" and/or possible.
Yeah the thing everyone forgets because they're so focused on theoretical propulsion systems is the fact that even if we managed to go fast enough that long-distance space travel was on the table, the REAL problem is radiation shielding. Until we solve the very, very, very real problem of figuring out a practical way to keep our astronauts from getting lethal doses of radiation on their trips, we're not going anywhere. Our ISS orbits well within the Earth's magnetic field. But radiation was an extremely serious concern on the trip to the moon, even though it wasn't publicised. An inopportune solar flare or other gamma ray event would have had catastrophic consequences for the Apollo astronauts. We just chose to roll the dice and hope for the best, and it worked out. But longer-distance travel will absolutely not have that luxury. And lightweight, durable, and effective radiation shielding is every bit as difficult a problem as high-speed theoretical propulsion.
@@Dr.TJ_Eckleburg Your explanation of these facts is better than mine, and I appreciate it. So now the challenge is to get people to stop believing in Elon Musk's "solutions" to our mutual problem. He and others are neither scientists, nor pay quality attention to scientists WHO ARE EXPERTS in the field of the risks of inter-planetary "travel".
This vid is ill-named. It should be called "Why We Will Never Travel Faster Than Light." Traveling among the stars is no problem at all, as long as you don't mind the fact that it will take a very, very, LONG time. Many different methods - all perfectly acceptable to the laws of physics - have already been preposed. Suspended animation for the travelers. Generational ships where those that arrive are the descendants of the original crew. If ion drives work, it has been shown that with the constant acceleration you can get to Proxima Centauri in one human lifetime... a one way trip where you won't have much time to accomplish much when you arrive... but we CAN. Even trade is possible with decades long plans run automatically with no communication needed. So many shipments per year of X in exchange for so many shipments per year of Y for the next 100 years or so carried by automated unmanned craft. That works fine with planning and patience. Never travel amongst the stars? I scoff. Of course we will. The only question is how distant in the future this will be as we balance our desire to do it faced with restrictions of physics... which aren't restrictions at all if you think in terms of generations of humans and decades and centuries of implementation. And all this presumes that the average lifetime of humans shall remain as is. If you do some research on aging and proposed methods of its prevention, you will see that surprising progress has been made. In a couple of hundred years the human lifespan may have been greatly increased.
It is almost guaranteed that the life in board any space ship won’t last long as space itself is lethal to life Astronomers found out recently that there are many pockets of space which look empty but are made up of dark clouds with unbearable temperatures and radiation which no life can get thru, the list of dangers in space to any life is endless, there are literally 6 billion way space can and will kill you So yes the video title is right, humans will NEVER travel interstellar but the AI humans make in the future will since they are not vulnerable biological creatures like their creators
On the topic of trade, why would trade even be necessary? There is an unimaginable amount of resources out there, a small colony of 10,000 guys in Bumfuck nowhere system would possess 1000 times more wealth then then entire earth combined does now. Trade would be a novelty, the only meaningful trade would be that of ideas, and ideas can be transmitted at light speed via laser communications
The nearest star system is less than five light years away. We only need to reach 10% of light to get there in less than 50 years. We should be able to send a probe at that speed before the end of the century. Given another hundred years we should be able to scale that technique to human travel. Less than two hundred years is far from "never."
And I would like to add, if we can go to one habitable exoplanet in the galaxy, we should be able to colonize all of them in an exponential process. If we can go to proxima and establish a presence there, we can eventually develop that and turn it in turn into a launchpad to a system under 10 ly from there, etc, etc. With each system we take our capacity to grow increases too. So we get a positive feedback loop of continious growth until the entire milky way is taken. The most interesting number is the average of the minimum distance between habitable planets in the galaxy. Because you are severely hampered if you have to use Mars like rocks in this process compared to habitable planets.
@@dekippiesip exactly! I figure we can at least average 10% of the speed of light at colonizing the galaxy. It's round, and our path will be in both directions around the outside of the galaxy. The inner parts of the galaxy are the most dangerous for life. Multiply the diameter of the galaxy by pi times 10 and you have an approximation of how long it will take to colonize the galaxy. We'll also spread out to many other minor galaxies, and be ready for Andromeda when it gets here. There's one last thing. The problem with habitable exoplanets is they are likely to already have someone or something living there. We may only send scientists if simple life, or trade and diplomatic personnel to those with advanced life. Small planets, moons, and asteroids are the best because they're resource rich, minable, and we don't have to deal with existing life or an existing civilization.
Yep, the problem with this video is it assumes that we need to get to the destination quickly. If we were able to mine resources in space we could theoretically have a multi-generational space ship. Give it whatever time it needs, 100 years, 200 years, ect. However I think if we were able to live in space for a really long time we may not even need a planet and could just live in space. But of course there are benefits to living near a planet system. Additionally the video commented on how we wouldn't be able to established trade routes if the distance too that long to conquer. But there isn't any reason the colonies couldn't be independent from earth and our solar system. Also his proposed solution to the fermi paradox isn't necessarly the correct one.
I think something that could be said about the Fermi paradox is that perhaps there has simply not been enough time in the universe yet for any civilizations to have developed Interstellar travel. Perhaps it has taken this long for the heaviest elements to have been created to allow for technological civilizations in the first place
Maybe. An even bigger problem to me, though, is the highly anthropocentric notion that technology is somehow inevitable. And it's not, as every other organism on earth except humans demonstrates. Orangs have been here as long as we have or longer, yet still no language and no tech. And now that we've spent the last 75 years making absolutely sure that the rest of our rather enormous solar system is utterly sterile the idea of ubiquitous life is starting to seem a bit absurd. It is so sterile in fact that we are now reduced to hallucinating about floating organisms in Venus' atmo, buried organisms on Mars and ones floating in the dark in subsurface oceans on a few icy moons. Not saying that's impossible or not worth examining, just that we were actually thinking a century ago that there were advanced aliens living on Mars. How far the fantasts have fallen! We could see their canals, I tells ya!
Yes. Everyone who thinks there is a paradox because we don't see aliens doesn't understand how far apart everything in the universe is, and how slow the speed of light.
What’s even more scary is that it has taken us 4+ billion years to get to this level now, yet one meteor strike could wipe all that progress away. I think that’s part of why we may never develop anything capable because we would need a massive amount of time coupled with the hope that WE also wouldn’t have destroyed ourselves.
@@ebukaobieri Well, there's eugenics and elitists on earth too. All this doom&gloom stuff I tend to always assume is highly overhyped. Eugenics doesn't happen by itself you know.
We've only developed modern technology in the last 150 years, and we've made some impressive progress in that time. I do agree however in that in order for us to solve the problem of interstellar travel, it'll take probably thousands of years of human development to break through barriers of our understanding of what is possible. But then again, it's not like we haven't done it before. If a modern person were to take some of the technology we have today and travel 500 years into the past, they'd be burned at the stake for sorcery. On the other hand, what if there isn't a way to break the speed of light or to alter space around you to travel FTL? I guess that's always a possibility, that in fact the vastness of space will forever remain something pretty to look at, but not something humanity will achieve. Only time will tell, and no one alive today will be able to answer the question either way.
Or the scientists working on nuclear power ion propulsion or laser sail technology make a practical drive powerful enough to launch hundreds of probes from the moon to adjacent star systems. We may not get there this century, but there's no reason we can't have probes on the way by then. Exploring the galaxy will of course take a lot longer, possibly a million years, but that's not never. Basically we just hop from one star system to the next until we run into friendly aliens to trade with.
@ApplesWithPeanutButter that's why we should start with nuclear powered ion drives and laser sails. It doesn't get us to FTL, but it can get us to the next star system 4 to 5 light years away. We don't need to travel a thousand light years to a star system when there's one less than 5 light years away.
This is an idea that proposes that technological progress must be continuous and infinite. It is a faith that forgets how nothing we have done in the past is remotely like interstellar space travel and physics is not cooperating in this matter. Breaking the sound barrier, or flying or crunching digits with a device are simply not comparable to interstellar travel. We worship tech as we once worshiped fire. Fire has its limits. So does tech. We were supposed to have space colonies by now. We even could. But we don't. There are reasons why.
No offense but you simply don’t understand. Humans mastered the manipulation of basic physical materials and chemical reactions many thousands of years ago. Today’s tech is no more than minutia of the same physical contortions. For us to master near light speed travel is the equivalent of a fetus learning Mandarin while still in the womb.
To put in perspective how little we know only a few decades ago there was sort of a consensus among scientists that we would *never* know if other planets existed orbiting other stars. As of today we have discovered over five thousand. "Never" is too long, all possibilities are open.
Honestly I would be perfectly content with visiting the Moon and colonizing Venus. I once did an original sci fi story about a man who worked with thousands of other people to terraform Venus. However instead of making Venus the same as Earth they instead created an entirely unique environment and biosphere that humans could adapt to over time. If I could be a part of something like that it would be a dream come true.
When the Russian space agency sent a probe to Venus, several decades ago, it took our only known surface pictures of Venus, for about a minute or two or three before the very hot surface of this planet melted this USSR probe. The average temperture of the COLD SIDE of Venus can melt lead.
Well hopefully humanity can adapt to a Venuisian biology fast due to the climate crisis this little blue speck can become another Venus. I don't think that humanity will last another 150 years. No one is willing to give up their gas powered vehicle and the government is not doing enough to combat the environmental problems, we will not find any miracle that will take carbon out of the atmosphere or clean up the environment, sorry to say it but that is a sad fact.
Venus is a poor candidate for colonization. The 90-atmospheres worth of crushing pressure at the surface, carbon dioxide atmosphere, sulfuric acid clouds, and 800-degree Fahrenheit surface temperature are just the tip of the iceberg. The real problem with Venus is the lack of plate tectonics. With no outlet for the planet's internally generated heat through volcanism and subduction fault lines - hallmarks of plate tectonics here on Earth - that heat builds and builds. Eventually the entire surface of Venus, no longer able to contain the heat, turns molten and is completely resurfaced every 500 million years. Over the course of 100 million years it cools enough to re-solidify. Then the cycle starts all over again. Mars is not without its challenges, too, but they are far more easily surmounted than Venus' will ever be.
Ok this is a bit if a misconception, there is rest mass and relativistic mass. The object accelerating doesn't actually gain mass. It gains momentum, a 1kg mass traveling at 1c would have a momentum of 299,792 kg m/s (momentum is p = mv). The error occurs because E=mc^2 is on useful for a mass at rest, not a mass that is in motion, for that you need thfollowing equation. E^2 = m^2c^4 + p^2c^2
I think it's the difference between gravitacional mass and inertial mass that is usually the same in non relativistic scenarios. We can say that its inertial mass has augmented however measuring against gravity will give us the same result. The question is, what do we mean by mass.
These assumptions that we will simply Rocket our way into space are what make it impossible. I have no doubt that trying to propel a craft to near light speed is impossible. But, the math for a warp drive is being worked out, and the more they work on it, the more likely it seems. A warp drive is warping a bubble of space, the ship inside the bubble is not actually moving. So all of the math around relativistic speed does not apply.
@@alphagt62 Yes, the Alcubierre Drive (space warping) has been shown to be feasible; at least theoretically. The problem isn't whether or not space can be warped; all indicators point to it being possible. The issue is the amount of _energy_ required to do it. It's several orders of magnitude beyond what we're currently capable of harnessing/building. Think energy on the scale of a black hole.
There was no mention of "generation" ships where the original crew doesn't reach the destination but their children or grandchildren do. People would be born, live, and die on board the ship never knowing what it's like to set foot on a planet. There are many technical challenges to be over com before any such journey would be attempted, but that's what humans do; explore the unknown. Saying it will NEVER happen is defeatist language. WE may never travel amongst the stars but that doesn't mean a few generations from now, we won't have the technology to do it.
Reading the Stephen Baxter Xeelee Sequence books that deal in part with interstellar travel, and the picture painted isn't a positive one when it comes to generational travel, and for reasons that deal as much with human nature as with the perceived limitations of technology. It certainly won't be Star Trek, or even the relatively more realistic Expanse series. Bummer.
@@edgregory1 it would need to be a global investment. This would come after years of exploration in the solar system showing the profitability of space travel. It of course would be a colony ship that may or may not be profit-based. Not all of our exploring was done for profit, the profit was realized after the fact.
I found it helpful to actually do the calculations myself. Consider a light year to be 5.88 trillion miles away, (Alpha Centauri is 4.27 light years away), divide by the speed you’ll be traveling at, in this case 38,000 mph, divide by 24, then divide by 365.25 and you’ll get 75.37 thousand years. The calculations approaching light speed is beyond my grasp, so I’ll take your word for it. Still, I’m quite amazed at the number of people who want to affirm the possibility of traveling to Alpha Centauri. I think this is quite common, though it flys in the face of math and science. Of course we the living will never know for certain if this is actually a possibility, but I find it strange that there is no sense of human limitations here. And then I strongly question why we would even want to venture this far when our real concerns should be here on earth. I’m wondering if there is an inverse relationship between faith in technology vs faith in our humanity to address the problems we have here. In other words, are we inordinately caught up in the possibility of space travel that we would choose to abandon our responsibilities here on earth?
Apologies for the late reply - the video just showed up in my feed… Why would we want to do this? For the same reason we want to do everything else: to see if we can… humanity is inquisitive by nature. It is why we are (or at least, we believe we are) at the top of the food chain, and the dominant species on our planet. Imagine we discovered that, in less than a decade’s time, a huge object was almost certainly going to impact, and destroy, the Earth, and there is no known way to stop it. Yes, there would be people working on ways to avoid this outcome, but surely this would also be incentive to find a way to get to a new world, or find some way to save everything unique on the planet?* If this does not compel every nation to come together, and work towards a solution, then nothing will, and I guess we don’t deserve to be saved. Perhaps we will never have the incentive to do so. I certainly doubt any real effort would, or should, be made, until we have sorted out all the problems around the world, and we all live in a utopia. Unfortunately, such a goal does not seem to be high on anyone’s list of priorities. Hopefully, wiser, and more intelligent, minds will one day prevail, and we get our collective problems sorted. Then, perhaps, we can turn our attention to the stars. Cheers, * Most likely, we would look to set up a colony on Mars, as it is close (in astronomical terms), and we have already carried out preliminary studies of the planet. We won’t save everyone, or everything, but humankind would survive. Of course, once we were set up there, I suspect we would then start looking for ways to move to more accommodating environs, on other worlds.
yes, it would be even better to find "good for us" uninhabited planets cuz it would be "rude" to move in on inhabited ones, even with lower life forms, but maybe microbes would be an exception, if we don't catch a "severe cold" there! ;D

why so certain when the first human to live to 1000 may already be alive - who is to say how much human lifespans will expand during the next 10, 20 or 30 years. At the rate of our understanding and progress it is reasonable to assume there is indeed a possibility that we will reach the technological capability to extend life expectancy in the near future - the question is how can we manage over-poplation if we do so.
Yes we can. Everything has a limit. People just WANT to believe these things are possible no matter how much the universe and science is telling us it’s not.
This is just wrong. It's E=mc. Not E=mc^2. C-squared is absolute absolute acceleration of the mass. E=mc equals Energy can be neither created nor destroyed, only transformed. Acceleration is what transforms energy. Newton's Laws of Motion. An inertial frame is one in which acceleration comes from an outside force. A non-inertial frame is one in which the object is accelerating itself. A rocketship is accelerating itself. As acceleration increases, its overall mass decreases. There is no more propelant left in the fuel tank. Hence, E=mc. So now your ship is drifting in space. Same as a sailboat on a calm day. Newton's 3rd law. For every action, there is an equal an opposite reaction. The spaceship can only go as fast as mass can be accelerated in the opposite direction. F=ma -> ma=ma. Mass does not increase with acceleration. F=ma/E=mc. Mass is converted to energy to create acceleration. Photosynthesis. Photonic energy is converted to plant matter with deceleration. Cold water has more mass than hot water. Acceleration does not increase mass.
And worst, the speed of light, although fast to us, is REALLY REALLY SLOW compared to the universe. 2.5 million years just to get to the nearest major galaxy. Interstellar travel is extremely difficult, intergalactic is just impossible.
Physics already tell us that Warp drives and creating holes in space/time is possible. It requires exotic matter but it’s only a matter of time until we figure it out. Speed of light will be inconsequential. To say “never” to anything is a bit silly
It is not inevitable. Concrete was a forgotten technology. As common as it was in the Roman Empire. Once it collapsed the big projects were no longer commissioned. Concrete was no longer necessary and the method was lost. If someone asked me to make a computer chip, or even a diode, I would not know where to start.
@@markharmon4963 Those of us who have made a "foxhole radio" know how to make a diode, look it up for fun experiment. Making a point contact transistor, the first one made in 1947, is pretty easy too. Concrete was rediscovered after a thousand years because recipe was written down and found again, so education with publishing and distribution of knowledge all around the world is important and a kind of "insurance"!
@@RWZiggy In order to create all of these things requires an economy large enough to support all of the supporting industries. That was my point. There is a window of opportunity here to be space faring.
@@RWZiggy Of course they could, if they new how and enough people new how and enough food clothing and housing could be supplied to these people who do nothing except study and practice how to make these things that are useless unless there is an electrical grid to supply enough power to make them by the millions so that an industry can be created to support micro processing. A library full of books is useless without the background understanding to interpret them. The space industry is languishing in mediocrity. This war in Ukraine demonstrates that the aerospace industry exists to sell weapons, not to explore. If we want to become explorers of space and the deep sea we should do it because there is no guarantee the future is going to provide better opportunities if the past has demonstrated space access has been deteriorating.
This is why warp drive is the only real answer to traveling the stars. In our dreams now but you said it’s not a matter of time for our speeds to increase. I think it’s true that it’s a matter of time, until we find a way to warp space. It is theoretically possible. It’s already been mathematically proven. It just hasn’t been figured out yet. Maybe in the next couple hundred years. Warp bubbles, if they can be created, negates the whole speed of light vs mass barrier. And it also should negate time dilation.
My favorite dialog line from mechanical engineer "Scotty", from the 1960's TV series Star Trek, is his telling Cap. Kirk that multiple/times of warp speeds will put us into the other side of the galaxy in a few hours is extremely funny. This is just plan "out there" and crazy/insane to even try to travel at such speeds. E = MC squared. Nothing is faster than (both) the speed of light and dark.
@@phillipmel that's a misunderstanding of what a warp drive is. The ship doesn't accelerate, but the space in its surrounding is distorted, so the ship goes forward.
the math they use to prove a warp drive is all made up the original nonsense. I wouldn't put much stock into any theory that requires the use of constants that are defined as, "defined by definition". lol. they say that all that bullshit is proven because someone stuck a clock in a plane and had it go up and down really fast but they don't really know why that clock reacted like that
@@qweqqweq2090 Don’t really know what you mean by, it was all made up. If I made up you mean a theory then yes it’s a theory. Theory doesn’t become a fact until it’s put into practice. Which is what NASA and some other organizations are working on right now as we speak. The original theorem said that a warp drive would need all the energy in the universe in order to power it. Which obviously is more than impossible. But over the last decade they’ve managed to narrow it down to the power of a sun. Which is still impossible with today’s technology. But that is still a huge breakthrough and step closer to making it reality. Right now the only 2 things keeping warp drive from working is the need to generate power the equivalent of a sun, and exotic particles. We’re already creating exotic particles. But it’s way to expensive to make enough of it to use in an engine. Warp drive is not a sure thing. It may never be realized. But the math and science is there. It’s just that technology isn’t there yet. So to say that we will never ever explore the galaxy or the universe, that definitely may be true (for us, the human race. We could all die out before we advance that far), but it also equally may not be true. Because the technology is possible, the question is will be create it before we become extinct. Only time will tell.
Sure, Just like we would never fly, break the sound barrier, land on the moon, create AI, make computers the size of a phone that are more powerful than a 1970 room full of computers, and travel to the deepest part of the Ocean.
Just a silly premise. You don't need to travel at light speeds to colonize the entire galaxy. That's the point fermi paradox: We know for sure we a civilization with our current technology travelling at sub-light speeds could easily colonize the entire galaxy within a few hundred thousand years. We don't detect those civilizations therefore we are most likely the first such one.
That or: 1. Civilizations wipe themselves out before they became interstellar. 2. They have a level of technology that we are not able to detect as yet 3. This universe is a simulation 4. They don’t want to be found and would rather observe our primitive society until we come to maturity
To be "the first such one", we first would need to be "such one", and we are not. Humanity will die on Earth. Yes the fact that it would take a long time by human lifespan standards wouldn't make it impossible. But it would still not be worthwhile for anyone to do it.
Do you know how far are those objects? Ort's cloud or the asteroid belt are not like in cheap sci-fi films, rocks that are so close that a spaceship should navigate through them, they are so far apart that if a spaceship passes, if there is an observer in that ship, that observer will have a hard time seeing more than a couple of rocks.
@@surangaputha You are asking that guy, who wrote about billions of planetoids? If you are asking him, I guess he doesn't know much about the Oort's cloud, he thinks those are so close...I wonder how he thinks we are seeing the stars if there are so many objects that is an "achievement" to pass through them... Many have such a picture of the asteroid ring, densely packed rocks of all sizes...
@@surangaputha Figures? What figures? about the Oort cloud? In pictures, it looks like objects are densely packed, but it is so big, that objects are approx. 50 million kilometers away. In the Asteroid belt objects are closer, but still, it is an enormous distance, approx 1 million kilometers away.
I'm afraid I agree, unless we find a way to open portals or wormholes, that is if they even exist. Someone made a graphic that shows the size of our 200 light year diameter radio bubble and it's place just in our own galaxy. It's pretty tiny, and it's 100 years of radio waves at light speed in all directions. It took the Voyager probes like Forty some years at 30 some odd thousand miles an hour to reach the limit of our little solar system. Not even seeing us colonizing Mars, honestly. Too many barriers to conquer and think of the vast resources that would be used just to get a few humans there so they can go hide in caves, away from solar radiation.
then how are those ET crafts getting here? like the ones Fravor saw, and that's only one sighting there are countless others. I think the thought that we are nowhere close to the most intelligent species makes people uncomfortable. cognitive dissonance or something. I have seen them too and know SOMETHING is getting here. they have been seen since before WW2 and sightings increased after the first atomic tests. but don't believe me, go back to burying your head in the sand where you feel comfortable. I'm sure the world's governments are trying their hardest to reverse engineer these crafts too, and wonder how far they have gotten. as soon as one of them does it will not be pretty. I hope humanity can get along before that happens otherwise ET is going to get a front row seat to our self destruction.
@@LisaAnn777 I don't doubt that other alien civilizations are able to get here, I agree with you there. I just don't think WE will be able to do what they are doing for a long time, if ever. As you said, we're too concerned about 'other' issues right now that pale in comparison.
well of course it seems impossible now..but I'm sure millions of years from now humans will accomplish many things we thought were impossible. I mean look at people who thought it'd be impossible to fly and the first airplane was invented in 1903. Then you fast forward 94 years to 1997 and we have robots on Mars. No one would have ever thought that was possible many years ago. I wouldn't be surprised if the first humans to land on mars happens within the next 100 years. Not to mention humans will continue to evolve biologically and technologically to reach greater heights than their ancestors could ever imagine. If you could bring someone back to life that lived let's say...200 years ago they would probably be in awe of the difference in technology. Imagine the technological improvements we've made the last 100 years and try to picture what will be accomplished even 1000 years from now. We know so little about many things at the moment...but I'm optimistic that we'll reach the stars even if it takes millions of years. Humans love and fear the unknown but we always strive to accomplish something that's deemed impossible. You should also look up NASA dragonfly where they'll send a robotic rotorcraft to Titan - Saturn's largest moon in the search for origins/signs of life.
I believe that over 100 years ago, thinkers believed it was impossible to go past 40 miles per hour. We are just touching the surface of things we thought was impossible.

I like it, we do have some connection with nearby Alpa Centuri system through our respective interstellar space, not all empty, hopping a bit at a time would make sense, until we see some genius whipping by at relativistic speeds to beat us to Proxima B, but it will likely be uninhabitable any way and they may have to move on to Barnards star say. :D

I'm glad to see you mentioned two problems with near light speed interstellar travel that are often ignored; the possibility of catastrophic damage to the spaceship due to collision with interstellar matter, and the large difference in the amount of time that passes between the space travellers and their home planet (and destination). And you also correctly noted the answer to the Fermi paradox; the fact that aliens haven't visited us doesn't mean they don't exist, but merely that they (like us) cannot travel the vast distance from their planet to Earth. I would add that even if someday we discover Einstein was wrong and there is a way to travel faster than light and aliens developed that technology, how would they know about us, and why would they decide to visit us even if they did? Our galaxy is a huge place and here are billions of planets in our galaxy alone. It is very unlikely aliens would know we exist and even if they did they probably have more interesting places to visit.
I think if we were to find the ability to travel the distances the first place we are heading is where there might be other life. It seems to be rare, certainly the search for Habitable planets alone would bring them to our solar system at some point, Earth is a jewel in a Galaxy or rocks. We can discover big planets around other Stars I bet people 1000 years ahead of us can do much more.
@@streamofconsciousness5826 there is life out there,it would be arrogant and narcissistic to think we are alone but please remember ,as on our own planet,life does not always have to breathe oxygen or be Carbon based. So it’s quite realistic to hypothesise,in fact it’s essential, that our planet would not be attractive to most of the other life forms out there.
I believe it is possible, but I also understand your realism. Although seemingly impossible, there is still so much we don’t understand yet-I don’t think it is time to give up yet with a poopy pants attitude. You run a marathon one step at a time. Let’s continue to search for a way…and besides, what else are we going to do?
@@jonothandoeser it’s not rationally possible with our current technology, and definitely won’t be possible if everyone has poopy pants can’t do it attitudes. Miguel Alcubierre’s theoretical warp drive utilizes a soliton warp bubble to move at speeds 10x the speed of light. If we can create a warp bubble inside a warp bubble, it may theoretically be possible to travel at 100x the speed of light. From what we now know, we probably will not get the energy needed for this until we can use self-replicating AI bots to create a Dyson sphere. We are close to nuclear fusion reactors as well which could be utilized as energy for the soliton creation in warp drive. Imagine another 1000 years of technology advancement. In the 1800s we were traveling by train. Now we have rovers analyzing Mars’ surface.
What you are saying is pretty much this. "If we keep practicing the high- jump, eventually we will be able to just jump into outer space!" But what about gravity? "Well you run a marathon one step at a time!" Not EVERYTHING IS POSSIBLE. We need to learn that.
@@jonothandoeser ok poopy pants lol. It’s going to take both a lunatic dreamer and a poopy pants practical thinker working together if it will ever happen. We need each other.

Now YOU are on the right track! I would take those trillions and trillions of dollars that it would take to land people on Mars and spend it on every possible idea that we can come up with on how to get along, AND preserve a planet that we already KNOW has life on it. All kinds of beautiful life. Wonderful creatures of every kind. Walking, swimming, and flying. Plants and flowers. Beautiful trees, and rainforests.

Perhaps. Some think they are time travelers from our future, not buying it either; but both might be easier to do in 5.5 million years from now. We do have to get off this rock a bit soon though, what with the likes of Putin and CCP creeping around, before they muck up the works and prevent anyone from doing anything here again, science-wise. Some possibilities in our own little sand box.
The only other life outside our own is the infinite amount of clones of folks back here on Earth existing in a possible infinite universe in length and width.
Yes, JB, good comment. There's not anything that we could gain nor learn from space travel that our probes have already told us. The super-far distance that both Voyager space probes have gone verifies this fact(s): The out-of-our solar-system region is mostly a void of dark matter with very little resistence to radio signals (from the Voyagers) through this open-matter. It has so little of what we would regard as molecular density, or even anything other than darkness, void and vacuum, that taking any trips by humans would be pointless and suicidal.
"Never" means: Not in 1000 years, not in one million, or one billion. Never is a long time. But it depends on what you mean by "we". We personally? Or our decentents? Our decentents could be machine like and thousands of years could be doable. On the other hand, millions of years is time enough to make some good progress on technology. Maybe long distances are feasible for organic creatures too.

I believe we will reset our civilization few times before we make any progress remember the so called mass distraction weapons ? And also remember who we are ?
We'll continue to explore it from a distance like we always have. But sending manned mission to other planets and solar systems will never be in the cards, especially, if the goal is to have them set up (semi)permanent habitats and settlements. Also by definition the Moon is still very much attached to the Earth's gravity.
I came to the same conclusion years ago that its all a pipe dream and went to bed depressed realising I would never ever leave this world, never see anything of this universe and it seemed really unfair and wrong, then I had a dream, I 'woke up' and found myself floating in deep space watching the earth slowly recede in the distance, I was not alarmed or bothered as in a dream when an old raggedy clothed wild haired man appeared, looked like an Indian mystic or Tibetan type sitting cross legged and he had a black stone like obsidian on his forehead, he looked really annoyed and miffed and his very deeply wrinkled face looked like it was scowling and he grimaced and said " It takes 86 hours to travel the universe" nothing more and then he disappeared to a point of light and I woke up, hell of a dream but it got me thinking perhaps there is more to this game than meets the eye. wish he had of said how.. lol.

@@ericgolightly8450, we're talking about two different categories. You're talking about "not-yet-possible" and I'm talking about "not-possible-at-all". In the year 1900, if I had told them that 80 years later high-jump over 6 meters would be possible, just by means of a long rod, they would think I was joking. That's something that was not-yet-possible at that time. However, if I had told them that several decades later a person would jump 600,000 meters by means of a simple long rod, they would think I was crazy. And they would be right, because such an enormous jump is not-possible-at-all. Interstellar travels are not-possible-at-all even for more reasons than are mentioned in the video. They are just a figment of imagination on the part of some quasi-scientists, whose task is to distract people from important things by engaging their minds in things that are not only impossible, but also stupid. And it's not just intergalactic and interstellar flights, because interplanetary journeys are impossible, too. It is questionable - albeit maybe not fully impossible - for people to reach the Void above the last layer of our atmosphere. If you are a) intelligent and b) objective, you'll be able to figure out yourself at least some of the problems that make those flights impossible. All you will need is just a little knowledge and a high quantity, of logic. Actually, even a 15-year-old intelligent boy would figure it out, if he only knew the basics about the Universe, the most crucial of which is the fact that all bodies there have always been moving. Which means, there is no chance for us to know WHERE a certain planetary system is, given the fact that it doesn't stand still. If it is 50,000 lightyears away from us, it means that it WAS there where we see it 50,000 years ago. But during those 50,000 years it crossed a large distance, and we can't know in which direction. If it is moving away from us, it may now be 60,000 light years away. If it is moving towards us, our super-fast starship may collide with it. Besides, we can't know if the spot where it used to be 50,000 years ago is empty now, or taken by another object - a black hole for instance. There is no way a starship could travel faster than it is needed so as to detect and dodge possible obstacles on its trajectory. If you travel with the speed of light - as if such a thing was ever possible - you could never dodge a body that crosses your way, so there is NOT A TRACE OF A CHANCE for a starship to reach any destination, because it will be destroyed very soon after it accelerates. Just a little basic knowledge, a good portion of intelligence and a high amount of logic.
@@Yora21 lol better idea? No? Bc there's not a better idea. It's called distance and sacrifice. Yeah we can send dumb probes but that wouldn't be colonization would it?
Advancements in relationship to time have compounding effects. Meaning the time it takes us to make great discoveries not only shortens but as the frequency of discoveries increase so does how impactful the discoveries themselves are. What we make advancements on in 10 years will dwarf the previous 50. The next 50,000 years will make the previous 50,000 seem like nothing. Imagine bringing just a simple mirror back 50,000 years ago lol.

Build the spacecraft like an arrow. Have like 100 solar sails with self-repairing material, detectors, deflectors, pulverizers and incinerators at the front of the spacecraft.
This is a compelling video, but I do have a qualm with using the Fermi paradox as definitive proof that no civilization is capable of interstellar travel. The Fermi paradox asks the question of why we see no technological signatures at all, not just signs of an interstellar civilization. That includes radio signals, the presence of certain chemicals in planets' atmospheres or signs of certain large-scale structures such as Dyson spheres that a civilization colonizing its solar system might be expected build. None of these things requires the civilization have faster-than-light travel, yet we have not seen any of them. So we don't have conclusive proof of any type of extraterrestrial technological civilization, but since our own civilization exists we know they are possible. Therefore we can't use the Fermi paradox as a basis that interstellar travel is impossible, because using that line of reasoning there are NO other technological civilizations besides our own period (and if by chance that's true, that renders the argument moot, because there's no other civilizations to compare) . Now, if at some point we do find signs of ET intelligence but find it appears they have not traveled beyond their own solar system, then this premise holds much more weight, but for now I don't think it's the "nail in the coffin" argument against interstellar travel.

I've seen people claim with certainty that "Some day, surely, we'll achieve the engineering needed to reach light speed!" But how is humanity supposed to overtake a speed so fast that matter becomes almost entirely indistinguishable from energy? Humans die from seconds of exposure to gravity six times earth's gravity. These would involve forces HUNDREDS OF THOUSANDS OF TIMES Earth's gravity.
The reality is we don't need to reach light speed to become interstellar. If nuclear powered ion propulsion can get us between 10% and 20% light speed we can reach neighboring star systems in less than 50 years, and we could close the gap to a couple of decades. We don't need to send people right away. We can send lots of probes that fly by and take pictures, then robots that go into orbit or land. That means it will take about a hundred years for each star hop, but in one hundred thousand years that's a lot of star hops, and a lot of the galaxy and nearby stars systems explored.
@@vidyaishaya4839 If humans are able to accelerate to 20% light, we can only travel at 10%. The remaining 10% has to be used for de-acceleration.

@@oldmech619 it will take a while to speed up and slow down, but not half the trips. That's why individual trips will be less than 10 light years in length.

Interstellar spacecraft will be huge, capable of carrying up to a million people, but thousands at a minimum. They would have to be self sufficient, and large enough to be a world of its own. It would also need to carry enough resources to begin a new colony in the new star system. While most of the people would leave the transport, enough would remain to go to the mext star system and populate up during the journey.
If you tell someone 200 years ago that you’ll be able to go across the world in a matter of few hours… they would probably think you’re insane … Kind off how we thinking about interstellar travel right now
Having an interstellar civ. and simply travelling to other stars are not the same. None of these disprove ships travelling below 0.1c to other stars. But even at 0.1c trade between stars can very well happen. Such trade would only involve extremely basic objects such as energy, water, hydrogen, anti-matter etc. and in large bulk. These kinds of trade would happen in simple barter system and won't involve any currency but such trade can happen by means of large generation ships travelling between stars even at below 0.1c. So yes, you are wrong in saying we would never travel among stars and you are wrong in saying that humans living in different star systems cannot communicate in any meaningful ways, but you are probably right that there will be no interstellar govt. But then again the future can always surprise us so best to include a probably in your "X will never be" predictions.
depends on a few questions: 1. what you mean travel, since regular travel mostly out of the question, at best a normal human will move from star to the next, and that will be an achievement by itself for the person. 2. what we consider under human, if we solve aging in one of the many potential why (mechanical replacement, de-aging biotech, mind transplant) than suddenly a ten year trip is no longer than a year long voyage was for the people in the age of colonization. 3. how far we willing to move from humans, a digital mind on a computer by definition ageless, and a computer can be accelerated much more than a human, so faster trips for near limitless time, no issue with actual proper travel. And if it is a program anyway, we can just send it without any issue, more of copying but still a version of the mind will travel. 4. we, as in humanity, the race, not the individual, sleeper ships, colony ships, or seeder ships are all possible with current tech, and will be more and more possible in the future. with fusion (if it ever arrives) we can simply create self sustaining colonies, which if they decided just travel among the stars, every century or two apart, they arrive to a system, replenish whatever they need exchange culture directly with the systems local population, and goes on. So yes, we will travel between the stars, just do not limit your imagination to what sf tells you, they are bland to what the future will be.
Guy, he addressed just every single aspect of you comment, which you choose to ignore. I'll add another, money. Who's going to pay for your sci-fi fantasy, and for what purpose? We're talking about staggering sums of money here. There is nothing worthwhile in what you say to equal that.
Unless you're referring to some hidden, suppressed form of technology, then I would say that no, we don't currently have the technology to develop/launch seeder ships into space. The problem with fusion technology is that it produces a form of energy that we still can't directly harness. It would still need to be converted into pressure from steam. True, it's a virtually inexhaustible form of heat energy, but is not usable with current technology for space travel, let alone interstellar travel. You would need an endless supply of water to convert to steam. And even if you were able to develop a closed loop system where the steam is collected and returned to liquid state, there'd still be losses, with the strong possibility of something breaking down. It's not a reliable system for travelling tens or hundreds of years in space.

@@Aquascape_Dreaming The heat plant part of the fusion power plant is very well done, since it is used in every heat plant on the planet, in a closed loop, you do not need any external water for that. You need some fuel for the fusion plant (and that will be tricky to source, depending on which variant can we work, if any,) but that will be very small amount compared to the entire system. For the fusion drive, yes, you still need something to exhaust, but much less than with current rockets (even the least complex fusion drive ideas gives us Isp in the thousands, compared to the chemical fuels 550 or less) not to mention that with ready supply of energy you might just go for an ion or plasma drive, it will be slow anyway, but gain the benefit of 30K+ Isp.

Let 'em go, and see how it works out for them. Problem is, we may never know because they'll be too far away for their message to get to us. Our language may be indistinguishable to them by then.
If physics works definitively against us for interstellar travel, I believe we'll be able to download our consciousness into super computers...buried underground and able to "live" as long as the earth remains intact. A perfect world of our own making. The technology to do that seems more probable than far flung space travel. I would guess that it may be possible within the next two hundred years considering how quickly we are advancing in that area.

I don't think you fully understood the video. It's not about technology, it's about physics. Even IF you could travel 90% the speed of light, it still wouldn't be possible. Do you even understand physics well enough? The only thing that would make this possible is the be able to travel much faster than the speed of light and not even doing it by travelling through the medium of interstellar space. Technology? Basically what you want is faster than light travel and you'd have to be an idiot to say such a thing is possible. No "worm holes" are not a thing, they are purely theoretical.
Not completely. We can do it with Newtonian physics. We need fusion power though but we can see that's happening in the sun so that isn't a theoretical possibility it's real.
Yeah. Title is just click bait.

A 10% C speed would allow a trip to Alpha Centauri in just 43 years. Question is, how well do we understand the density of interstellar debris?
that's right it's not just about speed, everything human build that we use in all aspect of our daily lives are not designed to last more than few years. This is what those scienfiction films always fail to address. You can invent some kind of hibernation for 200 years to get to the next habitable planet on a spaceship. But that spaceship cannot take a break, it is working hard everyday to stay functional. So far no human technology can make simple computer, power supply, circuitry that can last even decades without total replacement. Just look at the ISS, or any any human made space object now, without constant maintenance they all break down completely in just few years or months even.
I never say never, but right now its impossible to travel to another star, imagine hitting a small rock at the speed of light
That would be 10% average. To get the average, you need to accelerate well past the average, then decelerate at the other end (assuming you want to stop to have a look around). Accelerating a mass requires energy, and the mass increases with velocity. An enormous amount of energy is required to get there in a hurry.
Remember that time goes slower the faster you move, according to Einstein. So it may be possible that it is 43 years, for the dude in the shuttle it isnt.
@@kamikazekrush3758 A grain of sand at the speed of light would wreck a spacecraft. At that speed even individual hydrogen atoms in interstellar space becomes an issue.

I mean I get it to have low expectations especially with current technology and political issues. I mean survival’s sake the planet will face resource limits then we might explore space or other solutions to accommodate those resources.

We know nothing. We only know about 5% of what there is to know. Dark Matter (22%) and Dark Energy (71.4%) surround us, yet we have no idea what they are. We SO don't know that we just call whatever it is, "dark." Maybe we just need some more time to learn as we're just infants yet...

@user-nt5wt8tr7n I Suppose you're the life of the party when you walk up and tell people, "I put my fingers in my bum bum" then?
I'm guessing you have no idea what the Fermi paradox is.
The reason why there are a group of people who have a bias toward interstellar travel not being viable at all, is because that opens the possibility more that we are not alone in this galaxy (as in there are other advanced civilization in this galaxy).
These people are so biased toward the idea of not being alone in this galaxy, that they come up with excuses like this.
If interstellar travel IS possible, then that means we are alone (in this galaxy).
This is one of many "excuses" for why the galaxy hasn't been fully colonized, and overflowing, by another civilization/s.
Such excuses are called "The Great Filter". I.e. "something is keeping spacefaring civilizations isolated from each other". Interstellar travel being unstainable is such a "Great Filter", among many other hypothesized possible Great Filters.
You have to choose one, because statistically it's exceedingly unlikely for both to be true. Either we are alone in this galaxy, or we are not alone but merely isolated because interstellar is not viable.
I personally agree with you....we are alone in this galaxy...and interstellar travel is inevitable. eventually, in a relative blink of an eye, we will colonize this entire galaxy.
And if at least one another civilization existed before us, they would have done the same by now.
In just 3000 years, if our energy needs continue increasing as is, not even the entire energy of our sun will be enough...a million years is like a split second compared to the age of the galaxy. Imagine a civilization that came a few split seconds before us...the galaxy would be entirely covered by them.
Unless interstellar travel is something that would prevent that.....
@@tylerdurden3722 You are assuming a lot of things which are questionable. First, you assumed we are somewhat the youngest civilization. What if we are not? And actually one of the oldest? It means that technology hasn't been discovered. Second, Interstellar travel to nearest star vs. distant or other galaxies. There's a big difference in that sentence right there. Interstellar travel only means "other stars" which can be a nearby star. Many other questions exist. What if other civilizations are just too far and their nearest star is all they can travel to? At least by their present technology?
The same with us and our future technology. Also, you are assuming again that other civilizations should have been more advanced and would have already travelled in out star. You are also assuming our understanding of physics as of 2024 is already fully understood which is actually very far from the truth. Are you sure our technology and understanding of physics today will be the same 10,000 years from now? I don't think so.
the frustrating thing about lightning speed is that it is still frustratingly slow compared to the size of our galaxy or others, if we attained the possibility to travel at lightning speed we would still be like a snail trying to travel around the earth's circumference
lol. I’m afraid it would be a lot worse than that. The snail would slither a thousand circles around the world before we made even one light speed trip around the Milky Way.
for starters we could very well settle for something like 0,3 of the speed of light .
more than 10 stars are within 10,5 ly away from us .
which means it would be possible to make a trip to them .
trip to alpha centauri would only take circa 14 years at 0,3 speed of light .
and engines 0,1-0,3 of the speed of light are already debatable (or at least possible in theory) .
we don´t need to colonize the entire galaxy any time soon , we just need to build good enough engine to get us out of this rock and to colonize
at least closest star system , that way we don´t end up being wiped out by a single catastrophic event .
from there we can further develop our technology ,
we will have literally hundreds of thousands of years to improve once we are no longer just a one planet species .
you have to temporarily change dimensions....the 'material' world

@@tracedog27 Yes, you are right, but you have to consider time dilation. When you travel at the speed of light, time seems to stop from your perspective. So, if you want to go to Alpha Centauri, which is around 4.3 light-years away, the trip would only take a few days from your point of view as a traveler
Lightning speed is actually slower than the speed of light. But it is true, the Milky Way is about 180,000 light years across.
My grandma just passed at 95. She told me jets used to be in books and people would scoff at the absurdity of travelling at the speed of sound. It we make it, say 1,000 more years who knows.

There is no fundamental physics barrier about space travel, what so ever. If there were, the universe wouldn't be teeming with solar systems and galaxies like it is.

according to guy who made the video yes.
But I would say, probably everybody is expanding their reach, at 99.999999% the speed of light, but they're taking it slow.
A combination of that and SETI is simply not sensitive enough to draw any conclusions yet.
They would have to be able to pick up accidental signals such as weather radar on another planet.
The most probable aliens would be some kind of quantum robots, not any naturally evolved being. And both unlikely

@@wiseomg Did you ever see Planet of the Apes? Charlton Heston proved flight to the apes by making a paper airplane and throwing it. Do you honestly think people of a thousand years ago and even 10,000 years ago didn’t simply understand the intuitive physics of watching insects a birds and realized that your lift potential from wings, let’s say, plus speed must compete against your weight or gravity? Shit, I was five years old and tried it with “home made” wings and realized I was just too damn heavy. But I understood at that tender age that there was no barrier or law of physics preventing me or animals around me were doing it. It was just a flaw in my design. I needed counteracting energy to the force of gravity. You cannot honestly believe a journalist who wrote an article once and assume the great thinkers of Ancient Rome, China, India, Egypt or Greece didn’t contemplate how to overcome the struggles while arrows and rocks were slinging everywhere in warfare and motherfucking birds were doing it too. It was only a question of engineering. So the ancients figured out Pyramids, aqueducts, gunpowder, geometry and that the earth is not flat but no, no flight is obviously not possible. Pythagorus and Euclid could not conceive of such a thing.Hot air put into a confined space, like a ballon delivers lift and sufficient force to counteract gravity. I once heard from a journalist that I need to wear two masks while driving in my car alone to protect me from CoVid. Uh… okay. I would go with science and simply say that flight was never defying the laws of physics, like saying going beyond the speed of light/causality, and was a simple matter of achieving the engineering skills to produce it. Read “the Flight of Icarus” in Ancient Greek mythology and see that a boy with feathers held together by wax, but he flew to close to the Sun and they melted, is an achievement of understanding that “we simply cannot do it yet,” not that it is impossible unless you hold religious views that somehow banned it. My own faith never “banned” it. So to close, just use a little common sense here.

@@kvarnerinfoTV Yes, Alcubierre demonstrated there's nothing preventing the warping of space to achieve faster-than-light travel. The problem is the energy required to do it would be something on the order of what you'd get from a black hole. So, until we're able to create artificial black holes, harness their energy, and use them to power an Alcubierre Drive, we're not going anywhere; or at least not going anywhere very quickly.
If we're serious about colonizing distant worlds outside our solar system in the near-term, it's going to have to rely on generation ships or some form of cryosleep / hibernation / suspended animation.
@@JohnDoe-zl6qw energy requirements for a alcubierre drive are being smallaer and snaller with every new paper. I am quite positive that in next few decades we will be able to lower it to acceptable levels.
Also we will soon have tech to reach near light speeds so closest stars will be far closer...
@@kvarnerinfoTV The power requirements may be decreasing, but reading deeper you come to realize the power requirements are still (A) astronomical relative to what we can produce today and (B) rely on something that is currently being called "negative energy".
With regard to (A) the original calculations called for a ball of antimatter the size of Jupiter to power the Alcubierre Drive. That's since been revised down to one the size of the Voyager 1 spacecraft. Sounds reasonable, right? Until you realize the only anti-matter we've been able to create has been in particle accelerators/colliders. In 2010 the Large Hadron Collider created a total of 38 anti-hydrogen atoms worth which lasted 0.166 seconds. More has been produced since, but still in equally infinitesimally tiny quantities. We're a long way off from producing tons of anti-matter that will remain stable, let alone that could be safely stored and transported to be used aboard a starship.
Also, there's no such thing as a free lunch. It takes energy to power a particle accelerator/collider. You don't get to create energy out of nothing using such a device. The energy you wish to store in anti-matter has to be energy you put into the accelerator/collider. The amount of energy stored in a Voyager 1-sized ball of anti-matter exceeds the total energy output of the entire human race the world over at current production levels. So what do you propose? We all stop using electricity and burning coal, natural gas, and oil for a year so a theoretical warp drive can have enough fuel for a test flight?
Then there's the economic burden. It's estimated 1 gram of anti-matter has been produced in total by all experiments to date that have attempted to do so...at a cost of one trillion dollars. At a launch weight of 1,797 lbs, a Voyager 1-sized ball of anti-matter would cost $815,105,542,800,000,000 (that's 815 _quadrillion_ dollars). Where's that money coming from?
With regard to (B), we have no direct evidence for "negative energy" yet. It may not even exist. Alternately, it may turn out to have ties to Dark Energy or Zero-Point Energy. Regardless, we're still a long way off from even being to able to construct an experiment to witness it let alone harness it (if it even exists).
I'm not against the advancement of scientific knowledge and technology and would very much like to see us achieve some form of propulsion to take us to the stars. However, dreams must be grounded in reality if you ever want to achieve them. There's far too much dreaming and not enough grounding when it comes to these discussions, with a flippant disregard for the overwhelming technical, engineering, social, and political challenges it presents.
We are not even remotely close to being able to build a working Alcubierre Drive in our lifetimes. I'm not saying don't pursue it; I'm simply cautioning one needs temper their expectations and to be more realistic with regard to the timelines involved.

Its not just about getting up to speed and the risk of possibly hitting something its also about trying to stop once you get there. You cant just stop in space going that fast.

The dilemma that has always confounded me when I think about space travel is one of simple
Geography. The information we have (ie, what we see) is old information. The light from astronomical sources we see is old (as much as thousands or millions of years in some instances). Those objects have moved in that time (the galaxy is rotating and space itself is expanding). Flying to Vega, for example, is not like flying to Vegas. Because Vegas is always in the same location. The best we know about Vega is where it was located 25 years ago. Although Vega is “close” and unlikely to have moved much “galactally” in 25 years, the problem is much worse for more distant stars, let alone locations outside our own galaxy. Also, we all know stars go through phases, one of which includes a supernova. Given we are always acting on old info, it is entirely possible we could chart a course to “Star Z” only to find Star Z has exploded in the hundred or thousands of years it took its light to reach us when we charted the voyage. Creating reliable and “dynamic” maps that adjust for historical movement of objects and future movement (during the time it takes to make the journey) strikes me as a daunting proposition in and of itself.
Vegas has moved just as much as Vega. The bigger problem is knowing where you will be.
Trajectory to Mars and other astronomical objects is planned based on its location in its orbit around the Sun by the time we get to the destination. It is possible to predict the movement of nearest stars in respect to our own or in respect to the centre of the galaxy, so it should be possible to chart a course, accurately predicting its location by the time we arrive. Even working with old info, we should be able to predict the current state of the star in the present VS. the apparent (X ly in past). Unless there are clear signs of a star going supernova or it being on the other side of the galaxy, 1000 or even 10 000 years is just a blip on astronomical scales so it is unlikely for a star to disappear in that time.
@@ilmarssalna8900 Uh, the light from Mars reaches us in 2 MINUTES.....Yes, we can account for that and predict where it is going to be. You could probably even make assumptions about things with 100s or 1000s of light years away. But You cannot know with any reliability where something is going to be or even if it exists if that light is BILLIONS OF YEARS OLD...
Motions of stars can be predicted just as the motions of the objects in our solar system, assuming you're trying to reach a reasonably close star. If your destination is so far that you're worried your target star having gone supernova by the time you arrive I'd say you've got other problems. :')
Conveniently the same laws of physics preventing you from observing the "present" state of a distant object will prevent you from reaching it...
Probes. We would send probes to cut that useless flight out of the equation if traveling faster than light were possible.
We never thought we could fly, we never thought we'd break the sound barrier, but we did, I'm sure, if it's at all possible we will find out 😊

That's a bold statement, but I have to agree it is a remote possibility. To date, moving any mass beyond the speed of light is impossible. Even accelerating to 1/2 the speed of light would kill everyone on board. Even at 0.1C it would take 40 years to get to the nearest star. The whole "folding space" thing is just hypothesis. Gravity can bend space but even if we could build some kind of gravity generator the power required would dwarf the current global output.
If it took 40 years to reach the nearest star, and we sent colonists to the Proxima Centauri system in 2050, then we'd have humans living in another solar system by 2090. That's... not very long compared to the length of human history.
@@adammclaughlin845 While there's without doubt a sheer infinite number of Earth-like planets or moons sprinkled allover the observable part of the universe, the chances that one of those happens to orbit around one of the closest 1000 stars is probably quite small.. and almost certainly there's none in the A Centauri system. So this would most likely be a very educational one-way trip much better done with unmanned robotic probes. (Not even talking about the energy/propellant problem, sufficient means of life support, high energetic cosmic radiation and collisions with cosmic molecules/dust/micrometeorites...)
Not a remote possibility, but the most likely scenario (says someone who studied astrophysics). It's not just not possible to move any mass beyond the speed of light "to date", we have not observe this happening ever, even in the most energetic cosmic particle accelerators observed (active galactic nuclei, GRBs, supernovae), and if it were possible at all you'd think that those objects, which output energies a trillion times higher than the largest particle accelerators on Earth, would be able to do it. Even completely massless particles such as photons (eg. light) travel only with "c", not faster. So if it were possible to somehow exceed this fundamental speed limit, it's not something that could be achieved with the help of any of the known types of matter or force fields - and if there are particles that indeed do move faster than 'c', they have yet to be found, and guess what - your or my protons/neutrons/electrons etc forming carbon, oxygen, hydrogen etc. atoms of organic or inorganic matter as we know it are definitely not among them...

I like what your saying and I agree. Right now these are barriers we cannot break and in time I'm almost certain we will.

It's the law of physics that you can't travel as fast or faster than the speed of light.

Fantastic answer 😉
nope maximum our solar system beyond is unlike is too far away people don't have any idea how far exoplanets are far away
I always hated that cliche, "Believe me" when anyone is talking about a nebulous subject such as interstellar space travel. To me it quite arrogant and even narrow minded to think that we will never travel to the stars because that belief is based on the very limited understanding we now have of the universe and the fundamental physics that make it go.
I set no limitations on human abilities. However our greatest threat to not reaching the distant stars is our capacity for self destruction. The world is in a very precarious position right now and many research scientists feel that are already well into a Sixth Extinction event.
But assuming we can overcome our many short comings we may in future centuries discover physics we can't imagine now. It was with great naivete that at the turn of the 18th to 19th century many physicists thought that was nothing new to discover in physics.
In the same way I find it short sighted that people think that we will never travel to the stars. And when people reject the idea of traveling to the stars it is always with the same single minded focus that physics says it is impossible to travel at the speed of light for the reasons given in this video.
This narrow minded thinking prevents those same people to imagine an alternative mode of travel through the universe that does not rely on traveling anywhere near the speed of light. But we are perhaps hundreds of years away from discovering the physics that could make that possible and we must learn to overcome our differences IF we might possibly live that long. There are of course the natural threats beyond our own capacity for self destruction!!
Despite these many obstacles to realizing deep space travel many of us will continue to dream of what could become our future, distant though it would be.
Edit In the 3rd paragraph I meant to say 19th and 20th century.
Thank you for your comment. At one point man didn't know what fire was. Then he discovered the wheel. Then many eons later he learned to master the skies. It's my profound belief we will become an interstellar species. Once we reach that level of advancement there's no stopping us.
Given the shortness of our lives, you are right that this will not happen in any MEANINGFUL WAYS TO US. That is why the answer to Fermi's wonderful question: "Where is everybody?": is that they all stayed home, since they had no choice.
They said that we would never travel the globe, today we have planes that can circle the earth within the hour. Not long ago we produced a nano warp bubble. Which people said would never happen, yet it happened. It is people like you that give humanity the strength to push on, and we are likely on develop warp drive before the end of this century Galactic domination is inevitable.
Also the warp bubble stops time dilation and makes the warp process possible. The whole process is rumoured to be able to work on a fission rector….

Going deep into the ocean is much harder than going into space.
We can, we just haven't yet.
We can't accelerate anything to or past the speed of causality.
Even if teleportation is invented, it will be limited to the speed of causality.
Even theoretical wormholes reveals this limit in it's math.
In other words, it's not possible for the Effect to happen before the Cause.
E.g. you can't make the cause and effect of lighting a match happen in reverse order.
Moving faster than the Speed of Causality would result in such things. You'll be able to arrive at a destination, before having left your departure point. In fact, if you go fast enough past the speed of light and make a return trip, you'll return before you left.

It is easier to fix all the problems in your planet than to try and invade others, at most i believe we could land of asterpirds or meteors and extract materials from there.

I'm an "older" guy (in years, not in life style). Ex-news-guy, and been putting serious study time into Astronomy, especially the long distances between space objects. For one, the alignment of the orbits of earth and Mars get close enough for inter-planet, only every 26 months. This means that the suicide "voyage" to Mars would be just that, a way to become a gamma-ray bombarded "crispy critter". So this voyage, with any humans, would take a minimum of 2-and-a-half to three YEARS. The "space ship" would have to be half the size of big Star Wars flagship/cruiser. It would have to be assembled IN ORBIT of the Earth, a task that would make the Interna'l Space Station seem like a tinker toy in comparrison. And going to any other planet (mainly Jupiter) would be way too far, a round trip of 5 to 6 years minimum. No human will ever go any further away from our Earth's moon, EVER. The cost would be enormous, and we would not learn all that much more than our various space probes have already done. We know what is there, and practically speaking/witting, sending any humans there is a waste of time, effort and money. { : - } ~~
I forgot to include this: A transit through space will not include any fast-travel portal or wormwhole. These are speculative notions, and a part of what is known as "Science Fiction", and not even remotely available. Wishful thinking, that's why Science Fiction is, and just this: A story not able to be regarded as "true" and/or possible.
Yeah the thing everyone forgets because they're so focused on theoretical propulsion systems is the fact that even if we managed to go fast enough that long-distance space travel was on the table, the REAL problem is radiation shielding. Until we solve the very, very, very real problem of figuring out a practical way to keep our astronauts from getting lethal doses of radiation on their trips, we're not going anywhere.
Our ISS orbits well within the Earth's magnetic field. But radiation was an extremely serious concern on the trip to the moon, even though it wasn't publicised. An inopportune solar flare or other gamma ray event would have had catastrophic consequences for the Apollo astronauts. We just chose to roll the dice and hope for the best, and it worked out. But longer-distance travel will absolutely not have that luxury. And lightweight, durable, and effective radiation shielding is every bit as difficult a problem as high-speed theoretical propulsion.
@@Dr.TJ_Eckleburg Your explanation of these facts is better than mine, and I appreciate it. So now the challenge is to get people to stop believing in Elon Musk's "solutions" to our mutual problem.

This vid is ill-named. It should be called "Why We Will Never Travel Faster Than Light."
Traveling among the stars is no problem at all, as long as you don't mind the fact that it will take a very, very, LONG time. Many different methods - all perfectly acceptable to the laws of physics - have already been preposed. Suspended animation for the travelers. Generational ships where those that arrive are the descendants of the original crew. If ion drives work, it has been shown that with the constant acceleration you can get to Proxima Centauri in one human lifetime... a one way trip where you won't have much time to accomplish much when you arrive... but we CAN.
Even trade is possible with decades long plans run automatically with no communication needed. So many shipments per year of X in exchange for so many shipments per year of Y for the next 100 years or so carried by automated unmanned craft. That works fine with planning and patience.
Never travel amongst the stars? I scoff. Of course we will. The only question is how distant in the future this will be as we balance our desire to do it faced with restrictions of physics... which aren't restrictions at all if you think in terms of generations of humans and decades and centuries of implementation. And all this presumes that the average lifetime of humans shall remain as is. If you do some research on aging and proposed methods of its prevention, you will see that surprising progress has been made. In a couple of hundred years the human lifespan may have been greatly increased.
It is almost guaranteed that the life in board any space ship won’t last long as space itself is lethal to life
Astronomers found out recently that there are many pockets of space which look empty but are made up of dark clouds with unbearable temperatures and radiation which no life can get thru, the list of dangers in space to any life is endless, there are literally 6 billion way space can and will kill you
So yes the video title is right, humans will NEVER travel interstellar but the AI humans make in the future will since they are not vulnerable biological creatures like their creators
On the topic of trade, why would trade even be necessary? There is an unimaginable amount of resources out there, a small colony of 10,000 guys in Bumfuck nowhere system would possess 1000 times more wealth then then entire earth combined does now. Trade would be a novelty, the only meaningful trade would be that of ideas, and ideas can be transmitted at light speed via laser communications
The nearest star system is less than five light years away. We only need to reach 10% of light to get there in less than 50 years. We should be able to send a probe at that speed before the end of the century. Given another hundred years we should be able to scale that technique to human travel. Less than two hundred years is far from "never."
And I would like to add, if we can go to one habitable exoplanet in the galaxy, we should be able to colonize all of them in an exponential process.
If we can go to proxima and establish a presence there, we can eventually develop that and turn it in turn into a launchpad to a system under 10 ly from there, etc, etc. With each system we take our capacity to grow increases too. So we get a positive feedback loop of continious growth until the entire milky way is taken.
The most interesting number is the average of the minimum distance between habitable planets in the galaxy. Because you are severely hampered if you have to use Mars like rocks in this process compared to habitable planets.
@@dekippiesip exactly! I figure we can at least average 10% of the speed of light at colonizing the galaxy. It's round, and our path will be in both directions around the outside of the galaxy. The inner parts of the galaxy are the most dangerous for life.
Multiply the diameter of the galaxy by pi times 10 and you have an approximation of how long it will take to colonize the galaxy. We'll also spread out to many other minor galaxies, and be ready for Andromeda when it gets here.
There's one last thing. The problem with habitable exoplanets is they are likely to already have someone or something living there. We may only send scientists if simple life, or trade and diplomatic personnel to those with advanced life. Small planets, moons, and asteroids are the best because they're resource rich, minable, and we don't have to deal with existing life or an existing civilization.
Yep, the problem with this video is it assumes that we need to get to the destination quickly. If we were able to mine resources in space we could theoretically have a multi-generational space ship. Give it whatever time it needs, 100 years, 200 years, ect.
However I think if we were able to live in space for a really long time we may not even need a planet and could just live in space. But of course there are benefits to living near a planet system.
Additionally the video commented on how we wouldn't be able to established trade routes if the distance too that long to conquer. But there isn't any reason the colonies couldn't be independent from earth and our solar system.

I think something that could be said about the Fermi paradox is that perhaps there has simply not been enough time in the universe yet for any civilizations to have developed Interstellar travel. Perhaps it has taken this long for the heaviest elements to have been created to allow for technological civilizations in the first place
Maybe. An even bigger problem to me, though, is the highly anthropocentric notion that technology is somehow inevitable. And it's not, as every other organism on earth except humans demonstrates. Orangs have been here as long as we have or longer, yet still no language and no tech. And now that we've spent the last 75 years making absolutely sure that the rest of our rather enormous solar system is utterly sterile the idea of ubiquitous life is starting to seem a bit absurd. It is so sterile in fact that we are now reduced to hallucinating about floating organisms in Venus' atmo, buried organisms on Mars and ones floating in the dark in subsurface oceans on a few icy moons.
Not saying that's impossible or not worth examining, just that we were actually thinking a century ago that there were advanced aliens living on Mars. How far the fantasts have fallen! We could see their canals, I tells ya!
Yes. Everyone who thinks there is a paradox because we don't see aliens doesn't understand how far apart everything in the universe is, and how slow the speed of light.
What’s even more scary is that it has taken us 4+ billion years to get to this level now, yet one meteor strike could wipe all that progress away.
I think that’s part of why we may never develop anything capable because we would need a massive amount of time coupled with the hope that WE also wouldn’t have destroyed ourselves.

They are here for a long time. The Pentagon admitted it in congress. Fermi is no longer a paradox
We've only developed modern technology in the last 150 years, and we've made some impressive progress in that time. I do agree however in that in order for us to solve the problem of interstellar travel, it'll take probably thousands of years of human development to break through barriers of our understanding of what is possible. But then again, it's not like we haven't done it before. If a modern person were to take some of the technology we have today and travel 500 years into the past, they'd be burned at the stake for sorcery. On the other hand, what if there isn't a way to break the speed of light or to alter space around you to travel FTL? I guess that's always a possibility, that in fact the vastness of space will forever remain something pretty to look at, but not something humanity will achieve. Only time will tell, and no one alive today will be able to answer the question either way.
Or the scientists working on nuclear power ion propulsion or laser sail technology make a practical drive powerful enough to launch hundreds of probes from the moon to adjacent star systems. We may not get there this century, but there's no reason we can't have probes on the way by then. Exploring the galaxy will of course take a lot longer, possibly a million years, but that's not never. Basically we just hop from one star system to the next until we run into friendly aliens to trade with.
@ApplesWithPeanutButter that's why we should start with nuclear powered ion drives and laser sails. It doesn't get us to FTL, but it can get us to the next star system 4 to 5 light years away. We don't need to travel a thousand light years to a star system when there's one less than 5 light years away.
I am alive and I saw what can only be described as a starship!
This is an idea that proposes that technological progress must be continuous and infinite. It is a faith that forgets how nothing we have done in the past is remotely like interstellar space travel and physics is not cooperating in this matter. Breaking the sound barrier, or flying or crunching digits with a device are simply not comparable to interstellar travel. We worship tech as we once worshiped fire. Fire has its limits. So does tech. We were supposed to have space colonies by now. We even could. But we don't. There are reasons why.

Honestly I would be perfectly content with visiting the Moon and colonizing Venus. I once did an original sci fi story about a man who worked with thousands of other people to terraform Venus. However instead of making Venus the same as Earth they instead created an entirely unique environment and biosphere that humans could adapt to over time. If I could be a part of something like that it would be a dream come true.
When the Russian space agency sent a probe to Venus, several decades ago, it took our only known surface pictures of Venus, for about a minute or two or three before the very hot surface of this planet melted this USSR probe. The average temperture of the COLD SIDE of Venus can melt lead.
Well hopefully humanity can adapt to a Venuisian biology fast due to the climate crisis this little blue speck can become another Venus.
I don't think that humanity will last another 150 years. No one is willing to give up their gas powered vehicle and the government is not doing enough to combat the environmental problems, we will not find any miracle that will take carbon out of the atmosphere or clean up the environment, sorry to say it but that is a sad fact.
Venus is a poor candidate for colonization. The 90-atmospheres worth of crushing pressure at the surface, carbon dioxide atmosphere, sulfuric acid clouds, and 800-degree Fahrenheit surface temperature are just the tip of the iceberg. The real problem with Venus is the lack of plate tectonics.
With no outlet for the planet's internally generated heat through volcanism and subduction fault lines - hallmarks of plate tectonics here on Earth - that heat builds and builds. Eventually the entire surface of Venus, no longer able to contain the heat, turns molten and is completely resurfaced every 500 million years. Over the course of 100 million years it cools enough to re-solidify. Then the cycle starts all over again.
Mars is not without its challenges, too, but they are far more easily surmounted than Venus' will ever be.
No point in messing with Venus, too close to the sun and it will die out thousands of years before the earth does.
Why would you be content with a climate destroying trip to the moon to fulfill your jollies ?
Seeing the advancements of humans in just the last 200 years. Has taught me to never say never when it comes to us as humans.
Ok this is a bit if a misconception, there is rest mass and relativistic mass. The object accelerating doesn't actually gain mass. It gains momentum, a 1kg mass traveling at 1c would have a momentum of 299,792 kg m/s (momentum is p = mv).
The error occurs because E=mc^2 is on useful for a mass at rest, not a mass that is in motion, for that you need thfollowing equation.
E^2 = m^2c^4 + p^2c^2
I think it's the difference between gravitacional mass and inertial mass that is usually the same in non relativistic scenarios. We can say that its inertial mass has augmented however measuring against gravity will give us the same result. The question is, what do we mean by mass.
These assumptions that we will simply Rocket our way into space are what make it impossible. I have no doubt that trying to propel a craft to near light speed is impossible. But, the math for a warp drive is being worked out, and the more they work on it, the more likely it seems. A warp drive is warping a bubble of space, the ship inside the bubble is not actually moving. So all of the math around relativistic speed does not apply.
@@alphagt62 well anyone who has a marginal understanding on the topic knows that you cannot simply rocket yourself to the speed of light.
@@sgtjonmcc exactly, I believe I said that,
@@alphagt62 Yes, the Alcubierre Drive (space warping) has been shown to be feasible; at least theoretically. The problem isn't whether or not space can be warped; all indicators point to it being possible. The issue is the amount of _energy_ required to do it. It's several orders of magnitude beyond what we're currently capable of harnessing/building. Think energy on the scale of a black hole.
There was no mention of "generation" ships where the original crew doesn't reach the destination but their children or grandchildren do. People would be born, live, and die on board the ship never knowing what it's like to set foot on a planet. There are many technical challenges to be over com before any such journey would be attempted, but that's what humans do; explore the unknown.
Saying it will NEVER happen is defeatist language. WE may never travel amongst the stars but that doesn't mean a few generations from now, we won't have the technology to do it.

I found it helpful to actually do the calculations myself. Consider a light year to be 5.88 trillion miles away, (Alpha Centauri is 4.27 light years away), divide by the speed you’ll be traveling at, in this case 38,000 mph, divide by 24, then divide by 365.25 and you’ll get 75.37 thousand years. The calculations approaching light speed is beyond my grasp, so I’ll take your word for it. Still, I’m quite amazed at the number of people who want to affirm the possibility of traveling to Alpha Centauri. I think this is quite common, though it flys in the face of math and science. Of course we the living will never know for certain if this is actually a possibility, but I find it strange that there is no sense of human limitations here. And then I strongly question why we would even want to venture this far when our real concerns should be here on earth. I’m wondering if there is an inverse relationship between faith in technology vs faith in our humanity to address the problems we have here. In other words, are we inordinately caught up in the possibility of space travel that we would choose to abandon our responsibilities here on earth?

They only true thing about this video is that lightspeed is impossible. Warp speed and worm holes are the cheat codes to space travel.
Apologies for the late reply - the video just showed up in my feed…
Why would we want to do this? For the same reason we want to do everything else: to see if we can… humanity is inquisitive by nature. It is why we are (or at least, we believe we are) at the top of the food chain, and the dominant species on our planet.
Imagine we discovered that, in less than a decade’s time, a huge object was almost certainly going to impact, and destroy, the Earth, and there is no known way to stop it. Yes, there would be people working on ways to avoid this outcome, but surely this would also be incentive to find a way to get to a new world, or find some way to save everything unique on the planet?* If this does not compel every nation to come together, and work towards a solution, then nothing will, and I guess we don’t deserve to be saved.
Perhaps we will never have the incentive to do so. I certainly doubt any real effort would, or should, be made, until we have sorted out all the problems around the world, and we all live in a utopia. Unfortunately, such a goal does not seem to be high on anyone’s list of priorities.
Hopefully, wiser, and more intelligent, minds will one day prevail, and we get our collective problems sorted. Then, perhaps, we can turn our attention to the stars.
Cheers,
* Most likely, we would look to set up a colony on Mars, as it is close (in astronomical terms), and we have already carried out preliminary studies of the planet. We won’t save everyone, or everything, but humankind would survive. Of course, once we were set up there, I suspect we would then start looking for ways to move to more accommodating environs, on other worlds.
I don't think finding life on other planets is the the goal......having the ability to leave our solar system to find them is.
yes, it would be even better to find "good for us" uninhabited planets cuz it would be "rude" to move in on inhabited ones, even with lower life forms, but maybe microbes would be an exception, if we don't catch a "severe cold" there! ;D

Well one thing's for sure. It won't happen in my lifetime. Or the the lifetime of anyone currently on earth.
So true.
why so certain when the first human to live to 1000 may already be alive - who is to say how much human lifespans will expand during the next 10, 20 or 30 years. At the rate of our understanding and progress it is reasonable to assume there is indeed a possibility that we will reach the technological capability to extend life expectancy in the near future - the question is how can we manage over-poplation if we do so.
given how much has happened in just the last 200 years. We really can’t say something is never possible this early.
Yes we can. Everything has a limit. People just WANT to believe these things are possible no matter how much the universe and science is telling us it’s not.
This is just wrong.
It's E=mc. Not E=mc^2.
C-squared is absolute absolute acceleration of the mass.
E=mc equals Energy can be neither created nor destroyed, only transformed. Acceleration is what transforms energy.
Newton's Laws of Motion.
An inertial frame is one in which acceleration comes from an outside force.
A non-inertial frame is one in which the object is accelerating itself. A rocketship is accelerating itself. As acceleration increases, its overall mass decreases. There is no more propelant left in the fuel tank. Hence, E=mc.
So now your ship is drifting in space. Same as a sailboat on a calm day.
Newton's 3rd law. For every action, there is an equal an opposite reaction. The spaceship can only go as fast as mass can be accelerated in the opposite direction. F=ma -> ma=ma.
Mass does not increase with acceleration. F=ma/E=mc. Mass is converted to energy to create acceleration. Photosynthesis. Photonic energy is converted to plant matter with deceleration.
Cold water has more mass than hot water.
Acceleration does not increase mass.
It’s scary to believe we are basically stuck unless we discover something huge that changes physics
Scary? Or a relief? The scourge of humanity is currently contained to Earth, whew. What's scary about that?
Uhhh not true. There’s definitely ways to travel interstellar we just aren’t there yet
@@lionelmessisburner7393 we’re never traveling to another star. Modern science acting like false religion did in the past. Delusional
I find it much more scary that because of capitalist greed we seem intent on destroying an environment that we have evolved to live in.
And worst, the speed of light, although fast to us, is REALLY REALLY SLOW compared to the universe. 2.5 million years just to get to the nearest major galaxy. Interstellar travel is extremely difficult, intergalactic is just impossible.
Physics already tell us that Warp drives and creating holes in space/time is possible. It requires exotic matter but it’s only a matter of time until we figure it out. Speed of light will be inconsequential. To say “never” to anything is a bit silly
It is not inevitable. Concrete was a forgotten technology. As common as it was in the Roman Empire. Once it collapsed the big projects were no longer commissioned. Concrete was no longer necessary and the method was lost. If someone asked me to make a computer chip, or even a diode, I would not know where to start.
@@markharmon4963 Those of us who have made a "foxhole radio" know how to make a diode, look it up for fun experiment. Making a point contact transistor, the first one made in 1947, is pretty easy too. Concrete was rediscovered after a thousand years because recipe was written down and found again, so education with publishing and distribution of knowledge all around the world is important and a kind of "insurance"!
@@RWZiggy In order to create all of these things requires an economy large enough to support all of the supporting industries. That was my point. There is a window of opportunity here to be space faring.
@@markharmon4963 The Romans could have made the diode and transistor I mentioned.
@@RWZiggy Of course they could, if they new how and enough people new how and enough food clothing and housing could be supplied to these people who do nothing except study and practice how to make these things that are useless unless there is an electrical grid to supply enough power to make them by the millions so that an industry can be created to support micro processing. A library full of books is useless without the background understanding to interpret them. The space industry is languishing in mediocrity. This war in Ukraine demonstrates that the aerospace industry exists to sell weapons, not to explore. If we want to become explorers of space and the deep sea we should do it because there is no guarantee the future is going to provide better opportunities if the past has demonstrated space access has been deteriorating.
This is why warp drive is the only real answer to traveling the stars. In our dreams now but you said it’s not a matter of time for our speeds to increase. I think it’s true that it’s a matter of time, until we find a way to warp space. It is theoretically possible. It’s already been mathematically proven. It just hasn’t been figured out yet. Maybe in the next couple hundred years. Warp bubbles, if they can be created, negates the whole speed of light vs mass barrier. And it also should negate time dilation.
My favorite dialog line from mechanical engineer "Scotty", from the 1960's TV series Star Trek, is his telling Cap. Kirk that multiple/times of warp speeds will put us into the other side of the galaxy in a few hours is extremely funny. This is just plan "out there" and crazy/insane to even try to travel at such speeds. E = MC squared. Nothing is faster than (both) the speed of light and dark.
@@phillipmel that's a misunderstanding of what a warp drive is. The ship doesn't accelerate, but the space in its surrounding is distorted, so the ship goes forward.
the math they use to prove a warp drive is all made up the original nonsense. I wouldn't put much stock into any theory that requires the use of constants that are defined as, "defined by definition". lol. they say that all that bullshit is proven because someone stuck a clock in a plane and had it go up and down really fast but they don't really know why that clock reacted like that
@@qweqqweq2090 Don’t really know what you mean by, it was all made up. If I made up you mean a theory then yes it’s a theory. Theory doesn’t become a fact until it’s put into practice. Which is what NASA and some other organizations are working on right now as we speak. The original theorem said that a warp drive would need all the energy in the universe in order to power it. Which obviously is more than impossible. But over the last decade they’ve managed to narrow it down to the power of a sun. Which is still impossible with today’s technology. But that is still a huge breakthrough and step closer to making it reality. Right now the only 2 things keeping warp drive from working is the need to generate power the equivalent of a sun, and exotic particles. We’re already creating exotic particles. But it’s way to expensive to make enough of it to use in an engine. Warp drive is not a sure thing. It may never be realized. But the math and science is there. It’s just that technology isn’t there yet. So to say that we will never ever explore the galaxy or the universe, that definitely may be true (for us, the human race. We could all die out before we advance that far), but it also equally may not be true. Because the technology is possible, the question is will be create it before we become extinct. Only time will tell.
Sure, Just like we would never fly, break the sound barrier, land on the moon, create AI, make computers the size of a phone that are more powerful than a 1970 room full of computers, and travel to the deepest part of the Ocean.
Just a silly premise. You don't need to travel at light speeds to colonize the entire galaxy. That's the point fermi paradox: We know for sure we a civilization with our current technology travelling at sub-light speeds could easily colonize the entire galaxy within a few hundred thousand years. We don't detect those civilizations therefore we are most likely the first such one.
That or:
1. Civilizations wipe themselves out before they became interstellar.
2. They have a level of technology that we are not able to detect as yet
3. This universe is a simulation
4. They don’t want to be found and would rather observe our primitive society until we come to maturity
To be "the first such one", we first would need to be "such one", and we are not. Humanity will die on Earth. Yes the fact that it would take a long time by human lifespan standards wouldn't make it impossible. But it would still not be worthwhile for anyone to do it.
Getting through the Ort clouds billions of planetiods without crashing into one will be an achievement in itself.
Do you know how far are those objects? Ort's cloud or the asteroid belt are not like in cheap sci-fi films, rocks that are so close that a spaceship should navigate through them, they are so far apart that if a spaceship passes, if there is an observer in that ship, that observer will have a hard time seeing more than a couple of rocks.

I'm afraid I agree, unless we find a way to open portals or wormholes, that is if they even exist. Someone made a graphic that shows the size of our 200 light year diameter radio bubble and it's place just in our own galaxy. It's pretty tiny, and it's 100 years of radio waves at light speed in all directions. It took the Voyager probes like Forty some years at 30 some odd thousand miles an hour to reach the limit of our little solar system. Not even seeing us colonizing Mars, honestly. Too many barriers to conquer and think of the vast resources that would be used just to get a few humans there so they can go hide in caves, away from solar radiation.
then how are those ET crafts getting here? like the ones Fravor saw, and that's only one sighting there are countless others.
I think the thought that we are nowhere close to the most intelligent species makes people uncomfortable.
cognitive dissonance or something.
I have seen them too and know SOMETHING is getting here. they have been seen since before WW2 and sightings increased after the first atomic tests.
but don't believe me, go back to burying your head in the sand where you feel comfortable.
I'm sure the world's governments are trying their hardest to reverse engineer these crafts too, and wonder how far they have gotten. as soon as one of them does it will not be pretty. I hope humanity can get along before that happens otherwise ET is going to get a front row seat to our self destruction.
@@LisaAnn777 I don't doubt that other alien civilizations are able to get here, I agree with you there. I just don't think WE will be able to do what they are doing for a long time, if ever. As you said, we're too concerned about 'other' issues right now that pale in comparison.
My god - so those same old radio favourite pop tunes they’ve been repeating for what seems like eternity will literally continue for eternity 🙄
well of course it seems impossible now..but I'm sure millions of years from now humans will accomplish many things we thought were impossible. I mean look at people who thought it'd be impossible to fly and the first airplane was invented in 1903. Then you fast forward 94 years to 1997 and we have robots on Mars. No one would have ever thought that was possible many years ago. I wouldn't be surprised if the first humans to land on mars happens within the next 100 years. Not to mention humans will continue to evolve biologically and technologically to reach greater heights than their ancestors could ever imagine. If you could bring someone back to life that lived let's say...200 years ago they would probably be in awe of the difference in technology. Imagine the technological improvements we've made the last 100 years and try to picture what will be accomplished even 1000 years from now. We know so little about many things at the moment...but I'm optimistic that we'll reach the stars even if it takes millions of years. Humans love and fear the unknown but we always strive to accomplish something that's deemed impossible. You should also look up NASA dragonfly where they'll send a robotic rotorcraft to Titan - Saturn's largest moon in the search for origins/signs of life.
@@PineappleBaconPizza I appreciate your optimism, but I don't think we'll make it that long...

I'm glad to see you mentioned two problems with near light speed interstellar travel that are often ignored; the possibility of catastrophic damage to the spaceship due to collision with interstellar matter, and the large difference in the amount of time that passes between the space travellers and their home planet (and destination). And you also correctly noted the answer to the Fermi paradox; the fact that aliens haven't visited us doesn't mean they don't exist, but merely that they (like us) cannot travel the vast distance from their planet to Earth. I would add that even if someday we discover Einstein was wrong and there is a way to travel faster than light and aliens developed that technology, how would they know about us, and why would they decide to visit us even if they did? Our galaxy is a huge place and here are billions of planets in our galaxy alone. It is very unlikely aliens would know we exist and even if they did they probably have more interesting places to visit.
Yeah,even interstellar dust would destroy the ship completely in a few minutes at light speed.
I think if we were to find the ability to travel the distances the first place we are heading is where there might be other life. It seems to be rare, certainly the search for Habitable planets alone would bring them to our solar system at some point, Earth is a jewel in a Galaxy or rocks. We can discover big planets around other Stars I bet people 1000 years ahead of us can do much more.

@@jonothandoeser it’s not rationally possible with our current technology, and definitely won’t be possible if everyone has poopy pants can’t do it attitudes. Miguel Alcubierre’s theoretical warp drive utilizes a soliton warp bubble to move at speeds 10x the speed of light. If we can create a warp bubble inside a warp bubble, it may theoretically be possible to travel at 100x the speed of light. From what we now know, we probably will not get the energy needed for this until we can use self-replicating AI bots to create a Dyson sphere. We are close to nuclear fusion reactors as well which could be utilized as energy for the soliton creation in warp drive. Imagine another 1000 years of technology advancement. In the 1800s we were traveling by train. Now we have rovers analyzing Mars’ surface.

Yes, JB, good comment. There's not anything that we could gain nor learn from space travel that our probes have already told us. The super-far distance that both Voyager space probes have gone verifies this fact(s): The out-of-our solar-system region is mostly a void of dark matter with very little resistence to radio signals (from the Voyagers) through this open-matter. It has so little of what we would regard as molecular density, or even anything other than darkness, void and vacuum, that taking any trips by humans would be pointless and suicidal.

Most correct. Interstellar travels are simply impossible, even for more reasons than are mentioned in this video.
Wrong. Ur too stupid and close minded
Bs tell that the aliens that flying there craft in our sky’s the government and military even admitted it’s not man made and have no idea what they are
1. Never say never. Never is a longer time than you think.
2. In 1900, if you said in the future we'll have easy access to all the information in the world in your pocket, they'd think you're joking. If you told someone in the year 1000 that we'd have giant metal birds to fly across the same ocean many people struggle to survive for months, in less in a day for a few hundred dollars, they'd think you're crazy.
3. I'm not saying now, I'm saying eventally. A few thousand years, maybe.
@@ericgolightly8450, we're talking about two different categories. You're talking about "not-yet-possible" and I'm talking about "not-possible-at-all".
In the year 1900, if I had told them that 80 years later high-jump over 6 meters would be possible, just by means of a long rod, they would think I was joking. That's something that was not-yet-possible at that time. However, if I had told them that several decades later a person would jump 600,000 meters by means of a simple long rod, they would think I was crazy. And they would be right, because such an enormous jump is not-possible-at-all.
Interstellar travels are not-possible-at-all even for more reasons than are mentioned in the video. They are just a figment of imagination on the part of some quasi-scientists, whose task is to distract people from important things by engaging their minds in things that are not only impossible, but also stupid. And it's not just intergalactic and interstellar flights, because interplanetary journeys are impossible, too. It is questionable - albeit maybe not fully impossible - for people to reach the Void above the last layer of our atmosphere.
If you are a) intelligent and b) objective, you'll be able to figure out yourself at least some of the problems that make those flights impossible. All you will need is just a little knowledge and a high quantity, of logic. Actually, even a 15-year-old intelligent boy would figure it out, if he only knew the basics about the Universe, the most crucial of which is the fact that all bodies there have always been moving. Which means, there is no chance for us to know WHERE a certain planetary system is, given the fact that it doesn't stand still. If it is 50,000 lightyears away from us, it means that it WAS there where we see it 50,000 years ago. But during those 50,000 years it crossed a large distance, and we can't know in which direction. If it is moving away from us, it may now be 60,000 light years away. If it is moving towards us, our super-fast starship may collide with it. Besides, we can't know if the spot where it used to be 50,000 years ago is empty now, or taken by another object - a black hole for instance. There is no way a starship could travel faster than it is needed so as to detect and dodge possible obstacles on its trajectory. If you travel with the speed of light - as if such a thing was ever possible - you could never dodge a body that crosses your way, so there is NOT A TRACE OF A CHANCE for a starship to reach any destination, because it will be destroyed very soon after it accelerates.
Just a little basic knowledge, a good portion of intelligence and a high amount of logic.
People will be laughing at this comment in the distant future.
We could reach alpha centarui within 80 years on a nuclear Shockwave generation ship.
20 years with starshot project
Great. Then we can send young 25 year old astronauts out to space and they can start getting to work when they are 105.
@@Yora21 lol better idea? No? Bc there's not a better idea. It's called distance and sacrifice. Yeah we can send dumb probes but that wouldn't be colonization would it?
Advancements in relationship to time have compounding effects. Meaning the time it takes us to make great discoveries not only shortens but as the frequency of discoveries increase so does how impactful the discoveries themselves are. What we make advancements on in 10 years will dwarf the previous 50. The next 50,000 years will make the previous 50,000 seem like nothing. Imagine bringing just a simple mirror back 50,000 years ago lol.
the faster you travel, the more catastrophic is the impact with a grain of dust... imagine hitting a rogue planet, because you don't see it early enough to avoid it!
We need a force field
@@paulallen2680 you need realism. "Force field" would only act at most with the speed of light... but what of a moving particle? How many deflection beams would you need for an asteroid field, and how much power would you need to create and consume and at what rates??!?
every mote of dust could fly right through your ship and crew, from bow to stern, even right through your power source.
@@brookestephen the thing is if some civilization is able to travel that fast then they would probably be able to figure out something about that. We talk about fantasy technology but only about the one we are concerned with. Its reasonable a civilization of that caliber will have way more techniques of dealing with stuff we yet cannot thing about
Build the spacecraft like an arrow. Have like 100 solar sails with self-repairing material, detectors, deflectors, pulverizers and incinerators at the front of the spacecraft.
This is a compelling video, but I do have a qualm with using the Fermi paradox as definitive proof that no civilization is capable of interstellar travel. The Fermi paradox asks the question of why we see no technological signatures at all, not just signs of an interstellar civilization. That includes radio signals, the presence of certain chemicals in planets' atmospheres or signs of certain large-scale structures such as Dyson spheres that a civilization colonizing its solar system might be expected build. None of these things requires the civilization have faster-than-light travel, yet we have not seen any of them. So we don't have conclusive proof of any type of extraterrestrial technological civilization, but since our own civilization exists we know they are possible. Therefore we can't use the Fermi paradox as a basis that interstellar travel is impossible, because using that line of reasoning there are NO other technological civilizations besides our own period (and if by chance that's true, that renders the argument moot, because there's no other civilizations to compare) . Now, if at some point we do find signs of ET intelligence but find it appears they have not traveled beyond their own solar system, then this premise holds much more weight, but for now I don't think it's the "nail in the coffin" argument against interstellar travel.

You're correct, that's not the "nail in the coffin" argument... physics is.
We weren't able to scan atmospheres of exoplanets before the James Webb telescope and the Dyson sphere is just a theoretical concept.
We are already traveling among the stars. We just need a rudder.
Edit: a really big rudder...
Being 70, lifelong learning, understanding, observation, experience, re-examination 24/7 365.
The cosmos is not a vacuum, everything in it is weightless, the place we call earth is the only one, conscious cognosentient beings (humans) are earth specific, no conscious cognosentient being is able to reproduce outside our earth specific environment and survive without total metabolic breakdown and turning into a boneless mulch where conception, birth, child growth, evolution and development would collapse and even if a 'technological' breakthrough could extend life 'space specific' (outside earth specific environment) there would be no chance of a return to 'earth specific' environment without gravity crushing the returnee to a mulch in re-entry.
Astronaut physical anomalies have been measured and have already been found to be catastrophic to the whole body, THE WHOLE BODY, not bits but the WHOLE.
GET OVERIT, EARTH IS ALL WE HAVE.
What about ROBOTS, A.I. is the retort, OK......that's not conscious cognosentient beings in exploration of the cosmos, that's TOYS IN SPAAAAAAIIIICE!......
I despair
I've seen people claim with certainty that "Some day, surely, we'll achieve the engineering needed to reach light speed!"
But how is humanity supposed to overtake a speed so fast that matter becomes almost entirely indistinguishable from energy? Humans die from seconds of exposure to gravity six times earth's gravity. These would involve forces HUNDREDS OF THOUSANDS OF TIMES Earth's gravity.
There is too much radiation and too many little tiny rocks to blow your mind.
The reality is we don't need to reach light speed to become interstellar. If nuclear powered ion propulsion can get us between 10% and 20% light speed we can reach neighboring star systems in less than 50 years, and we could close the gap to a couple of decades.
We don't need to send people right away. We can send lots of probes that fly by and take pictures, then robots that go into orbit or land. That means it will take about a hundred years for each star hop, but in one hundred thousand years that's a lot of star hops, and a lot of the galaxy and nearby stars systems explored.
@@vidyaishaya4839 If humans are able to accelerate to 20% light, we can only travel at 10%. The remaining 10% has to be used for de-acceleration. A very close star of only 100 ly would take a 1,000 years. Think of all the changes humans have done in the last 100 years. Radiation, micro cosmic partials, a grain of sand, mechanical breakdowns, air leak, and a 1000 years. The human body deteriorates in 0 g, eyes n bones. If we start modifying human dna, we will be no longer be human.
@@oldmech619 it will take a while to speed up and slow down, but not half the trips. That's why individual trips will be less than 10 light years in length. A trip of 100 light years would involve 10 to 20 hops, and would take at least a thousand years. Interstellar spacecraft will be huge, capable of carrying up to a million people, but thousands at a minimum. They would have to be self sufficient, and large enough to be a world of its own. It would also need to carry enough resources to begin a new colony in the new star system. While most of the people would leave the transport, enough would remain to go to the mext star system and populate up during the journey.
@@vidyaishaya4839 Sound like an exciting adventure. I can’t wait any longer.
If you tell someone 200 years ago that you’ll be able to go across the world in a matter of few hours… they would probably think you’re insane … Kind off how we thinking about interstellar travel right now
It's good that we learn from the past but let's not get too stupid about it. Something's just aren't possible to have.
@@garysnow1475 must I remind you where we are on the Kardishev scale? We don’t know what we don’t know
Having an interstellar civ. and simply travelling to other stars are not the same. None of these disprove ships travelling below 0.1c to other stars. But even at 0.1c trade between stars can very well happen. Such trade would only involve extremely basic objects such as energy, water, hydrogen, anti-matter etc. and in large bulk. These kinds of trade would happen in simple barter system and won't involve any currency but such trade can happen by means of large generation ships travelling between stars even at below 0.1c. So yes, you are wrong in saying we would never travel among stars and you are wrong in saying that humans living in different star systems cannot communicate in any meaningful ways, but you are probably right that there will be no interstellar govt. But then again the future can always surprise us so best to include a probably in your "X will never be" predictions.
“The word impossible, is only found in the dictionary of fools”
-Hans Reinhardt…The Black Hole
depends on a few questions:
1. what you mean travel, since regular travel mostly out of the question, at best a normal human will move from star to the next, and that will be an achievement by itself for the person.
2. what we consider under human, if we solve aging in one of the many potential why (mechanical replacement, de-aging biotech, mind transplant) than suddenly a ten year trip is no longer than a year long voyage was for the people in the age of colonization.
3. how far we willing to move from humans, a digital mind on a computer by definition ageless, and a computer can be accelerated much more than a human, so faster trips for near limitless time, no issue with actual proper travel. And if it is a program anyway, we can just send it without any issue, more of copying but still a version of the mind will travel.
4. we, as in humanity, the race, not the individual, sleeper ships, colony ships, or seeder ships are all possible with current tech, and will be more and more possible in the future. with fusion (if it ever arrives) we can simply create self sustaining colonies, which if they decided just travel among the stars, every century or two apart, they arrive to a system, replenish whatever they need exchange culture directly with the systems local population, and goes on.
So yes, we will travel between the stars, just do not limit your imagination to what sf tells you, they are bland to what the future will be.
Guy, he addressed just every single aspect of you comment, which you choose to ignore. I'll add another, money. Who's going to pay for your sci-fi fantasy, and for what purpose? We're talking about staggering sums of money here. There is nothing worthwhile in what you say to equal that.
Unless you're referring to some hidden, suppressed form of technology, then I would say that no, we don't currently have the technology to develop/launch seeder ships into space.
The problem with fusion technology is that it produces a form of energy that we still can't directly harness. It would still need to be converted into pressure from steam. True, it's a virtually inexhaustible form of heat energy, but is not usable with current technology for space travel, let alone interstellar travel.
You would need an endless supply of water to convert to steam. And even if you were able to develop a closed loop system where the steam is collected and returned to liquid state, there'd still be losses, with the strong possibility of something breaking down. It's not a reliable system for travelling tens or hundreds of years in space.
@@robinstewart6510 of course, why go to the moon, when people in africa...
Luckily not everyone is limited like you, otherwise we would still be on the tree.
@@Aquascape_Dreaming The heat plant part of the fusion power plant is very well done, since it is used in every heat plant on the planet, in a closed loop, you do not need any external water for that. You need some fuel for the fusion plant (and that will be tricky to source, depending on which variant can we work, if any,) but that will be very small amount compared to the entire system. For the fusion drive, yes, you still need something to exhaust, but much less than with current rockets (even the least complex fusion drive ideas gives us Isp in the thousands, compared to the chemical fuels 550 or less) not to mention that with ready supply of energy you might just go for an ion or plasma drive, it will be slow anyway, but gain the benefit of 30K+ Isp.
@@thorin1045 .. And luckily not all are foolish like you. Yes, why go to the moon? We spent many millions with nothing to show for it. We already knew what was up there. I'm all for reasonable spending to help others or "improve mankind," but am tired of the government wasting money (backed by those like you).

Let 'em go, and see how it works out for them. Problem is, we may never know because they'll be too far away for their message to get to us. Our language may be indistinguishable to them by then.
If physics works definitively against us for interstellar travel, I believe we'll be able to download our consciousness into super computers...buried underground and able to "live" as long as the earth remains intact. A perfect world of our own making. The technology to do that seems more probable than far flung space travel. I would guess that it may be possible within the next two hundred years considering how quickly we are advancing in that area.
Perfect example: ^^^ Our imagination is what leads us to achievement.
