The possibilities within space travel never cease to amaze. It certainly intrigues me to no end.
wildfoodietours6702- Yep! I think about the fact that the first manned, powered flight was in 1903, but by 1969, Man had landed on the Moon. Impressive progress indeed. During that period, higher altitudes and higher speeds and longer ranges were achieved. The speed of sound was exceeded, a “barrier” that was thought to be impossible to cross. But all of these things were achieved by finessing our approach to those environments, not by trying to alter the environment itself. At some point, probably with the help of AI, there will be an epiphany that will lead to an unprecedented scientific breakthrough in which the power and the ability to achieve FTL travel will be discovered, right within the forces of the Universe itself. 63 years from Kitty Hawk to the Moon. From today to FTL travel? I say 30 years, Max! And that’s my most pessimistic guess.
It always BLOWS MY MIND, why anyone would talk with a astronomer about propulsion.....ß
Alpha Centauri pal, not Centuri.
I have a hard time containing myself when it comes to space travel...I regret nothing...space travel is an awesome opportunity. Wether we are able to space travel or not I refuse to give up hope.
M go
I’m 😅
They will travel through space some day but we might never see it Like someday they will solve Black Holes and find a way to escape the event horizon.
We can conquer death and learn how to live forever. The heavens are ours, we each can have our very own star. What we have here is beyond belief, our devil is money.
Me too
Wouldn't being stuck on a generational ship have severe mental side effects? I would imagine depression/anxiety and/or other problems would develop. Humans can't stand each other on this planet...how could they not kill each other when trapped together on a ship for generations?
This mission would be impossible. Suicidal sabotage or infighting would destroy the ship. It would never reach its destination
You're exactly right. I agree with you 100%. A good and obvious point which many seem to easily to forget or not consider.
Look up "Paradises Lost" by Ursula K. Le Guin, first published in 2002 as a part of the collection "The Birthday of the World"

@@dennismenis3215Hermes be like 'ragedom'
We are in a ship(earth) and we kill each other.
You can also go the theoretical route of hibernation. If we were to figure out aging and hibernation it would be possible to travel to the closest star using conventional technology and 10% speed of light.
Hibernation does not prevent aging.
And when you return, everyone you know is dead and everything you know is gone.
@@brandonflorida1092the price you pay when traveling interstellar
Everything is impossible until one day it happens.
What man imagines,he does.
Exactly. Never tell humankind that something is impossible to do. We will find a way to do it, JUST to spite the person who told us we couldnt do it.
@@nephalos666 Thanks for the reply man.
@@nephalos666 h6y
And what God imagines… Is ..
No, not everything is impossible. However FTL travel is 100% impossible.
It's all about thinking outside the box. If there are indeed certain limitations and unbreakable laws of physics that prevent us from travel away from earth of any significant distance, then ways to "bend" the rules need to be discovered. The Alcubierre drive is an example of this, though of course it is purely theoretical.
This is a very simplistic example when compared to space travel, but relevant in terms of making the impossible, possible through bending the rules. A Volkswagen beetle simply is not going to beat a Porsche GT3 in a quarter mile drag race, it is impossible assuming of course there are no modifications allowed, both vehicles are driven by skilled drivers, and both vehicles function properly and do not break down or crash. However, this was achieved when the rules were bent and the playing field was changed from 2 dimensions to 3. A beetle when dropped a quarter mile in the air from a helicopter will cover a quarter mile of vertical space quicker than a Porsche GT3 can cover a quarter mile of horizontal space under its own power. This was done by our friends at Top Gear. Again very simple, but completely changed the result when an extra dimension was added to the equation. Could the same be true in space if and/or when a higher dimension were to be discovered and possibly manipulated? A rocket powered ship is only going to go so fast, but if there were to be a "way around" through a higher spacial dimension could this be exploited?
What's impossible in one dimension is not only possible, but practical in a higher one. On a 2D plane you can only go back and forth and side to side...up and down is not only impossible, but can't even be conceptualized by an entity living within that 2D plane. What impossible movements might we discover in a 4th spacial dimension, or higher? Traveling to another star system might be like walking from your living room to your kitchen. We would never know if higher dimensions are not unlocked. The problem is unlocking them, can it be done, and do they even exist? Some scientists think so, but again it is purely theoretical.
i find this video to be very informative and thought-provoking. The author provides a clear explanation of the challenges that we face when it comes to interstellar travel, and the potential solutions that have been proposed to overcome them, including warp drives and generational starships. The discussion of the ethics and practicalities involved in a generational ship mission is particularly interesting, and it raises important questions about our responsibility to future generations. The author also highlights the complexities involved in the physics of faster-than-light travel, and the energy requirements that would be needed to make it possible. Overall, this comment provides a fascinating look at the possibilities and limitations of space exploration, and it leaves the reader with much to ponder.
spacetime does not exist, you cant bend something that doesn't exist.
eg. you are here > how do you bend what is out here > ?
I love the Daedalus-class starship from Stargate in this episode
Thats when you know you watching a video based on horseshit as its core principal.
Was thinking the same thing lol.
Almost, the engines look different and there are none on the pods left and right. Also the top looks a bit different.
Still the reason why i tuned into this video. 😎
Imagine being the 20th generation to grow up on a generation ship, just about to arrive at its destination. But when you get there, humans have already colonized. They tell you, "oh we figured out warp drive a couple of hundred years after you guys left. Sorry!"
Child
That happens in Starfield😂
I’d be fuming 🤣
It's kind of interesting that at 2:19 there's a brief flash of anaglyphic 3-D (the red/blue kind used in the old 3-D comics). A Caltech colleague of mine once published an anaglyphic 3-D map of nearby galaxies, but I don't recognize it in this brief flash.
🤔 huh 🤔
For now We are hopeless for Interstellar travel, but let's stick out for couple of Centuries and it might change. We might get some help from our galactic neighbors.
Bub….there’ll be precious little left to explore space with after the war!!!
@@drjojo5551Which war?
We already have the tech according to Bob Lazare
In science we say extraordinary claims, requires extraordinary proof. So far we do not have the proof. @@coreyfreeman6226
We could probably already have this stuff sitting in a secret underground military base 😂
I would like to know about warping space. If the closest star (Proxima Centauri) would take 7 to 10 thousand years to get there normally, could warping space make it 4 years? Now, in that time vector of warped space, would a planet still be on normal time and advance 7 to 10 thousand years?
So in other words, will time dilate if such a method is used? It is believed that no, it would not, because by using such a method of travel (warping the plane of space, wormholes, etc) there would be no effect on time because you are not reaching relativistic speeds, you are simply taking a "shortcut" at slower speeds. Time is only effected when high speeds come into play, or you get into close proximity to a large gravitational force (e.g. a black hole). A wormhole or other "bend" in space is essentially like folding a piece of paper and coming out the other side instantaneously, you don't necessarily need to go fast to get there, you just drastically shorten the distance of the journey. It is theorized that we can produce man made wormholes, but the technology needed is well beyond our current capabilities.
@digitalfootballer9032 Now, that is a good answer, but ask the experts please, like Tyson.
@@digitalfootballer9032 the issue is that we assume that space can be bent like a piece of paper, it cant and even if it could be done you would need insane amounts of energy, basically whenever they say wormhole what they mean is like a teleportation device it would still need to move matter somehow which require insane amounts of energy that we cant make, and if you would say well wormhole just has the energy and works then odds are it would destroy any ship trying to go through it
Just supposing we could achieve say 90% the speed of light, could we travel to distant planets ? I think there may well be another major problem to solve first. Space may have large voids but there is dust and probably small chunks of rock. Travelling at colossol speeds and hitting even minute particles would explode the space ship.
It’s not only dust. Also the frequency of any radiation (like the microwave background radiation, or the light of stars) increases to quite lethal levels!
On the plus side: with relativistic speeds like this everything in our galaxy is in reach. Travel times of thousands of years only apply to outside observers. From the point of view of the astronauts in the ship, the travel distance shortens drastically.
We have developed self guided Lazer missile defenses that recognize and eliminate threats. This technology will expand in future and likely be able to eliminate even dust particles ahead of a star ship. The bigger problem is there will never be a reason for a starship. It's just too far to travel and there's no payback at all. Probes can do studies of a planetary system and return a signal to earth. But that's only if we are curious about that other star. By the time we have the technology to mount a mission to Proxima we will have made the trip unnecessary from a survival standpoint.
Don't forget it would also take you 2 lifetimes to safely accelerate to 90% and then 2 more to deccelerate withouy ripping our fragile body into mush.
Possibly a spinning centrifuge type device in middle of ship that would generate a heliosphere, like Earth, of energy around the ship, like a bubble to disintegrate any solid matter in the way but Idk if it’d work on large clouds of gas to protect. I’m pretty sure we’re living in a simulation( simulation theory) any how. Universe is fine tuned for life and we are trapped on our planet. Best thing is to create individual Matrix pods and let each of us live in our own paradise
In the fiction of Star Trek, IIRC, a starship has a “deflector array” that works something like a “tractor beam” in reverse-it repels objects away from a ship in flight, like the front blade of a plow truck. That might take care of interstellar dust impacts.
As far as radiation is concerned, some sort of of electromagnetic field, like Earth’s Van Allen Belt, would have to envelop the ship and absorb the bombardment of cosmic rays so that the crew’s DNA isn’t instantly fried.
Of course, this would also take a complete mastery of gravity and inertia. Hitting the brakes at light speed would turn the crew into goo pretty quickly.
That all sounds nifty, but we haven’t a clue as to how to do any of this.
There is some technical correction which I want to do, at 0.47 the statement should be nothing can exceed the speed of light within the space ,which hold the matter because, the cosmic limit is for those entities which are within the framework of space. Space itself can move way faster than light.
I hope I see it in my lifetime. This stuff blows my mind in all the right ways.
This answered some of my most important questions. Thank you.
Imagine getting to Alpha Ventura after generations, just to find out that people back home invented warp drive and beat you there.
An then you get there and it turns out Alpha Ventura doesn’t exist, you the. you realize you were supposed to go to Alpha Centauri.
They can't. FTL travel is impossible
As explained in other videos, going faster than light causes causality paradoxes, where different observers could not agree on which of two connected events happened first and where it becomes possible to send messages into the past. If it is possible to traverse cosmic distances in less time than light would take, then the concept of causality and how events in the universe are connected would need to be recast.
I agree with everything you said, except the last sentence. Saying, "if it's possible", is like saying "if it's possible the Earth is flat, then the Earth is not round". You can't "if" an impossibility into existence without contradicting observable facts. FTL travel is 100% impossible for the reasons you stated, if it were possible, then reality is not real. But this is impossible since reality is true by the virtue of the fact that it's observed. Observations can't be contradicted by Star Trek fans who put their feelings before facts.
@@misterscollard That's a very good point. The speed of information is finite. If anything else could go FTL, then that would be the speed of information.
@@thuggeegaming659 This is curious. Certainly, the speed of information is a limit to the speed of space travel: If a person travels across the galaxy, her knowledge travels with her. If I spent some time, maybe I could imagine all of the paradoxes this might create.
"Information is information, not matter or energy"-- Norbert Wiener
I like Tyson, but he is just spewing Star Trek on this occasion.
FTL travel is not necessarily impossible, it would have to be empirically disproven in order to be deemed impossible. There are theories like the Alcubierre drive (essentially a Star Trek type warp drive) that may be possible, but require exotic matter/technology that we do not currently possess. Improbable is a better description at this time, maybe near impossible, but there is still a non-zero chance this is possible unless proved otherwise. It may very well be something that is possible in concept but could never be achieved because of human limitations. That's not to say a more advanced species doesn't, or hasn't already, achieved such a technology.

3:24
And, Neil, how do you propose to both generate and, more importantly, control an amount of energy that could alter the shape of the universe?
Isn't it the case that we need to go faster than light to cross a worm hole? (Einstein Rosen bridge) At least for classical black holes this can be seen from the Penrose diagram
No, it's not. In using a worm hole, no object would ever pass through space as fast as the speed of light. Bending space isn't the same as passing through space.
We are actually living on a generational ship. Might be interesting to utilize a super computer to plot our destination. Or maybe I have just watched too many sci fi movies. Cheers.
Yes, keen observation. Maybe we are someone's science experiment... without ever knowing.
Our Sun orbits the Milky Way Galaxy every about 226 Million years.
You have either taken not enough or too many drugs, me personally i am still in not enough stage.
1:47 Somebody explain what those little white dots streaking past the space craft are.
Good point. Sci-fi imagination, I would say.
Several hundred years ago it was a question of if and how it could ever be possible to journey to the opposite side of the earth in less than a year, and now it is done routinely in less than a day.
Question: How would traveling through a Worm Hole affect Time? Is the passage of time on Earth roughly the same as the passage of time on our Warp Drive Ship??
Worm holes don't exist. Neither do Warp Drive ships. FTL travel is impossible
@@thuggeegaming659The professor has spoken again. Don't argue with him, he got his doctorate out of a cracker jack box 😂
In theory, time should not be effected by traversing a wormhole. In concept, you are not reaching relativistic speeds as you would need to do to travel from a point in space to another point many light years away in a human lifetime, rather, you taking a cosmic "shortcut". Real scientists, unlike our friend here above us in the comments, conceptualize this as being like at a point at the end of a sheet of paper, and to get to the other side you fold it in half and punch through the paper instantaneously rather than traversing the entire sheet. There are many good videos on the subject from leading astrophysicists, all of whom know just a little bit more than Mr. Cracker Jack up there 😂
If we go beyond speed of light does time behind us go backwards?
We can't go beyond the speed of light.
Amazing theories of traveling faster than light itself have intrigued me ever since I got involved in space sciences in school.The mysteries of the study in space/time still fascinates me❤
In a sense, generational starships exist today, they are simply planet based. Collectively it could be argued that we have a goal that we will never see achieved in our lifetime (peace), but we as a species bring forth the next generation to further that goal, and then they bring forth the next, and so on and so on. The difference there is that each gwneration has its own individual goals that dont necessarily further the overall goal and in some cases could hinder it.
Nothing can exceed Lightspeed, and remain in Our frame of reference. Rather significant difference.
Thus the Einstein-Rosen bridge aka "wormhole. If one is ever discovered or made, anything traversing it would, as far as we could perceive, cease to exist and since the distance traversed would be so vast that any signals saying that they made it would not arrive in any reasonable time frame.
What if you walked backwards real fast.
Could work
I did that once... got a speeding ticket.. local police have no sense of humor.
Works every time!
Someone please I want to go back please
OH MY GOD!!! HOW DID SOMEONE EXPLAIN THIS PERFECTLY!!?? THIS MAN!!
Just asking. Can't we use light as an energy to push the space craft??
All my life I have wanted to go into space, I don't care if I travel for the rest of my life as long as I am in space. I'm just weird or something but it's my dream yet I know it will never happen.
Well it’s already commercialized. Never say never. But read Shatners experience if you haven’t. It might not be such a good dream.
You will see only darkness ,humans are not meant to be stuck in one place all their lives ,depressions and other form of mental illness could easily arise .
In space, nobody can hear you scream 😂
Humanity: "We've looked all over the universe. We've searched every planet and every star and couldn't find a thing!"
Also Humanity: "We've only been capable of space flight for 65yrs! Give us a break!"
You cannot accelerate anything composed of matter to the speed of light - period.
For me the only way is to consider negative mass in GR like in Bondi extension of GR or like in bimetric gravity. Negative mass does not exist but it can be substituted by negative energy. Negative energy exists. Casimir effect has negative energy, two opposite charges also, two masses interacting gravitationally also. In Italy there is an ongoing experiment aimed at measuring the tiny repulsive gravitational effect of 2 Casimir plates. It is called 'Archimedes' experiment and it's done by INFN and CNR.
When he was talking about star trek warp drives, he was showing a Stargate Daeddelus class battleship
That’s not how a Star Trek warp drive works. It doesn’t create a wormhole, it contracts space time in front of the ship while expanding space time behind it. It literally shortens the distance between points in space.
It flattens the space behind it pushing it forward like the ship's in the three body problem
He didn't say it created a wormhole. He said it bends space and time to get around the light speed limit.
And for that matter, they never traverse the galaxy as he suggested.
@@brandonflorida1092 Yup. Voyager was stuck on the other side of the galaxy and it was going to take them 70 years to get back to Earth.
Just to be clear the amount of energy required to create a 'wormhole' at the best minimum guess would be the energy of a whole sun if not more power than there is in the universe....forget it
Bending the fabrics of space-time and creating some form of a wormhole, this is a shortcut in my view. I believe that experiencing the long and harsh journey of travelling through space and time will allow us(has allowed us) to technologically mature. I think this idea of travelling faster than light is something that can not be possible for us beings anyway. I believe that as a civilasation, it is important that we think about our future in the cosmos. By doing so, we can ensure that future generations will benefit from our hard work, and fulfill our aspirations.
I think if we were to do something like that we would have to become a "hive" species like the Borg from Star Trek Next Gen where everyone just does what needs to be done for the group. Our world of money and capitalism and greed won't allow for it because it would be so EXPENSIVE to do. Whose taxes do you raise to pay to make a worm hole?
As a civilisation we can't feed ourselves and you want to explore the cosmos.
I think it's best to send white and asian women and black and brown men to cosmos to make a civilization. It will ensure a diverse population will emerge.
@@asoka7752 So all the whites get left on Earth with all the hot women and no black men. Deal.
@@asoka7752Hopefully if we ever reach a level of technology where we can do these things, petty social problems like racial politics will be long a thing of the past and we will just send the most qualified individuals regardless of what they look like.
What about the space ship needed to get there? Anything mechanical eventually breaks down and how will it be repaired?
Bring scientists and engineers, but you have to create an entire civilization at your destination for them to have the tools to work with.
What movie was the clip at the very beginning from?
"Passengers" (2016)
My theory is that certain types of space can be warped and traversed while other types of space can not . For example the so called dark space may be special in that the proper type of propulsion and protective force field can cheat.
Mother nature does this all the time in as much as she doesn't break the laws of physics but instead she makes new rules that go around what we thought was an impossibility.
My guy.....smfhhhh all of this is good, acknowledge the fact tho, simply because you enjoy and sexualize women often on earth, Doesn't give you the sense to say the universe is a woman. the fuck 😂😂
The key would be to encapsulate the craft in a warp bubble so no force is felt within the craft. Interstellar travel would require the ability to travel thousands of times greater than the speed of light.
Yes, a gravitational bubble.
In case anyone's curious, this is just clips of Tyson speaking at other events and on other programs dubbed over stock space-explory footage.
Thanks!
And thank you for your support :)

Why send a ship now if it will be overtaken in 50 years by a ship sent in 45 years
Correct.
If you and a friend stand on mountain tops, miles apart and could somehow yell loud enough to hear each other, it would take the sound certain anount of time to be heard from the other. But use a phone or Walkie, and now your voice breaks the sound of speed. Same will most likely be true for traveling faster than light in the future
Agree... we will send probes who transmit data back home at light speed. Our probes will be one way only.
And hopefully, still in the form of a walkie talkie
😂
I understand the science behind all of it but 50 years ago cell phones were not even invented yet and in the 70s when they were originally invented, they were more like barely useful bricks to deal with. My point is that just because something currently cannot be fully understood or solved, does not mean that it cannot be solved centuries or longer in the future. If we stick to the current science then it would be believed that traveling faster than the speed of light could turn into a form of time travel but all the things that are theoretical are not proven but just theories that seem most likely.
I believe the worm hole solution will be the only viable solution but none of us will be around to see any of that unfortunately. Even when it is achieved, governments and military will piss all over it and take it over for a long time before the rich billionaires or probably trillionaires at that time would be allowed to explore. It will probably never be available to common people though but at least common people might have the opportunity to take a ride far away and have their own little spaceship for more local travel after arriving where ever it is they're going to. The true exploration will always be restricted to military and the ultra rich so really, should any of us even give a shit about these types of advancements since it's unlikely to ever directly benefit common people expect maybe the chance to live on a different planet under the same restrictions here.
The fundamental issue I have with travelling at,or faster, than light is Einstein's energy-mass equivalence, as predicted by Relativity. The equivalence phenomenon is a proven scientific fact and fundamental fact of physics. A nuclear weapon ie. atomic and hydrogen bomb, works PRECISELY because the energy-mass equivalence IS a true and scientific fact.
You guys should check out the tv show Ascension
Starting with a bang! In the dawn of civilization, I'm pretty sure there was NO IDEA of "distant worlds", and also no idea of other galaxies until Hubbell discovered the universe (basically) in something like 1920. I think the idea of deliberate practical travel to other worlds is pretty much late 20th-century stuff!
Warp drives are basically you running in a straight line while someone is pulling a rug behind you 🤣
Bub….head for comic con!!! Tons of warp drives there!!!
I finally have heard someone say with our current understanding ... All science at any point in time is based on our current understanding of math and science. At this time we don't know what we don't know, and we don't know everything. One day in the distant future they will look back at our time and think how primitive our understanding of things were.
Matter cannot be accelerated to the speed of light.
What if you took a magnet that spun inside a rocker. On one end to convert the energy into a push forward. As the magnet spins it also gets faster and the output on the push forward becomes either close to the speed of light or it breaks the spead of light. You could probably eject it into a black hole or a large star as this is the only reason you could not use this method.
I think I heard of a similar idea but it is something that wouldn't work in space but on earth as far I'm not wrong .they should just star making a good nuclear powered space ship that can reach a realistic speed and start sending people to mars and back maybe under 9 months for each way that would be a good achievement too
To achieve the speed of light that way would take an infinite amount of energy. Nothing made of matter can attain the speed of light - period.
The planet we live on has been called 'spaceship earth', and since our destination is dependent on following generations, the idea of a generational ship doesn't seem so exotic, it seems close to home.
I couldn't imagine living on a spaceship travelling through outer space your entire life for a mission that you'll never see.
To do that we need to access the supernatural world to bend reality, Angel can do that and God...
Boldy going where 100s have been before! Classic
FTL travel has an inherent issue in that when you arrive, how do you slow down to orbit speed? This implies that you need mega energy to slow down, starting (when you are halfway there?) and also on arrival if coming in hot, assuming the occupants are human, or digital to survive the massive G's
Also true for slower than light travel.
Warp space and time little guy! Bend the universe! Ride the lighting! Laserships
Also, the generational ship should take inbreeding into consideration. You would have to have enough diversity of genetics to keep that from happening, since there would be many generations of descendants. They can't all be cousins.
Keen observation. No one has mentioned that yet.
So what, send a Royal Family used to it?
In order to have healthy genetic diversity for the crew/passengers you would need to also have thousands of embryos in cryopreservation.
The embryos (loaded before departure) would have to be screened to ensure their genetics are different than anyone else onboard the ship.
Beside maintaining a healthy genetic population for the ship, it would also provide (eventual) replacements in case of mass deaths (due to suicides, disease, or injuries/accidents). Thaw them out as needed. (It will take years before they can replace dead crew members but eventually it will happen.)
@@keeninsight1811 Good insight. Also, it will be many years before Humans are capable of interstellar travel. By then, new methods for preserving DNA, Embryos, and Sperm will have advanced. Maybe living humans can be placed in suspended animation long term with no harm to cells also.
@@UndisclosedViewer DNA is an amazing thing... we never really know who or what our offspring will look like or grow up to be.

I thought the Big Bang traveled faster than light.
"During the epoch of inflation, during the first split-second of the Universe's existence, when the expansion of the Universe occurred at a rate that was effectively far faster than the speed of light."
Also, negative matter travels faster than light.
Also, also... Quantum entanglement moves faster than light.
A) No, the Big Bang involved the expansion of space itself. Nothing was traveling through space at or faster than the speed of light.
B) What is "negative matter?"
What warp speed is quantum entanglement ?
What do you know about Hawkins radiation and braking causality when traveling faster than light?
You can't travel faster than light.
The "generational Star Ship" idea makes me laugh. Keeping a group of people on track for a specific mission for thousands of years is ludicrous. How much in common (technology, language, culture, beliefs, values, goals, politics, religions, ....) do we have today with folks on earth 23,000 years ago? Almost nothing. BTW - I picked 23,000 years for a reason. That's about when dogs were first domesticated. In a way you are scratching the surface as to why the Femi Paradox is no paradox at all. I expect the universe is full of life - all of which will be alone forever.
I'd give them two maybe three generations until someone goes off program and wrecks the ship. That's humans and that's what we do.
Well if you're stuck on a spaceship like that, you really have two options. Stick to the mission or die.
So yeah, they'd be screwed
That's why we will send unmanned probes with advanced AI. Probes don't require life support, sleep, or time off. Probes don't care if mission takes 100 years, or 10,000 years. When we went to Pluto we didn't send humans, we sent probes. It took over 40 years to get there. It was a 1 way trip.
I wrote nearly same comment on a different video on this topic. Not sure if you saw it or arrived at it independently. Either way I agree 100%
@@SoulDelSol Me too... great minds work alike. We will never send humans on long journeys. We probably will never send probes to our closest neighbors either.
Hurry up and make it happen, I've been tired of peopl... I mean Earth for 37 years now.
With the generational ship, would you not need fuel or some kind of resource? Or are you just free sailing through space?
You need fuel to reach your traveling speed, not to maintain it.
If you travelled at warp 10. Or 10 times the speed of light to alpha centauri would you not arrive 2.5 years before your own spaceship/starship was finished and deployed?
Warp 10 is not 10c. Rather, it is infinitely fast. Warp 2 is 10 times the speed of light. Warp 9 is 1516 times the speed of light.
Please cite your source.
Using a generational spaceship, the first crew would most likely be fertile women, no men, and a supply of frozen sperm because inbreeding is a real issue and having a crew at the destination that can walk and talk is desirable.
Probably not.
Space, I would suggest the crew would more likely be robotic rather than biological.
@@lukesball1 Please explain. I'm guessing you probably won't.
@@cps_Zen_Run That's not a manned flight or a generational spaceship. I don't see a generational ship as feasible due to us not being able to make a spaceship capable of functioning, maintaining life, etc for such a long period of time, 6K-50K years.

I love it., he explains something that is impossible as the energy to attain anything near the speed of light would be near infinite.
I've lost all respect for Neil deGrasse Tyson, can't watch anything he's in now..
Couldn’t agree with you more 👏
Why so?
Why
@@tccflash My guess is because he misrepresented atheists and failed at accurately self identifying as an atheist, which I agree with, I'm an atheist but I've gotten over Neil's misdeed... or it's Pluto.

What about time dilation and distance contraction in Special Relativity? Doesen't matter how many time has passed on earth. If we accelerate ship to reach 0.86 of C (from earth perspective), but it's time dilated 2 times relative to earth. 0.94 - 3 times, 0.98 - 4, 0.992 - 5. From ship perspective this 0.86c feels like 1.72c (because forward distance is contracted due to TD). 1.72c is 10g acceleration for a ~5.451 years
Say goodbye to your friends before you leave.
I am surprised they didn't mention the math behind hitting debri at high speeds. At .1 lightspeed, hitting a 1mm in diameter piece of rock or other debri would cause an explosion like a massive nuclear bomb.
Even a dust particle would.
So by the time I reach aplha centuries what will happen on earth..?? Hypothetical question
I think Neil hasn’t gotten warp drive by not thinking of the Alcubierre drive. properly. It’s not a wormhole. It’s contracting space in front and expanding the space behind by creating a warp bubble.
That's what I thought. I think he mixed up warp and transwarp. Well, at least according to how both are explained in Star Trek.
Warp drive/worm holes is the only way to do it, because even if we somehow created a spaceship that can travel at the speed of light, the time dilation would messed everything up.
yeah sure buddy, before you enter the wormhole is there a switch for you to decide what Galaxy and planet you would like to visit ? use your brain and stop with the ridiculous fantasies
You can't somehow created a spaceship that can travel at the speed of light.
@@brandonflorida1092 theoretically you can, if we can find dark matter and “somehow” convert them into fuel, but the time dilation is still a big problem like I stated in my original comment.
@@dejamike88 Nonsense. Please cite your source. Give me an Internet document which backs this up.

Onboard nuclear fusion reactors would be a great way to generate tonnes of energy for powering warp drives. How powerful would one need to be to create enough energy for warping space-time?
It is theorized that the energy needed for such a task would require matter-antimatter annihilation which yeilds pure 100% energy with no waste or byproduct. So this of course would require us to firstly be able to create antimatter in enough quantity to achieve this, and secondly, a method to contain it. I believe at our current state of technology, we have created a few atoms of antimatter, so we have a long way to go, but certainly not impossible though extremely challenging and improbable.
Using wormholes ignores a critical problem. You need a portal at each end. If we created a wormhole portal (somewhere near the Moon) where could we go? Nowhere. Because we don’t have a destination portal. You STILL have to travel to your destination sub-light and crest your portal.
The idea of generation ships ignores advancement in biotech that will - sooner than we have such spaceships - allow us to stop aging, rejuvenate and effectively keep the original crew living and working regardless of the trip length. 🤷
At seriously NAFAL speeds, yes...months shiptime = decades realtime
Try Ursula Le Guin's Hain stories
The commercials RUIN THESE VIDEOS. They interrupt at key points during the presentation. RUclips ruins learning and development.
Nothing wrong with being imaginative and hopeful, as a creature of habit no matter where we go, love and hate will follow us.
What happens to the speed of light if we add a second observer? 2 ships leave Earth going in opposite directions. From the perspective of Earth, both ships are traveling at 0.6c. From the perspective of one of those ships, the other ship is moving away from it at 1.2c.
Right. So what? Everyone is reaching his destination at .6c.
The concept of these generational ships is mind boggling. The mission of nearly everybody on board is to produce the next generation. It sounds crazy. But then again maybe that is how many people think today!
Instead of traveling fast through space…imagine traversing space by treating space as fabric …and going through ripples of the fabric …, imagine fabric on a table which bunches up in places …creating ripples or mountains and valleys ….and imagine traveling through those bunches of ripples like a needle would …instead of riding up and down the ripples of those bunches ..we just go through the bases of these ripples ..imagine how fast we could get from one end of the fabric to the other ..while traveling slowly !
Warp drive....sure. Except anti-matter isn't enough, fusion, none of that is going to be enough.
We won't even sniff 20% of lightspeed. And the thing is lightspeed is painfully slow in an interstellar sense to say nothing of the other issues of 'conventional' speed, like hitting things on the way to wherever.
Until we can work up the power of a star(a technical hurdle no one in the galaxy has done yet because we would have noticed that, we likely will never do it either), we aren't going anywhere as far as folding/warping space.
I have a feeling we get taken out by a gamma ray burst or space rock long before then, if we don't blow ourselves up first.
Warp Drive: Shows Stargate Ship. Wormhole: Shows Starfleet Ship. Well done, Cutting Guy.
Considering everything we see in the universe is looking back in time, how can we be sure anything light years away still exists?
depends on how far we're looking and what we're observing.
Theres also the possibility of finding a way of traveling close to the speed of light, due to time dilation and length contraption their voyage will be nearly instant regardless of how far they travel to, however many many years would've passed on earth...thats the catch, i guess.
My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." "V-ger's" message is sped up now that it's outside our suns time bubble or "Terran Time." It would be faster still if "V-ger" sent a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "Vyger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "Vyger" and the IP read time for as long as possible. They WILL show the flow of time speeds up the further away you from any celestial bodies. Until you reach the time standard.
•Our sun's time bubble: "Terran Time" we know and have measured.
•Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until Vyger is outside the Ort cloud .007-.07% faster, maybe. Just for reference.
•Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference.
•Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here so, surfing time here is choice. Though it's best to have your motor boat. ;-P
A minute is a minute in all. It's the rate/flow I'm talking about.
The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."
Pass it on, please and thank you.
Another way to enable faster-than-light travel may be via quantum entanglement; via this path we may be able to send information about 10.000 faster than light, as far as we know now.
Sending information is not 'travel' by itself, but who knows how far we'll take technology that can read and synthesize (biological) structures. If man-kind becomes capable to fully read a human body structure (including all memory), send the blueprint via quantum entanglement and reconstruct or 'clone' it somewhere else, that's a creative way to travel faster than light.
Safe to assume we'd have to get to the target destination first to set up shop though.
No, you cannot use quantum entanglement to send information.
We are essentially traveling around on a generational ship already. These ships would be additional.
Even warp drive , the speed of light has already reached the distance, the light already reached almost instantly, we are dragging to catch up ,
Look how far we've come since 1880 not only will we have warp speed will be beaming up and down with transporters by 2080, mark my words. Look at the flat screen TV's too much picture for the electronics but it works.
just like a water skier when boat doing 30 that makes a tight turn the skier is doing 50 mph , a long enough lever point in space with rockets instead of a boat can theoretically throw a craft faster than light .
We’ve been looking hard for things that are faster than light? I was not aware there was a scientific discipline dedicated to this. What is it called?
Actually, we haven't, since it's fundamentally impossible.
I also watched play school when I was growing up, the basics were fundamentally always the same, look at this shape and you will learn this, it was identified, labelled and when thought to be correct given a purpose even if big Ted was the one telling me so.
Created reflectively, as Mass always is in this universe, this seemed to make a lot of sense, however reflectively I then later thought about the fact that I was consciously reflecting on every bit of information that I was processing to form perception/s, which obviously led me to the restrictions of Mass and the question of why we would be taught that mass’s physical make ups are also the universal restrictions of the Universe and as time? Putting aside the laws of relativity, It was obvious that perception no matter how you looked at it, is controlled by your conscious ability to process frequencies as information, and since the Universe is made up of frequencies this would mean that your only detachment from everything else, is your perception that you believe you exist separately as a singularity. This being the case, means that everything else that could, would or can exist in the expanse of infinity, would certainly have an attachment to you through both light bound and unbound frequencies, but also realising that mostly YOU (not me) could only experience the unbound frequencies as mass if they are mimicked to you in other frequencies via a transport system I.e Cern etc- as you would know right?
Next I asked myself, because Mass is a restriction that is formed from cycled patterns of light, and the patterns for its identifiable shapes (labels) are essentially the same, Would they more accurately only reflect Mass’s believed limitations that are bound by Light because mass believes that they are the pinnacle? which as I stated earlier, it must, because of your forms of measurements. Knowing that frequency travels faster than light but also at the same time understanding that the basic perception of Mass can not comprehend this, I thought that it would be necessary to provide an explanation that was identifiable to Mass, so it being obvious that Mass is the grounding that bounds you to being a singular conscious reflection also provides the answer to zero mass (as per Universal patterns) that are not accidental, that without mass you are no longer bound to singular conscious reflection and become part of the grouped reflection of the results that you helped create or serve upon others as a singular or even as a group of singularities, I mean after all, as you keep telling us, all things Universal must be balanced accordingly as per known cycles of time and space yeah?
So lastly I ask, how and why would you or I possibly believe that the Universe is singular in perception? when you use measurement of another to form perspective of it? and if it is not singular then you can seriously still believe that mass can limit the Universe with it’s perceptions? especially when you know that things only span an existence when they are balanced correctly and the paths for these labels are multidimensional and eternal even if Mass thinks that it doesn’t travel that path, This being the case how could you even comprehend any idea other than the Universe is a multi dimensional super consciousness instantly formed from infinite timeless cycles supported by every and each relevant experience (from perspectives)that is ever produced through the freedom of choice by each and every singularity ever combined?
Mass is formed in time, time supports infinite experience
Freedom exists Freely
I don’t know…😉 I just thought I’d quickly write something
@TruthAIBalfour
A generation starship will never be an option except when it is extremely large and you could live a life just like that on Earth.
You can go back in time. And using warp drive and wormholes makes it possible.
You open a wormhole to a certain distance away from Earth and go through it. Then you warp drive back to Earth, and you would arrive in the past.
Please cite your source.
If a deal is done for Slot... it would probably be a summer move... so we'll need to get in an interim??... would have to be someone out of work at the mo?
If you're going faster than light how can we even detect something that we can no longer see with anything that detects things with waves?
The way to go is teleportation. It is done every day in the Canary Islands with protons
Pattent that and you can live the rest of your life off the licensing fees.
please do not forget one thing you need as much energy to slow down as you used to accelerate
True no matter what your speed.
