The prospect of interstellar travel is no longer sci-fi. It COULD be achievable within our lifetime! But, how would an interstellar rocket-ship work? On this week's episode of Space Time, Matt talks options for interstellar travel - from traditional rocket fuel to antimatter drives, could we travel to other star systems? Watch this episode of Space Time to find out!

I would be the one it happened to😂😂😂😂

so true
Agreed Sir Captain :)

It's a matter of size. If you think an interstellar spaceship will be the size of a bus, or maybe even an aircraft carrier, yeah, sand=problem. But an interstellar spaceship will likely need to be bigger than all boats, ships, bikes, trikes, cars and planes ever built, combined. And weigh multi-billions of tons.
Moving fast isn't particularly necessary: Making a ship that can support life indefinitely and trundle along, only pausing to gather supplies at other star-systems, is a much more feasible-with-what-we-know approach.

Don't believe everything he says. His calculations are wrong. 5:58 says we can reach alpha centauri in 3.3 years but it's impossible since light itself(fastest thing in the universe) can't get there THAT fast.
He said the journey would take 3.3 years in the astronauts perspective due to time dilation. So, it means that, in the perspective of those who stayed, the journey would take a longer time to reach its destination.
why not stop moving and let those planets come to us. because i think our sun and our solar systems is moving 800,000km/hr in our galaxy. if there is a space vessel that will stop moving relative to our solar systems, its like waiting for an elevator and the elevator is the planet we want to go to like the trappist planets.
This works in a solar system because of local gravitational effects, yes. However the theory breaks down when you start talking about interstellar travel. The reason for this is relative velocity. Yes, our solar system is moving at a high speed, but so is the target solar system. There's really no way to cancel our momentum and have that take us to another star. We have to just take our relative velocities into account, aiming for where the star will be when we are projected to arrive. Basically, it's like being an archer on horseback trying to shoot an arrow at another archer on horseback moving in a different direction.
Joaquin Michelini, I know you posted this 9 months ago, but to answer you: If we are traveling at near the speed of light, we would perceive the time to only take 3.3 years and we would only age by 3.3 years.
Amazing how many of these ideas were included in the Three Body Problem sci-fi book series.
Probably not by accident...

A spaceship miscalculated and hits a planet at 10% speed light with nukes on board, or a pile of unspent anti-matter...whoa, not a good way to introduce yourself.
More like strange matter and you transform their entire world into a strange world.
Of course theoretically, this is what would happen according to some physicists.

Good way to start an interstellar war. Better hope the species on the other world aren’t far more technologically advanced than us.

+The Brony Notion lol
3:40 "we need to use half of our fuel to slow down at the other end"
No, half your delta-v. Depending on what fraction of the initial mass is fuel, these could be enormously different quantities.
I was gonna say the same thing, "half the fuel to slow down" is totally wrong.
I think what he means is going from 0 to x back to 0 without anything but the fuel, which if he is, then he'd be theoretically correct (Assuming I'm doing my quick math correctly). Factoring in everything else would prove him wrong, but he probably didn't add those in either for simplification reason, or because he simply forgot to do so
Will Swenson Fuel has mass
Someone clearly plays KSP lol
He used the momentum p1 + v1 = p2 + v2 so the amount of energy to get to a certain speed would need the same (minus what weight in fuel you’ve already used) to slow down.
The ratios would be 2:3 or something
3:52 It would actually take 2*sqrt(2) times as long to reach Alpha Centuri because your average speed is much faster on the second half of the voyage than on the first half when you don't decelerate. Thus, it would take about 124 years instead of 90.
He also mentioned that you’d need half the fuel to slow down at the other end, that’s wrong as well because there is less mass to slow down (since you’ve already lost a lot of mass to accelerate).
did you forget that you had to accelerate at the beginning? or am i just missing your point
I was surprised that a big issue with traveling to the stars was not mentioned: friction and collisions. Even at .1C you're going to get an awful lot of erosion just from hydrogen atoms you encounter in interstellar space. At .8C that much worse. Just from the atoms you'd have to have a very strong shielding system of some sort to ensure your spacecraft doesn't simply get worn down to a nub and fall apart before you get a large part of the way to Alpha Centauri. And that doesn't take into account bigger things, like little pebbles or even microscopic bits of debris like molecules that could cause serious damage given their kinetic energy in relation to the spacecraft. Going at those kinds of speeds your inertia keeps you on track and it's difficult to see something far enough ahead to avoid the object if it's big, impossible if it's small. Electromagnetic shields could deal with smaller particles perhaps, and physical, ablative shields for the bigger, but that adds serious mass.
Correct - it's all impossible because even an object the size of a grain of sand would
explode against the ship like a tonne of dynamite at 0.1c.
We went to the moon and back in Reynolds wrap, not once but 6 times.
@@andrewarmstrong7310 so what - they weren't traveling at 0.1c
isn't there an inversely proportional relationship between mass and speed?
@@sorh Not in general terms. There is an inversely proportional relationship between mass and acceleration, assuming constant thrust (force), but you can get massive objects going very very fast on relatively small thrust if the thrust can be maintained for a long time.

"One design, our best chance. What do we build?"
That line gave me chills for some reason. I'm imagining some kind of game or series about the necessity of following that idea, having to FIND that one design and make sure that it actually gets recognized as such.
There could be some real twists and turns with new discoveries, shifting which option(s) you support and which you squash down, with multiple paths leading to different time scales for the ultimate escape. Maybe your support for your favorite option actually ends up disregarding the promising discoveries in favor of another option, that turns out to actually BE faster and you end up getting left behind in retributiuon for having actively worked AGAINST what turns out to be *our best chance* in the end.
This would be epic
Project Hail Mary
We don't have to intentionally travel to other stars. We could build self sustaining space habitats such as Stanford Torus's, O'Neill Cylinders and Bernal Spheres. With resources in the asteroid belt, the kuiper belt, the oort cloud and with comets and even rogue planets, we would spread our way to the distant stars in much the same way that ancient man migrated over the world just by building another village over the next hill. Multiple self sustaining habitats are also our best defense against extinction events. Such habitats could easily become a reality in mere decades and as with any real estate, could potentially net a return on investment.
Best comment I've read so far.
Except the distance between star systems is positively gigantic compared to the size of the solar system. There's nothing of use between here and there. It is light years and light years of total emptiness. It's like saying Europeans could have traveled to the New World just by building an outpost every few miles in the Atlantic so people could just swim across. Except there aren't even fish in space.
We still need to spread across the galaxy in order for our species to survive: all humans being in various habitats (planets, asteroids or artificial habitats) in the same small area of the galaxy makes us vulnerable to supernovae explosions. If one explodes in our proximity in the near future, we are toasted. Literally.
@@anthonydesportes9968 I didn't say that we didn't need to spread across interstellar space, just that we only need to be able to live in interstellar space to do so. Stone age man did not intentionally cross over to six of the seven continents, they simply built villages beyond the next hill. Just being able to build and maintain O'Neill cylinders, Bernal Spheres and the occasional Stanford Torus out of resources such as comets, asteroids and rogue planets in interstellar space would inadvertently take us to other star systems. Even a generation ship is essentially such a habitat. With our current technology, it is constructing such habitats that will take us to the stars and it would do so without us even trying once we are building such habitats.
@@EnDSchultz1 Yet already we have been mapping rogue planets, dwarf planets and brown dwarfs in nearby interstellar space. Interstellar space isn't as empty as you are imagining and without as many planetary gravity wells to interfere with navigation, accessing those resources should be quite straight forward as long as you can wait for the deliveries which self sustaining habitats should be able to do so. Remember that a single asteroid or comet would be enough resources for centuries to millennia for several such habitats. The fact that we recently had an interstellar object pass through our solar system recently shows that interstellar space is not without resources.
You miss a bigger issue - Shielding. If your going at the speed of light and you hit a speck of dust, you are dust.
Radar, hello?
@@hannahmadden3573 And how do you propose to dodge it, not even talking about spotting it.
Hollowed out asteroid with some engines slapped on it's ass, takes care of shielding from objects and radiation. Stick a whole bunch of cameras all over the surface and have display screens on the inside instead of windows so you an still see cool shit as you fly by, obvious radars and detection equipment with hi powered lasers to intercept the larger objects that may do more damage. All the little stuff like micro dust will just slam right into us, leaving us cool craters to check out with our surface cameras,
Good point.
You could make an ablative shield out of ice. Hopefully you could find some on the other side to replenish it.
how do we avoid hitting meteors and other space stuff at such a high speed?
+Eshan Das Shielding is a huge issue, you're right. The faster you go, even the smallest of objects can cause great damage on impact. Imagine trying to get out of the Oort Cloud traveling that fast! The good thing, though, is by increasing your speed you actually limit an object's ability to collide with you based solely on that object's own trajectory -- you'd have to run into it head-on basically.
+Joseph Proffer not sure that i follow you on that, but in my head im thinking of when i try to throw my mashed potatoes into the ceiling fan-- i rarely ever hit the fan and my potatoes just sail through to the ceiling above...
theonlyari Yes, exactly! You'd have to hit the blade dead on, the speed limits the ability of the fan blade to impact your potatoes. You could think of this in an opposite manner: if your potatoes were travelling very slowly, the blade suddenly has an even greater chance of coming into contact with them. The problem with the Oort Cloud, however and sadly, is that there are a loooot of fan blades. haha
+Eshan Das well, we sometimes avoid them on Earth, but we have an atmosphere that causes friction which leads to most objects disintegrating. With a mini black hole, I wonder what sort of gravitational forces could be expected and if that would be enough to retain an atmosphere, though we'd also have to consider solar winds. The black hole would also generate a magnetic field. Ultimately, I think we're going to need an artificial mini planet with a black hole at its core.
Also the probability of hitting an object is actually really small and decreases quite rapidly outside the solar system. The Star Wars asteroid fields don't really exist. Entropy is such that things tend to spread out evenly.
+Eshan Das we don't. there is not much out there n space, debris is collected by larger objects. the interstellar space is just that: space. it would be actually pretty surprising to hit something. other than that: by travelling so faast,you push a blast wave of particles in front of you, they could act as a shield by vaporising stuff in front of you.
The fact that most of this is possible just makes me happy lol
Sadly, but the time it surface in reality, we're already dead.
@Universe3141 I mean the time this idea of this possibility realized. It takes a a ton of time to make interstellar travel to become real.
@ if we can mobilize the entire earth, ignoring the fact that more than %99 of total population would die and at least billion would fight themselves in other to get to the ships, which will slow down the progress even more
None of this stuff is ever going to happen, despite all the starry-eyed optimistic dreamers.

Great video!
My only doubt was... How do you even harvest a Black hole? How are you saving the radiation and make it propulsion?
+Luis Alejandro Carrasco Molina Actually, the kugelblitz is an artificial black hole. You make it by concentrating an extremely high intensity of light in a very small region of space. If you can also give the new black hole electric charge (feed it some electrons) then you can suspend it in a magnetic field. The charged radiation it produces can be channeled by magnetic fields as propellant or the heat can be used to power a conventional generator. However you're right to think that it's a big challenge to harness very high energies. We don't have the materials to capture the highest energy non-charged products of proton-anti-proton annihilation, for example, and I imagine the same may be true for this Hawking radiation.
+PBS Space Time I was wondering how can we hold a black hole in place when you mentioned it in the video. Good thing that you explained it here. Although it'd be good to mention in a video. In the next video's comment section, perhaps?
+PBS Space Time wouldn't the biggest problems with the kugelblitz be generating the massive amounts of energy needed and then focusing that energy into lasers. You would need lasers pumping 53 octillion joules into a single point nearly instantaneously. That's more energy that our sun produces per second.
+PBS Space Time But... it's a black hole.. am I the only one terrified of it, you know... eating the ship for breakfast? Is it because it's so small that it could be contained?
UnknownXV Black holes don't suck anything in. They have gravity yes but that gravity is only as strong as the mass equivalent contained within the black hole and it's only once you get near the event horizon that things will get screwy. the 600 billion kg of mass mentioned wouldn't even be noticeable gravity wise.
The problem with lasers is divergence. Early on you might have a nicely collimated beam, but there is no laser with 0 mRad of divergence. The farther away you get from the source, the lower the energy density of the beam gets.
12:25 - This one aged well
The real question is how big will the explosion be when our spacecraft traveling at 0.1c or faster hits a grain of space dust.
Big. The relativistic kinetic energy of a grain of space dust weighing 1 gram traveling at 0.1c is 452 gigajoules - equivalent to 113 tons of TNT. I don't know if one gram is a good approximate weight for space dust but if it is then hopefully the dust is really diffuse.
That means
L1. we need a lot more of energy to support an "energy shield" Though, impacts slow the ship down.
L2.....so long as we have a fusion reactor....E=MC2 the hell out of that mater and use it to further propel us. Fusion Bombs?.
L3. Use excess energy to clear debris in the path (ha. Space ship turns on its headlights) and direct the debris to be collected.
+@@jimstone2235 - We use deflector dishes for clearing the path.
Funny you should mention an Earth-like planet at Alpha Centauri hearing recent news.
Was about to say
It is located in Proxima Centauri :)
+gabichri but it's still in the Alpha Centauri system.
oh and gravitational waves too :)
Earth has many characteristics. "Earth-like" is actually pretty vague.
"So we don't see any ducks, but something's quacking and eating all our bread sticks." Classic, and pretty cool that we now HAVE seen gravitational waves since this video. Onward, science!
Yes😂😂
A modular starship would have a great deal more versatility, be further expansible, and would alter velocity/vector with less duress, maybe even allowing for gravity to assist in such transitions.

The reason you can't go through a wormhole is because the point of connection between spacetime is frozen in time, so even though both spaces are connected, you can't get past the point where you don't get to have the next moment.

The one who discovered the lost toilet paper vault, some say there's a thousand years worth of toilet paper in the vault that was meant for the people who survived the apocalypse to build anew.
Unfortunately it was Kirkman who found it first and at that moment he became the most powerful being alive. With his newfound power he crowned himself the first King in the end times. King Kirtman forged himself an empire that was unmatched with a legion of soldiers that would not go unwiped. Although it does not seem all hope is lost, the one known as Charmin of Clan Ultra seeks to unite the people and defeat Kirkman so that our children's children will never go unwiped.
It makes a lot of sense to ignore the Wait equation and just launch as soon as we have something feasible.
It provides a benchmark, we enjoy learnings, geopolitical situations may change, and being able to create faster craft is partially just theory.
Plus, you have to find astronauts who are willing and psychologically totally accepting of the risks of dying enroute, so the "I'll wait to go later with better tech" wouldn't be a factor.

imagine thinking "the wormhole from interstellar" is a viable real world idea for sending a spacecraft somewhere right now
Murph! Murph! Murph!!!!!
MAKE HIM STAY MURPH!!!!
It would be a lot more efficient to send frozen human embryos, to be incubated after the ship reaches its destination. Assuming that it's possible to make artificial wombs, and that robots could build a habitat and take care of the kids until they grew up, you could make the spaceship super small and light weight. That way, it wouldn't bankrupt the human race to try and accelerate a battleship to 0.1 C, instead, you could accelerate a ship the size of a bass boat. Speed it up with rockets and a light sail, and slow it down with an ion drive, and you might have a human colony on an alien world in 20,000 years.
' Well enough' is a low bar considering the way a lot of kids get neglected and abused by human parents, but still make it into adulthood. AI could possibly be up to the challenge of providing basic necessities, and education to the first generation. I assume, that, after arrival, the mission could use raw materials and energy of the new solar system. Perhaps the spacecraft could spend a few centuries mining asteroids and building a lander to send down to the surface of a habitable planet.
This might have been the way human life started on earth in the first place. Mind blown!

It'd be incredibly lonely.. especially for writers, who just wanted to write their own novels; for creators, who just wanted an audience to see thier quality art or content, and researchers, who just wanted to continue their papers and be acknowledged. It'd take 4.5 years to transmit a message with all that to Earth and double that to get a message back and it might even get lost. It's just sad thinking about being in another planet that far. Well.. at least for me. I cannot help but feel like there's a lot of stuff I'd like to give Earth before I go.
As for the other part of the population who are totally fine with leaving Earth, I'm pretty sure they'd have a lot of matrix-like simulations powered by AGI virtual characters, and infinite worlds to explore on the generation spaceship, and also on the foreign planet. They'd probably live the happiest live like that I guess.
Maybe if the spaceship was large enough, it might not feel that bad. Like at least thousands of people with different opinions about different stuff should be present to create an environment. If everyone liked the same stuff, mind biodiversity is pretty much killed.
The spaceship should be also kinda like Noah's with many different animals at sections of it for farming or even petting.

I think that another thing to consider is the affect of acceleration on the human body. Some of these options would see us accelerating at a rate that is to strenuous for our bodies to handle for long periods of time. The time that it would take for humans to safely accelerate to 10% the speed of light should also be factored in. Great video as always!
We do not need to safely accelerate, we just need to get rip enough to survive sudden acceleration of 100G, without seating
"The Expanse" solves this very cleverly, by accelerating and decelerating at 1g in most routine travel, with ships space layouts that are reversible, thereby providing articifial gravity for the crew along the axis of acceleration. Higher accelerations require them to be strapped in and on drugs!
I like the solution in the Forbidden Planet, where they are turned into solid objects for the deceleration.
Why none of this will most likely ever happen, just one of the examples:
US Military spendings (2015) - 600 billion USD
US Science spendings including NASA budget (2015) - 30 billion USD
Similar is true for EU, Russia, China, India, Japan, etc.
The point being, people who rule the world couldn't give less fucks about space, most of them are too unintelligent and uneducated to think about the future, and too busy finding ways to blow someone else up in order to take a little bit more useless land that they don't need because they've got more than they can handle at the moment anyway.
Let's face it, the world has only seen rapid evolution of space travel one, during the Cold War, and we all know that the point of that evolution was NOT science or new discovery, it was pure politics and flexing muscles.
If the world was ran by scientists, engineers, doctor, etc. we'd be colonizing other planets and star systems already, but sadly, the world was always ran and most likely always will be ran by old farts who live in the past and don't have the intellectual capacity required to push the world forward.
i think the usa will spend more money on nasa if they could get a possible way for this stuff but yea still the military spendings are retarded
That's because of private contracting. Vary few in the private sector make a profit from NASA, and thus vary little lobbying is done for a increased budget. Military spending on the other hand is almost almost everything is contracted out to the private sector. Thus you have more alot more lobbying for increased military budget.
beaconrider It depends on the level of technology said colony starts with. if the colony had access to something along the lines of a Universal constructor (Molecular Assembler) and adequate power source. At which point resupplies become unnecessary.
War is an excelent motivation for advancement if no conflict existet there wouldnt be as much drive to push forward.
In a completely peacefull world progress would actualy slow down.

Powered by a black hole? I've seen the movie event horizon, no thanks. 😅
OMG I was thinking the same thing. However, in Event Horizon, the black hole tech was used to power an artificial wormhole and not propulsion.

Dimensional travel would be interesting.

It would be amazing if our attempt to reach another planet so that we don't go extinct, is the cause of our extinction due to war with an advanced species because they consider it an attack. Except it wouldn't be a war, they would simply annihilate us the way we do a hive of insects.

While talking about thrust is sexy, it generally overlooks the bigger and more ho-hum problems involved in building a machine that will have to be powered and operational for 100 years. Think about how often large complex machines need to be put up in docks for refits, even crowning achievements like aircraft carriers or nuclear submarines. These conversations usually leave out MSEs or other disciplines that deal with these problems, but there are some potentially insurmountable issues here.
+neeneko guess we will need to develop self-healing materials and repair nanorobots first.
For me it goes without saying that without sufficiently developed on-sight fabrication technology and general nanotech stars are closed to us. We simply won't be able to bring enough nowdays machinery with us to mine resources in the destination star system and fabricate needed components.
+Atila Elari Another big area of worry is one way chemical processes involved in some materials, or at minimal process that get more expensive each time. Sealants are a huge issue. The humble rubber washer for instance decays over time yet is critical for keeping gasses and liquids where you want them.
In my opinion, the fact that once the machine is accelerated it is technically just floating thought the vacuum of space, will limit the concern with this wear and tear. But I agree that lastability is an important factor to consider, as a materials engineer at northwestern, I do know that there are metals and polymers that can self heal, either through chemical, reactions or by introducing an electric current.and we have that now. Imagine what we will have in 50 years.
+neeneko Yes thrust is sexy.
+neeneko absolutely, most physicists dont really have much hope for interstellar travel in our lifetime. Who knows how things will be in 100 or 500 years. But for now? Even if it sounds possible, it doesn't mean it's feasible. Star Ships that last generations are at the moment the most realistic option, but the chances for success are very low. Space is a very unforgiving medium. One mistake, and it's over. You can increase the chances by sending maybe 10 or 100 ships on their way. But still. It would be extremely dangerous. The cost in material and human life might be very huge.

Since the starship would have to be quite large and be built in space. We would be better off capturing an asteroid and insert into earth orbit. Then they could hollow it out. The asteroid would carry much of the materials they would need to build it using robots and 3d printers. Ideally, build it in a way so they could replace the engines on the go. Then if they are able to design a better propulsion system they would be able to integrate it into the ship. With scientists and engineers having just under 50 years, they would definitely have enough time to advance technology.

0.1 speed of light achieved in 20 days turns out to be 1.77 G's. Rather uncomfortable for 20 days. If you reduce to 1 G the time goes to ~35 days. (a = (v2 - v1)/t) Seems like a better way to go.

I can't get enough of this videos. Keep 'em coming!!
The biggest problem with Orion which he alludes to here, is that 300,000 bombs would be required. In over half a century of the cold war, two superpowers were only able to crank out 100,000 nuclear bombs and that's being very generous. The cost was probably in the low trillions just for bombs. He later accurately touched upon this problem. Fusion seems the most realistic to me. Although we'd need to raise it's potential to probably 50% SOL minimum for interstellar trips to be practical at all. I'm not too enthused about anti-matter due to it's cost. Pion drives capable of accelerating to .1c in 20 days would be too much accelerative G load for humans. The best I was able to calculate as far as acceleration and "G" loads of around 1.1, was 270 days just to reach 80% SOL. I suspect interstellar travel is 500 to a thousand years off just for our first human mission. I also think we will have to discover some new type of a more practical propulsion system not even imagined today. But my timeline comes from the problem posed by "The cost barrier". As a government project, interstellar travel has no chance with tax funded government projects functioning as they do today. Keeping focus on the project would be enormously difficult considering the government or more accurately, taxpayers failed to sustain post Apollo spaceflight and we wound up with the economically failed shuttle. An emergency would help tighten focus, but I don't see any short term emergency solution as being possible for a variety of reasons I won't go into here.

This would be useless with a limited amount of ships because the people who can't go would riot until no one can go.

“It’s Rocket Science and Nuclear Physics...so..it’s hard.” I love it lol
I'm a bit confused on how going at 10% C would work in real life. Let's say I was going that fast, wouldn't that mean when the rocket smashes into tiny debris on the way (and it will) they would hit the rocket with the energy of their mass times 10% C squared? Wouldn't that completely destroy any space ship?
That energy isn't 'mass times 10% c squared' because the collision isn't fast enough to be relativistic, but it's still pretty high.
You'd need some sort of shielding. Project Daedalus proposed doing it like this
en.wikipedia.org/wiki/Project_Daedalus#Concept
"
The ship's payload bay containing its sub-probes, telescopes, and other equipment would be protected from the interstellar medium during transit by a beryllium disk, up to 7 mm thick, weighing up to 50 tonnes. This erosion shield would be made from beryllium due to its lightness and high latent heat of vaporisation. Larger obstacles that might be encountered while passing through the target system would be dispersed by an artificially generated cloud of particles, ejected by support vehicles called dust bugs about 200 km ahead of the vehicle. The spacecraft would carry a number of robot wardens capable of autonomously repairing damage or malfunctions.
"
send more than one probe
Bad End Happy yes, the starship would need some kind of magnetic shielding or spacedust collisions would be catastrophic. Hopefully we can come up a gravity/antigravity drive to bend space and not have to deal with stuff like that.

Imagine reaching alpha centauri after all that time and money just to discover the candidate planet is completely uninhabitable. Seems pretty unlikely the closest star system would have conditions conducive to life from another star system.
Slowing down or changing course is a good question to ask. It would suck to slam into an asteroid field or a rouge planet at 10 percent the speed of light.
Forget asteroids, slamming into a speck of dust would be fatal at that speed.
luckily space is like 99.9% empty
Preface that’s cool I didn’t know that. Even at a .1 percent chance I would still be wary though. I have never had good luck with odds. 😂
Dude if we hit even one micrometeorite at that speed it will obliterate the spaceship let alone a fist sized piece of space debris.
You will have to develop force fields way before you can think about accelerating.
Now if you develop force fields you might want to develop one that makes the spaceship have no mass.
Once the spaceship has no mass it's very easy to go almost the speed of light and to do it with very little fuel and not have to worry about hitting a bug on the proverbial windshield of the spaceship which would split atoms and actually behave quite like a mini nuke.
Shielding has to come 1st
Zero point energy.
You can't just make mass not have any mass. The reason it's so hard to go light speed is that anything with mass needs energy to accelerate. Also, there aren't any bugs in space. We don't have the technology to create a force field, especially one that would protect a spacecraft that's going lightspeed. Do some research before trying to teach people things.
Spock knows
Sorry teacher
@@cashhawker1735 Sounds like you completely missed his point. His point was not the force field but the indisputable fact that hitting anything at those speeds would cause massive destruction. Force fields do seem far fetched but the issue has to be addressed somehow (don't know if there are any ideas out there).
I wouldn’t mind having a light sail and just cruzin through space
The moment he said "There is some very serious rocket science in this episode about farts" I died laughing. xD
