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!

Imagine being sent to alpha Centauri on a fusion ship you spent 90 years on only to arrive and find humans there because about 20 years after you left someone figured out how to use a black hole drive
I would be the one it happened to😂😂😂😂
@@shelliejones434 F
but imagine that the humans who used a black hole drive arrived to find that humans have been living on Alpha Centauri for years after arriving via Quantum Teleportation! Dang, hate when that happens!
I mean I’d be happy to see company tho, lol

I don't know if I've ever gotten this man's name, but I've watched a lot PBS Space Time and I really like the more laid-back style he has in this video: he's more animated, he's making jokes, and he has a little grin like he's just in his zone and loving it. I guess what I'm saying is that I find his enthusiasm in this video more engaging than his more rigid presentation in other videos.
Apparently he gets more excited and animated when presenting sci-fi fairy tales like this video.

@@NondescriptMammal optimistic? sure. impossible fairy tales? maybe not so
@@icinnalatte Maybe not. But the furthest that a human has ever traveled from earth is the moon, and we haven't even done that for fifty years. Suddenly we are going to solve all the logistical problems for safely transporting a live human 100 million times as far as that to the nearest star?
*“Born too late to explore the world, and too early to explore the universe”*
Kyle Lin Not necessarily. We still have about 95% of the ocean undiscovered. Sure, it’s not as interesting as space, but it’s still something!

We can't find even find Planet X in our Solar System...So yeah
@@Fly--Crippin--blu--boi187 well no one has been further than the moon so any other planet in the solar system hasn't been explored by humans

That awkward moment when you actually have the tech to reach 10% the speed of light in a ship... then collide with a particle of matter the size of a grain of sand and watch your ship get destroyed 😂😭
so true
Agreed Sir Captain :)
Have a bumper on the front just above your license plate
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.
tru tru tru. But just imagine shields. LIKE SHIELDS ON OUR SPACE SHIPS DANGGG
Amazing how many of these ideas were included in the Three Body Problem sci-fi book series.
Probably not by accident...
and many other SF books over the decades 🙂 Alcubierre warp drive is a description in general relativity of a warp drive from Star Trek. 🙂
The fact that it would take us 120,000 years to get to the closest star is mind boggling and puts into perspectivie how ridiculously small we are
Did you watch the video? We could get a man on the nearest star in 150 years and a robot there in 50.

“Pretty realistic”
“Increase our antimatter output by 100 trillion trillion”
Think about how much faster how internet speed has gotten over the past 50 years. It used to be 2.4 kbps and now it's 6000 mbps (publicly available). That's 6.000.000 kbps. Or in other words 250.000 times faster than it used to be.
We simply need new innovations.
@@warbreakr 250 000 times and 100 trillion trillion is kinda different

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.
@Trevin De Alwis 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.
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
It's a little bit depressing knowing that in my lifetime, we might send a probe to another star but it will take so long to get there, and for any information to be sent back, that I almost certainly (without a major breakthrough in the cure for aging) will not see the results.
+Lutranereis good thing there's many breakthroughs for "cure for aging" in store, at worst 20 years from now. ^^

Bill Whitis That was actually prophetic.
"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

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.

12:25 - This one aged well
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.
I was expecting something like " a fuel tank as big as the Earth" but as big as the observable universe?!!
I'm just sittin here like :O right now :D
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.
I've got a question. How did You manage to make Space Time my favourite You Tube show?

Could you supplement a kugelblitz's mass with matter and use that to create a hybrid kugel/matter black hole?
Also could you, instead of or in tandem with lasers(assuming we get to that point) use a particle accelerator to supplement the energy required? Or would the apparatus be so big that you'd be better off using one or the other?
Amazing video! I found this very informative and interesting.
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.
That’s what happened to the dinosaurs fam
Good way to start an interstellar war. Better hope the species on the other world aren’t far more technologically advanced than us.
Sam kela maybe that was our civilization that hit the Earth presumably in a “meteor” but maybe it wasnt a meteor but rather some technology like in the video from another solar system. 🤔

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.
In your opinion…
@@Rob-cy8xc You get how time dilation works right? When you reach the event horizon of the wormhole, how do you get to the next moment?
humor and shirts greatly improving your personality shining through is AWESOME!
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
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.
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.
Let's figure out FTL communication first lol. Say through an artificial wormhole or something; at least to keep us connected to our people out there.
The “Pion age” is going to be a interesting time to say the least.
And yes. We should totally strap the riches to nuclear propelled rockets. We have plenty that shouldn’t be used for anything else.

I don't think any old lawnmower engines will get us very far.
I've seen, I think it was Kurzgesagt's treatment of this topic. But I had no idea this channel existed til recently, and I'm excited to see their take on it!
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.

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,

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.
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.

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.
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.
... as usual, massive thanx and kudos, please ride onn ... will try to remember to include the future space-babies in my medits ...
I am amazed at how people still think that wormholes can be used for interstellar travel. According to real experts wormholes are still only theoretical, and can manifest only at the quantum level, and not in our macroscopic reality.
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.
Not that retarded when you realize that the US has a GDP approaching 20 trillion USD
Hello I'm from the distant year of 2019. Gravitational waves are observed all the time now! Boo ya

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.

“What do we need to build a starship”
Elon Musk: hold my rocket
Hate that guy. Stupid poser
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.

@Metalcore Reactions I was wondering if anyone else was trippin on this guy!
😂😂😂😂
When you are in space; can you harvest static electricity and turn that into power for deep space exploration? Since light will be harder to collect at a far. Also has anyone looked into using magnetic fields from our sun and planets as a means of travel; meaning creating a space shuttle that can be negatively charged to get pushed by the suns mostly positive field? you can build a giant solar magnetic "net" that you can extend for travel purpose then collapse in means of slowing down or for maneuvering. dont be afraid to message me, ive been thinking about means of travel through space for awhile
yeah i've thought about something like that and looked it up before, the problem is that the magnetic poles are far too weak to cause any reliable acceleration
Static electricity is not equivalent to normal electricity.
Since there's no closed circuit, the charge will accumulate on the craft until it reaches equilibrium with the ambient charge.

I read some books back in the fifties written by a guy ( George Adamski) who claimed to have been in one of these flying saucers and he described the means of propulsion as being magnetic in nature, using the natural charge of bodies at the poles. Is this even something worth looking into?
It’s insane that we could absolutely send humans to another star RIGHT NOW, without warp drive, without cryogenics, without any exotic wormholes. Whether or not we’ll find an accommodating habitat on the other side is another question. But assuming we send, say, 100 of these nuclear pulse colony ships to the closest 100 stars, odds are at least one will have a habitable planet, yeah?
No.

Anti-matter drive is a very exciting possibility! We just need to figure out how to mass produce anti-matter. The potential it has as an energy source is amazing. 0.8c! Can you even believe it? But with anti-matter still being so hard to create, it might take some time, and until then, fusion should work ok.
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!

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. Like the movie explains, they fold a piece of paper and punch a pencil through. It was the space between the paper that ended up being Hell or something like it. Dimensional travel would be interesting.
You just made the hair on arms and legs stand up by mentioning that movie. I saw it at the movies as a kid during a storm and the movie theater power & movie started flashing on and off . Nothing to do with that weird experience & have seen it a few times in my adult life & just something about it that creeps me out like crazy & I’m actually a huge horror fan & movie buff & not many movies that bother me or can’t or won’t watch, but something about it that makes it the most terrifying thing I’ve ever seen.

@@theharpspedeffect9209 I still have the dvd, and I've only watched it once. There was something about it I didn't like, and I think it's creepy too.
Thanks for conceding the "Romulan connection" of the blackhole drive: it was the first thing I thought of (referencing the sixth-season ST:TNG episode, "Timescape," for all you non-Trekkies). But once again, a lot of these real-life proposals seem to have fictional analogues (is that a word?), and this is just one example.
Overall, it's looking like interstellar expansion will be a complex mix of manned and unmanned exploration, typically involving sending a LOT of probes & machines ahead of us, or sometimes, even instead of us.
This is really making me wonder. The schwarzschild kugelblitsz is really interesting because with lasers that powerful we would be able to use the lasers to test Mallets time machine to send messages to the past as far back as was when they're first turned on. So we might theoretically receive the results of any journey from our future selves before we even send the ship. Would we be able to record the messages/information and then give the ship a new target destination or would some kind of quantum eraser effect delete the "waveform" of possible information when we observe it? If we could save the information it would be like a crystal ball that allowed us to literally choose our future by selecting it from possible ones. Even better lets assume by then we have matrix like VR, we could have the information from the future represented there to actually experience it and would essentially have explored everything that was possible for us to explore without actually having to go do it. It would be like a temporal internet where all possible timelines of humanity were contributing to a "waveform" of possible information while at the same time never actually contributing. If observing collapses the waveform then maybe you would have to ask a question and some crazy AI that wouldn't be able to actually read the information giving you the answer until ironically we first know the question we need ask in order to preserve the the waveform. The implications to freewill and reality if any of this was possible is really messed up, never mind the fact that if it worked we probably wouldn't be building a ship to physically explore the universe but a computer powerful enough to be able to handle all the possible information. I'm sure there's holes in my thinking but hear me out, what if the solution to the fermi paradox is once we reach the threshold of this laser and information technology we no longer have a need to explore to survive because we could create closed time curvatures containing everything we need and would have no reason to leave the universe we create for ourselves because we would be able to experience what ever we wanted in it.

Can you do this kind of video again? Maybe a 2021 update of interstellar travel impossibility and how it is
Compared to your modern Videos, this feels like an Action movie with all the Hand waving :D
I've watched a few of these videos about interstellar travel and they never mention deflector shielding. Hitting a small particle at that speed can be devastating.
That is one of the big problems. At relativistic speeds, hitting a grain of dust is like getting hit with a modern tank gun.
Another problem is blue shift.
there are ways to achieve interstellar travel that circumvent this issue and make it irrelevant, though this video does not explore them
That one guy with the speech impediment, his videos explain it very well. Can't remember his damn name tho....

Nor do they mention payload and how on earth you would address the fundamental of human biological requirements on an extended space journey. And, perhaps most importantly - the scenario described presupposes that the entirety of mankind would somehow lock arms, sing Kumbayah and support such an effort. This is without a doubt the most unrealistic supposition of all. Why on earth would the entire global community commit its entire set of resources on such a low-percentage of success project which would benefit only an infinitesimally small fraction of humanity? How on earth would you ever get agreement on which individuals would be the ones to send?
the funniest thing about the gravitational waves question is that the first gravitational waves were observed exactly one day before this video came out but where only announced on february 11th. 2016

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.
2:09 i just discovered this, would love one done today. 😊 loving learning with you ❤
Currently the Juno spacecraft can travel at 165,000 per hour which means it would cover a light year distance in 20,000 years. Now to reach light speed of 186,000 miles per second would be a significant jump but even at the speed of light, space distance would take countless human lifetimes to travel from most points. For instance to travel to the center of our Milky Way Galaxy which is 26,000 light years away at light speed would take thousands of human generations. At best humans may be able to putter around our solar system mining planets and comets.
Space travel should be done right...and in style. I don't want to be poking along on a 90 year mission to Earth 2.0 and get passed by some kid going 0.8c at year 80.
Use the nukes to move that asteroid, then make more anti-matter!

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.
