"Do you want to be nomads again?"- Question thrilled me..

[@olegzandrvondenmanoresoftw596]

yes, and a couple of new empires

[@elck3]

It didn’t thrill me but it did pique interest. IMO going from land to sea was much easier (to be a nomad) then it was going from earth to space. Two vastly different means. So it’s a bit facetious and rhetorical to ask that question. Yes some of us would like to be nomads but that’s easier said than done

I'd like to see your plans on dealing with dust particles moving at a good fraction of light speed relative to the ship.

[@Spscc23998]

Good point. Even at just half light-speed, impact with a one-microgramme dust particle is going to yield more than 11GJ of energy. Some form of multilayered shield, possibly?

[@tomctutor]

Simple your spaceship' mass has increased (relativistic mass) compared to dust particle - so it would obliterate said particle (Voyagers still there 40 years later)!

[@tylerdruskoff9689]

While there still is dust particles you have to remember that is IS space and interstellar space is WAY more empty than the emptiness that we call space around earth is. But still, there are some(in the most generous sense of the word).

[@bejoysen4468]

@@tomctutor, 1) from your rest perspective, the dust particle is the one with all the momentum, so it would obliterate you. 2) Voyager isn't traveling anywhere near relativistic speeds.

[@magnanimus1150]

If you guys saw that tv show the boys in the opening episode you have the runner just PLOW through that woman on the side walk. It's a similar comparison. If you try to put 1 human through another human its bloody difficult. But add speed and you now have kinetic energy making you much more packed with mass and evenly focused and moving in one direction and boom he plowed right through her. Same thing with a ship. As long as you have a good heads up display to avoid bigger things like planets and comets I think you would plow through smaller objects in space due to your mass and speed. Kinetic energy is where its at. Throw a bullet through someone by hand. It's not going to do much. Now fire it from a gun and that lead piece will you right thru you.

[@petyrkowalski9887]

I would love to see a follow-on video about how you would navigate through space as you go faster and faster to avoid hitting solid matter which would destroy you. 1g constant acceleration doesnt sound much if you have a constant energy source but navigation safely would be tricky to say the least.

[@filmcale]

Hello. Great video! Would love to help clarify for viewers: At 85% the speed of light, using antimatter propulsion, someone would arrive in 2.7 years, not 5. To us, of course, nothing can go faster than the speed of light.. which is a crazy thing considering that Alpha Centauri system is approximately 4.367 light years away. However, we have to consider relativity. On Earth, 'I see' (with my own eyes) that it takes 'you' 5 years to travel to Alpha Centauri. On the other hand, if 'you' are the one traveling to Alpha Centauri, only 2.7 years pass between the time you left Earth and arrived on Alpha Centauri. Gotta love time dilation.

[@AndyChungsCarromPool]

However, it makes me wonder and it makes me anxious just by thinking that a person who took off to Alpha Centauri would just feel as if 2.7 yrs have passed while it would be 5 years for us. The gap widens again with our target being distant. So does it mean that the person on the spaceship is a futurist who can actually go forward in time? I am not an astrophysicist just a novice but always curious and silly!

[@robertmuldrow591]

One thing he never addressed and solved was the amount of matter that exists even at interstellar space, all of which you will be slamming into. And the faster you go, the more devastating they become.

[@EliasAlucard]

Yeah, that alone makes this entire TED speech a complete fraud. Faster than light travel is only possible through wormholes.

[@PhillLOL]

I've wondered about the same thing. You are bound to hit some asteroids here and there. It's not just "smooth sailing".

[@Boog_masskway]

Yup there would be a ton of problems that we would need to solve before this becomes remotely possible. Slamming into stuff, decelerating, maintaining human health and wellness, hibernation, protocols for encountering other intelligent life etc

[@hqcart1]

ever heard of auto pilot?????

[@PresidentialWinner]

Yeah this is a problem that realistically seems to be one of the biggest concerns for me. I know there is a huge open space with nearly nothing between stars (and galaxies) but an asteroid the size of 1 mm that hit us at near-lightspeed would basically have the impact of a nuclear bomb i think. How do you prevent that? Sure, we can think of some new exotic matter or shielding that could withstand the impacts but eventually you have to turn the ships antimatter engine around to decelerate and when you do that, wouldn't you have the risk of impact again? Maybe you could shield both front and backside - dunno. They touched this concept in the new Star Wars movie

[@richarddeese1991]

Thanks for a very interesting, and even inspiring video! I think one thing that people don't take into account (and indeed, doesn't get mentioned often - even by professionals) is the simple and obvious fact that if (or when, as I prefer) we *_do_* make it to some other world with a living crew - whether that world is Proxima b or Mars - living conditions are not going to be favorable! We can only go there (again: wherever *_there_* is) expecting to either stay in orbit - using any available materials from asteroids, comets, etc. - to build larger orbiting platforms such as O'Neil cylinders, *_or_* we're going to have to build closed-off habitats down on the dirt, so to speak - either heavily shielded or domed structures above ground, or dug-in structures underground. Terraforming is *_not_* a light undertaking. If we go there for the long haul, we'll end up building a LOT of infrastructure before we even begin to consider it, as it could easily take millennia to accomplish (if it's even something we can do, really.) So I would deeply and greatly hope that *_all_* aspects of such a venture would be carefully considered - not piecemeal, by this company handling this, and that company dealing with that - but with *_all_* the companies, personnel, astronauts, etc., thinking through every bit of it, and considering every angle. To that end - and I know you may not think this is your 'area' - I truly believe the first long-term, if not permanent, colony we every build should be on the Moon. We've *_all_* got to get this right! The things we learn about living on other worlds - by living on the Moon first - will be nothing less than critical for the future of space travel - at *_any_* speed, and to *_any_* location. Thanks again. tavi.

[@TeaParty1776]

> make it to some other world with a living crew - whether that world is Proxima b or Mars - living conditions are not going to be favorable! Youre ignoring alien hotel chains.

[@directedby100]

Well done. His conclusion answers a question I've always had: how can we travel beyond this galaxy when millennia would have passed on Earth? This only matters if you want to return to Earth. Multiple Earth-origin exploration civilizations could exist while being unable to have contact across the gulf of time separating them. The solution is simple, we exist independently, ontologically separated by time. So we accept that and say goodbye to Earth. Excellent.

[@truckerfromreno]

@lordhaven111 The British populated Australia by sending people in British prisons there.

[@jmitterii2]

So let's imagine: You take the Christmas M&M anti-matter matter shove it up the butt of a spaceship. Go to Kepler 452B. Get their in 12.5 years. Upon arriving you discover amazingly some civilization is already there! Surprisingly, over the radio they speak English, knowing your exact mission name and all crew on board. After 300 years on earth, discovery of warp drive technology was made; orders of magnitude faster than light speed without the time dilation. And after 1,500 earth years, already entire colonies are on the planet, terraformed and has a vibrant zoology and colony.

[@dust213dust]

after 1500 years hope humanity on earth is still alive though if we went out in space to settle colonies they might have a better chance at surviving then us here on earth

[@Daemien21]

I was thinking the same thing. Send you on a probe and another probe is passing you that was built more advanced on earth because of the dialation. You arrive there to find humanity found a better faster way and already have skyscrapers being built on it when you arrive by your great great x150 grandson. crazy talk

[@OckertJBrits]

That is bound to happen, so all the "aliens" "out there" will most likely be from earth and most likely all be within 50 years of age of each other, but due to time dilation be thousands or billions of years different in relative age - wrap your head around that!

[@richarddeese1991]

That's certainly possible. But if it would keep you from going, then you're the wrong sort of person to be sending out on *_any_* spaceship - now or in some 'perfected future' that's never gonna happen! It's the same as people who say we shouldn't do anything about climate change *_yet_***, because the science isn't perfect ***_yet_***, so we should just wait and see. What if people never spread out from Africa, because one guy said, "You know, I think one day someone's gonna invent a better way to travel than just walking around lugging everything!" We don't have to know all the ***_answers_* now; we just have to *_start_* now. Besides, it would be very, very rude of them to pass us right by, start a colony, then wait for us to get there - all without even *_bothering_* to let us know anything. And they'd *_have_* to know we were out there. Pioneering is *_not_* for the feint of heart, for sure. I couldn't do it. Then again, it's not *_supposed_* to be! tavi.

[@ParanoidFactoid]

Google "4th generation nuclear weapons". Use of micrograms worth of antimatter as a trigger for miniature fusion bombs. You'll find a research paper and an informative youtube video. You bet they're after using antimatter for weapons production.

[@DeadFishFactory]

Antimatter is inherently fail dangerous. Not good for a bomb unless you make it on the battlefield as you need it.

[@ParanoidFactoid]

@DeadFishFactory: See the paper. Magnetic bottles are old hat. The new way to store is a micrometer sized matrix of magnetic bottles, with trigger for controlled release. You only need half a microgram or so to trigger a .1kt - .25kt fusion bomb the size of a hand grenade.

[@jmitterii2]

No. First thing humans would do with antimatter is what they do with every new thing.... try to have sex with it. Then they'll make a bomb. Humans. We're fucking stupid. Literally and figuratively WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!

[@LesterSuggs]

...and the second thing humans will do with antimatter is make bigger bombs.

[@jadyynstarlight9851]

1) Like in the book "Tau Zero", you are forgetting that you need to flip around and start decelerating half-way to your final destination or you will simply fly past it very fast. This will probably increase travel time at least 2x and probably 10x (I believe time dilation is exponential). You will probably need some sort of actual shields to protect you from space dust and such in the direction of travel. 2) I believe the best "propulsion" comes from the "Philadelphia Experiment" and "Montauk Project". This is matter/people teleportation. I think I read somewhere that it is actually being used now to place people on the Moon and even Mars almost instantaneously. A ship like this can probably get to Alpha Centauri in days in several hops. In fact, I believe, we have already colonized planets around stars to at least 1000 LY WITHOUT time dilation. Look into it...

[@raykent4533]

Noone gonna comment on this one?

[@afrenchcanadiansoldier1334]

Now this was excellent, finally some discutions about time dialation and this is very profound.

[@robstock]

So a few questions I have about his time/distance numbers: 1) Is he accounting for deceleration? Or just a constant acceleration? Like would the burn be going the whole way or would they flip at halfway or so to begin deceleration? Would it have to be at the halfway point to accommodate the 1g limit? 2) If we're deciding to send people - what about a return journey? 3) Why not just send robots? Wouldn't they have much higher limits on acceptable gravity, what with no squishy bodies and all?

[@RobertsMrtn]

Great presentation and nice to know that someone is working on this but I can see a problem which does not seem to have been discussed. If you are able to perfect the technology and travel at close to the speed of light, if you hit something the size of a grain of sand, that will be enough to destroy your space ship.

I really appreciate the work that you guys are doing, and I understand that when you discussed the time needed to travel to the edge of the observable universe, you just wanted to qualitatively illustrate the vast distances possible to travel at an acceleration of 1 g. But it is actually impossible for us to travel to the edge of the universe even at the speed of light because the universe is expanding at a greater speed because of the presence of dark energy. Just wanted to clarify this so that people do not develop wrong perceptions.

[@JohnWesleyHardin1853]

"If we go at 1 g aceel we get there in 3.5 weeks ..." However, did I miss him discuss deceleration?

Jörgen no sense what you said, the expansion on the univers is not the speed of light more of the time, so you can go to other galaxies out of local, on any time soon

[@Gabdube]

The expression "hasn't been figured out yet" should never be used when making predictions. If it hasn't been figured out yet, we necessarily have no way of knowing that it will ever be figured out at all, i.e., we can't know if it's even physically possible. We can imagine lots things that are physically impossible, that doesn't mean that we could ever "figure them out".

[@fmfranchise23]

Pabloxd123 - Taking relativistic effects into account, the trip to go further than our milky way could be accomplished in 20,000 light-years from the perspective of an observer on Earth. If someone attempted it, you would never hear from them in your life time.

[@furionese]

Jörgen I thought you ride along with the expansion of the universe so the more outer edge you go the faster you’d move, along with the expansion? We currently on earth are indeed moving away from other distant galaxies as we speak, in relative to them we might be moving at the speed of light, right? Correct me if I’m wrong.

[@MrAlkyd]

That is a theory based on some highly debatable proof. If you take a close look at the proof then you'll see some holes appearing. There is a part of the scientific community that thinks that it isn't expanding or at least not as fast as they think.

[@psychedelicdreamer986]

So I guess the Star Trek idea is off the table, if you want to boldly go where no one has gone before, it would mean never coming back. Or is anti-matter just not the way to go? Space folding? Artificial wormholes? Instantaneous travel from one point in space to another seems the only way to have interstellar travel and be able to do it without time debts. As a trekkie I'm a bit disappointed.

[@xavierlumley7997]

NatalieCatLee Wormhole is space folding, but in order to make an artificial wormhole you would have to prove that wormholes are able to exist and recreate the conditions that make one. At this point they are in the high realm of sci fi.

[@ben10pa]

[@lcdvasrm]

That method was illustrated in Cosmos by Carl Sagan; it is attractive in principle. You then have to find a way to transform that mass/energy captured into light directed backward...

[@tonikotinurmi9012]

If you try Bussard ramjet (collecting atoms for hydrogen fusion) you slow down more than accelerate. i.e. no way you can collect needed atoms, perhaps onboard turn them to antimatter etc. on the way - you should still carry the mass like ordinary rockets do OR get stream of propellant somehow from somewhere for a very long time. Energy of this received propellant would diminish as the ship would get closer to lightspeed. Not to mention all stuff the ship'd hit... This guy is a fraud. He could've as well counted how many kg's of food needs to be stored for 50 years voyage ignoring all other problems !

[@ParanoidFactoid]

It's also not possible to reach high relativistic velocities, even with an anti-matter photon drives (which this researcher does not propose, he proposes conversion to charged particles first). You'd be lucky to get to 10% to 15% c with this engine. Which is pretty damn respectable. You'd be tooting around the solar system very nicely at those speeds. As long as you don't hit anything. But interstellar with that technology would require suspended animation or life extension.

[@johnwang9914]

Interstellar travel might occur without intentionally trying to do so. Primitive man migrated to six of the seven continents on Earth not be intentionally traveling to another continent but by building another village over the next hill. Likewise, if we just build Stanford Torus's, Bernal Sphere's and O'Neill Cylinders out of asteroids and comets then we would migrate to nearby stars without even trying to do so. There would be no issue of being outpaced by faster technology as the habitats you live on would be your destination in the first place and we already know there are interstellar resources as an extrasolar asteroid recently passed through our solar system. One asteroid can build and power a lot of city scale habitats.

[@jeffpatton2758]

Try Transubstantiation! That’s the key to faster than light travel, because there is no mass associated with craft and occupants. If you raise the vibration of an object, it disappears, and vice versa. The craft can be made to disappear, then reappear at the chosen destination. Virtually instantly.

There is no choice. We either move into space or our species becomes extinct. The sun will not last forever so the only way our species can survive is to go somewhere new and to be prepared to move on from there after a while. Even all this eventually becomes moot as the universe does have a limited life. But, we have got to at least try. Is there anything more important than the survival of our species? I don't think so.

[@pabloxd1239]

true, but you cant do this on this years (sorry bad english)

[@Gabdube]

There's not really a reason why we couldn't do this over the long term. Of course, we'll have to leave eventually. The sun is already at half of its life expectancy. It'd be a shame to let all Life die because we don't take its worth seriously. Preserving Life in the long term implies developing space exploration as much as possible. It is a moral obligation.

[@apolicum]

"Already" at half? That's still soooooo much time we have. I don't get why many humans now want to rush in a period of a few decades/centuries to explore asap other planets so we can save our species. We have at least a billion years to go until the sun's expansion will be too big. A billion years is so incredible long, that if evolution would have started a million years later, we still would say we have more than enough time before the sun dies. So actually the next million years (and even much longer) we can take it easy and no need to rush.

[@Muuip]

Exploration is one of life's purpose, it shall be done synergistically while helping people in need here on earth (for example build housing for poor people living in extreme environments, hot or cold, to help perfect housing designs for other planet). To travel light speed we will have to travel as informations in a laser beam which can trigger matter in an other planet to form nanobots which in turn form robots. The next step is then to upload ourselves as informations into them. AI will be us uploading ourselves into avatar robots (transcendance). As for spacetime, I understand it as the perception of it to be relative. Time is based on the rotation of planets, so travelling light speed won't change planetary movements but change our perception of time on earth, which will come back to normal during the return trip.

[@itinerantpatriot1196]

As a Trekie, the notion of intra and interstellar travel fascinates me. But the distances are so immense and the effect of time dilation so extreme that it puts a whole new twist on the term: "Live long and prosper." Man, you gotta REALLY live long to prosper on that flight. Unfortunately, I just don't see us cracking the code unless we can figure out how to cheat time itself. But I absolutely believe asteroid mining will be a thing in this century. I do wonder if a large influx of precious metals will drive down the value to a point where the law of diminishing returns will kick in and make the effort not worth the trip but I'll be honest, I got a B in economics so my concern could be way off base on that one. Cool talk.

[@callummacleod3146]

There's nothing faster than light though

[@johnwang9914]

Technically, laser propulsion of light sails could easily out accelerate an antimatter drive so long as the light sail could still be targeted by the laser which brings to mind the concept of laser relay stations to establish a highway in space. Remember reflecting light doubles the momentum you receive and with sails you do not have to carry the energy source not the propellent mass.

[@mgm553]

Callum Macleod he didn’t say faster than light he said faster than light sails a light sail travels at 20% the speed of light. Also things can travel faster than the speed of light. Everything past the edge of the visible universe has accelerated to faster than the speed of light hence why we can’t see it

[@iholarabaybay]

Zach Smith which things can travel faster than the speed of light?

[@mgm553]

Julio Giron nothing can travel faster than the speed of light in a vacuum but the universe itself is expanding faster than the speed of light causing everything within the universe to slowly accelerate to infinite speeds, everything on the outer edge of the universe is expanding faster than the speed of light so we can never see it again because the objects themselves are traveling too fast for the light to catch up to us

[@gamestv4875]

Enjoy and take care of this planet. It's our only home and always will be. The sheer numbers and distances is mind boggling to say the least. By the time we have the technology to become "nomads" in outer space we would already be extinct either by wars , climate change or by some other extinction event. You cannot compare being "nomadic" on earth to being a "nomad" out there.There's huge hurdles to overcome.

[@buffalorick8769]

I would imagine the concept of PERPETUAL MOMENTUM would be a very good way to get high speed into outer space. But it could not be manned because we would have to keep our fingers crossed NOT TO HIT AN ASTEROID AND DESTROY THE CRAFT. So Perpetual Momentum, Sir Isaac Newton at the wheel

[@TL-fe9si]

Even if we have anti-matter propellant, how to maintain 1G acceleration when the spaceship's speed reaches near light speed? Wouldn't it take almost infinite amount of energy?

[@audioartisan]

Or even "slowing down" before arrival lol

[@a3iuuu]

What about inertia?

[@WackyAmoebatrons]

No. In the ships rest frame, for one g acceleration, you always need the same amount of fuel per unit time. However, seen from the earth's frame of reference, the ship will accelerate less and less the closer it comes to c.

[@EinSofQuester]

Yes, the faster you go the more antimater/matter per second would be required to maintain the 1 g acceleration.

[@tomctutor]

@@WackyAmoebatrons CORRECT.

[@RichardScholar]

So, if we send someone on a near light travel to another star... won't we beat them to it? To them it would take years... but to us, we would have enough time to figure out faster then light travel and get there before they ever do.

[@supergps2000]

That''s like inventing a race car after race has started, and then winning in that car.

[@supergps2000]

That would work onlty if new physics allows us to build the winning car.

[@RichardScholar]

Yup! Bending time space would allow us to get there quicker then someone going near light speed travel by leaps and bounds and we would have 150 years to beat them there.

[@supergps2000]

Someone travelling at speed of light is already going to reach there instantly (per their ref frame.) If I am second traveller that starts with new faster physics, i must be at both the start and destination at the same time before my travel starts, or in other words, I must be travelling back in time too? That sound correct?

[@RichardScholar]

supergps2000 did you watch this video? Someone traveling 80 percent the speed of light with current technology will take just under a decade to reach our nearest star. People on earth would observe those travelers as taking 150 years to get there. The travelers will experience time around them speed up while they remain un-effected. They will personally experience 8 years of time while everything 80 percent the speed of light slower then them experience 150 years. They will get to there destination 150 years later but would only experience 8 of those years. They are traveling through space so fast that they also travel through time at an accelerated rate, hints Time Space. Idk how else to explain it. We have 150 years here on earth to beat them there by learning to bend time space and get there in just days without experiencing that same time dilation. Hell, they might be arriving to a future human settlement.

Is he proposing producing anti-matter on Earth and storing it in the spaceship or is he proposing creating the anti-matter while flying? At one point, he was talking about using radioactive decay to create anti-matter. If he brings that radiation source with him, he won't get any more energy than using the radiation source directly as a source of energy. You need to hold back enough fuel to stop the spacecraft when you reach your destination.

If the light from edge of the universe take billions of light years to get to earth, how does a speed that is slower than light speed make it quicker?

[@spencerdalling2559]

We haven't seen the edge of the universe yet since it's traveling away from us faster than the speed of light. I believe what he was trying to communicate was the relative time dilation as a craft begins to near the speed of light, people in the craft should experience less time passing than the people left behind on earth and as the craft nears the edge of the observable universe, people in the craft may have experienced as little as 30 years whereas earth experienced 13 and a half trillion years. According to Einstein, the closer to the speed of light you get, the more your relative time dilates. So, relatively, time may come to a standstill for you as you near the speed of light as time goes on like normal down here on earth.

[@bennemann]

It takes billions of years in OUR time reference, but for the photon, it takes no time at all. If the photon had a conscious mind like ours, it would have experienced to have arrived on Earth instantly, because at light speed time does not pass. The edge-of-universe spaceship would experience 30 years, instead of no time at all (like the photon would) because it would be travelling at 0.99999999c, and not 1c.

We wouldn't be going at the speed of light for a little bit until we pass it.

And as you continue at that acceleration, you'd get closer and closer to c. But well, even at 0.99997c, you do and you don't get 1500 ly away in 12 years.
