- Meet a true explorer who might lead humanity to make interstellar travel a reality by developing the world’s first antimatter rocket. Through his fascinating speech at TEDxDanubia, you will have an understanding on how positrons meet electrons to reach an energy level to travel faster and farther than you could ever imagine.
The 31‐year‐old Air Force pilot is Co‐founder and CEO of Positron Dynamics, the company that is pioneering the use of antimatter in space propulsion. He has a BA degree in Physics from Wesleyan University in Connecticut, a BSc in Engineering & Applied Physics from Columbia University, New York, a PhD
from the Centre of Excellence in Antimatter Matter Studies at the Australian National University and is one of 13 fellows at WIRED 2015 Innovation Fellowships recognized for his work in antimatter propulsion.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx
"Do you want to be nomads again?"- Question thrilled me..
yes, and a couple of new empires
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
Yes, very much so and a pirate too.
Absolutely
Yes..most likely bicycle touring this planet first..
This man deserve a huge amount of respect for what he has already achieved.
Regards, Geoff. Reeks
Absolutely, his patent is viaible and big corps will soon be trying to cash in.
Which is what, exactly?
Deserves*
I havent met him yet. If i do ill thank him sir. I believe you both
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.
it's people like this, often behind the scenes (getting evicted by nervous landlords!) that are inching humanity towards fantastic possibilities. Sir, I salute you.
I'd like to see your plans on dealing with dust particles moving at a good fraction of light speed relative to the ship.
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?
Simple your spaceship' mass has increased (relativistic mass) compared to dust particle - so it would obliterate said particle (Voyagers still there 40 years later)!
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).
@@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.
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.
I love how this comment section knows more about antimatter than the guy with a PhD in Positron Physics XD
M. Woller What do you mean???
Armchair physicists are the worst!
Duh
Awesome man I really appreciate you
😂
I would like to invite Mr.Ryan Weed to my country. We can not contribute to your idea and project, honestly. But we need human beings like you to enlighten our people.
Everyone here is talking about the video, I'm just staring at the title wishing my last name was "Weed"
You do have a interesting name ''GOATPIXEL'' you don''t need ''weed''
oh thats good thats good
That is actually the first thing I saw when I clicked on this video^^ fking golden!
Goatweed !
LMAO
i can't get over how profoundly useless and utterly pointless my job is.... selling lamp shades.
nneerraajj2903 ahaha.
Bruh 😂
What a lightbulb moment!
Rolan get off the stage!
Why don't you quit your job and do something good instead? Seriously? Unless you somehow already shackled yourself with responsibilities, the only limitation is your mind.
imagine flying in your little antimatter spacecraft in space and then more advanced human spacecraft overtakes you and they laugh at you from the window. or could they even do that i wonder?
scanjett lmao
scanjett lmao was thinking the same thing haha
Wouldnt the overtaking space craft be only possible because of incremental advances from the first space craft?
and then you both stop at the traffic lights
scanjett we cant even make autonomous vehicles work
Incredible..and he explained all those in such a simplistic way i understood exactly everything he said. I have zero scientific background or self study on these matters.
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.
> 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.
Seriously though.. if humans weren't so petty and we worked as a species instead of killing each other and dividing ourselves into nations and religions, we'd totally have a manned base on Mars by now.
But they want to spend all the money on the false-flag wars they've created... PROFIT
bit of a stretch tbh
if it werent for the space race, and the cold war, we might not even have space rockets
@@TheBoeboe I don't believe that. Humans were looking towards the stars way before the war. If anything, all the wars only slowed down the inevitable discoveries.
@@SuperRambo111 completely disagree... competition in most instances, equals improvement.
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.
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!
You nailed it. We are explorers...always have been. Going against that, is what is causing so much unrest. We don't have something to focus on as humanity....so we spend our time focusing on ourselves, and that's a bad idea. We are all flawed. Let's get back to exploration, and give humanity hope and something to focus on.
I encourage everyone to watch "Best method for Interstellar travel"
My takeaway: THAT'S why it was so critical on the Enterprise that the Antimatter Containment Field didn't fail. Thank goodness for Scotty.
all we needs is some dilithium crystals
And why they had an emergency system to jettison the core if it was losing containment.
The first thing humans would do with antimatter is make bombs.
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.
Antimatter is inherently fail dangerous. Not good for a bomb unless you make it on the battlefield as you need it.
@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.
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!
...and the second thing humans will do with antimatter is make bigger bombs.
Now this was excellent, finally some discutions about time dialation and this is very profound.
This will ever remain a dream. One can be happy with the imagination, just that.
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.
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
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
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!
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.
Yeah, but it's job security for 12.5 years.
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.
Yeah, that alone makes this entire TED speech a complete fraud. Faster than light travel is only possible through wormholes.
I've wondered about the same thing. You are bound to hit some asteroids here and there. It's not just "smooth sailing".
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
ever heard of auto pilot?????
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
14:42 that awkward moment when you want to give a standing ovation but nobody else is standing so you chicken out.
The best thing we can do is work on cryo pods and research more about induced hypothermia.
We humans are curious, creative and highly imaginative beings. If only the earth was united as one, we would have long become a type 2 civilisation and would have explored a lot through space.
We're not even at Type 1 yet. Type 2 is estimated to be about another 800 centuries in the future..... We are nowhere close to harnessing all the energy of our sun, and no amount of unity would have changed that.
> If only the earth was united as one,
The Nazis tried that. It didnt work out.
Note to self, listen to Mr. Weed.
You can get to the Edge of the Universe in 30 years? So if you turned the ship around in, say, 10 years, you could come back and see the Earth several billion years in the future, assuming it still exists then? Mind blown...
Ryan Blais the sun would have probably decimated the solar system by then lol
It would take 46.7 billion light years to get to the edge of the universe. His math is wrong
30 on the ship bt billion years will pass on earth
'Decimated' means something was reduced by 10 percent. I think you meant 'Annihilated'.
Yeah makes no sense.... If its possible to bend Time and Space and travel somewhere else instantly then time shouldnt move at the Solar System... That ship should be able to back and forth using the same amount of time...
Buenas noches , todo con mucha lógica y muy natural y sobre todo muy interesante la informacion que habla el Sr:Ryan Weed. volver a empezar la vida de nuevo .
I can't believe I'm only just seeing this video now 2 years later, this relates to my book I've wrote, and this ties in with the Fermi paradox, kind of solves it really. But it justifies my book entirely on why we need to survive as a human race, although Ive said in my book we need to travel. We need to sort out earth.
In short you are a legend Ryan Weed, and you have explained the Fermi paradox.
Did he mention Fermi Paradox here, might have not sure?
I feel bad for the next planet we find to live on..
StuuDude well its not living so it doesnt matter and its only 1 of trillions and trillions and trillions of planets in the infinite universe, so sure feel bad
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.
@lordhaven111 The British populated Australia by sending people in British prisons there.
Those last words both gave smile and tears
we marvel with awe at the builders of ancient buildings & cities which we can't duplicate or replicate yet we seek to travel across the universe. dream on!
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...
Noone gonna comment on this one?
Man why is the crowd so dead I would be cheering hard for this guy
Somebody should have checked his math before presentation. I think he may have used rocket speed for his calculation because covering the first and second distances only take 38 and 116 days not months and years respectively.
How can this thing that we don't even understand be what helps us travel the fastest?
Just glad someone is thinking along these lines.
Big want. This idea is so awesome and exhilarating
I can understand this because I already watched Rick and Morty
people like you make me believe in humanity.
Regarding his question at the end of whether we want to be nomads again... I would gladly be a space nomad, so long as I had all the comforts. Or a space viking? It's a nice fantasy.
Very interesting talk, I enjoyed watching this video.
18 y/o from Ireland. Brilliant talk 👏👏👏
I'm high, wondering about this question, looked it up, and this guys name is perfect!
I’d volunteer to be sent out, never to return
I'd only go if I was promised I wouldn't have to return. ;)
WOW! On so many levels just wow!
Amazing man what an amazing speech
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.
> universe is expanding at a greater speed
Then you need a really fast ship...
I like how he doesn't mention deceleration... that greatly extends the time required as you have to slow down by aiming your thrusting apparatus in the opposite direction presumably with even more thrust and g forces than the acceleration if you don't want to start deceleration at the halfway point.
Not if you bend space you smuck
Everyone here has a PHD hahahahah
Excellent talk.
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?
"If we go at 1 g aceel we get there in 3.5 weeks ..." However, did I miss him discuss deceleration? Not only do our theoretical explorers have to factor in decel, but as so many others pointed out, all life support mass and propellant mass would have to be considered.
Realistically, there can be no interstellar travel unless/until some means of FTL is discovered and safely applied.
It is amazing that Elijah Wood found time to focus on space travel after his acting career
We have to explore by ourselves. We cant send probes! This is the most awesome message.
Well this was an eye opener
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.
You know this how? Lol 😂
A very real problem that they've already had to tackle with the ISS and space probes. I know the ISS uses an orbital debris shield, but travelling interstellar at light speed poses it to be a much greater problem.
A force field around the ship. Dont you read sci-fi?
@@UTINNI_36 Horrible take to be honest. F=MA
12:30
Is the calculation to Alpha Centauri with or without slowing down?
Silt Strider
With, I think. He goes on to say that 5 yrs pass on the spacecraft and 9 on the Earth.
Silt Strider
Iirc at 1g acceleration you reach 95% c in about 360 days, so that's 2 years to speed up and slow down.
A coffee break and three other stops with a short layover
A very good point, no one even considered that here but you. Half way the spaceship would have to turn around 180 degrees and reverse thrusters, still 1g though so maybe his calculations out by a factor of 2x.
This dude has to back it down a notch. We only just figured out the logistics for overnight shipping about a decade ago.
11:48 Dudes strugglin to stay awake, I miss those nodding off days of highschool lol
"Do you want to be nomads again?" - The movie Passenger comes to mind

Wow when you put it like that.. home seems like a good place to be..😎
I would and I bet tons of people would be happy to given the right circumstances. Maybe its time for another kind of adapt/ evolve scenario.
Given the chance, I would definitely embark on something like that, it’s a once in a lifetime opportunity, imagine that, being among the first humans in another system, galaxy.. if many worlds are conquered over a timespan, one day humans can become the first (maybe) sentient beings connected by multiple interstellar - planetary communities. That’s a sentence you don’t say everyday lol

Interesting take at the end there...
😂😂 the man at 1:58 already knew he was in for a long ridiculous talk
I literally came to the comment section to see if anyone talks about this guy lmao... Nice!!!! (y)
No... He's just camrea shy 😦
It's because nobody laughed at the joke hahaha. Facepalm
well let's face it, anytbody that re-ups for yet-another a "TED TALK" knows the punishment they are gonna get
Similar mood to the guy at 11:48
It is dishonest not to talk about the propellant mass needed for relativistic speeds. Even with antimatter.
lcdvasrm yes that is worrying
lcdvasrm maybe the ship can collect it from free atoms in space? I dunno
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...
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 !
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.
Interesting video with a lot of clearly explained physics concepts. Is there any way to find a warp hole or somethin' so we can travel there without the time dilation thing?
He’s such a hunk! I understand all the science he’s talking about. I have four degrees. It’s just nice at my age to see a hunky guy helping to educate younger people.
He doesn't look that great to me what are you talking about.
This guy looks like a young Rodney Mckay :)
The universe is expanding, even at near light speed travel, mankind can't reach outside the local group.
So the example of reaching "the edge of the universe" is a bit strange if he haven't invented a real warp drive :)
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
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".
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.
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.
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.
keep exploring sir.
I learn alot of diffrent things from this channel
An interesting sci fi idea would be: an exploratory vessel was sent out 1,500 years ago to Kepler B. Now it's coming back. Follow the struggles of the crew reintegrating, and the people on Earth in adjusting to what they brought back. Because they met aliens. They shared some technology. But in the meantime, Earth has progressed as well. So now Earth is, say, beyond the concepts of monogamy and gender and sexuality, so it's like the crew are from the 1860's coming back to the 2010's. But they have technology Earth doesn't have, and can create a post-scarcity society. Maybe also throw in there's no such thing as privacy anymore and does the crew want to hand the technology over to an invasive corporate government? Lots of ways to take it.
J.T. Seusoff You should write an outline of that story then flesh it out and then write a book. Very original sci fi story
D'aw, thanks! I've got pages of undeveloped ideas I plan to one day run as tabletop RPGs perhaps-but-probably-not. That will probably just join that document for decades.
J.T. Seusoff to be a Hollywood blockbuster, they'd have to come back pissed off at what we've become and use their advanced technology to reconquer 'their' planet ;-)
To J.T Seussoff - there already is a sci-if classic that tackles this very issue written back in 1974 - Joe Halderman's "The Forever War"
J.T. Seusoff- Are you high?
Why does no one ever bring up the fact that it does not matter how fast you travel, you can't travel in a straight line..... eventually you would hit a planet or debris.
I would love to save up for space travel! I would rather see more and experience more so my next generation can see it their lifetime.
This is literally Luxemburg‘s biggest passion and interest - THE SPACE!!!
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.
Ditto
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.
Yes, I know. Unfortunately it's still scifi and the only place we'll be seeing it in our life times is in fiction. I don't know if you read the book series "Hyperion" by Dan Simmons, he has some interesting ideas about these subjects, great read.
I think it's also important to keep in mind that Physics is a relatively new field and though we may not understand it well enough now to travel fast, one day we may.
Our bigger problem is even if we come up with technology human meat bags have short life expectancies and they do not handle the high energy radiation discovered by voyager outside of the heliosphere. We are more suited to living under water than we are to living in space .... and we have hardly mastered this yet. after all we have zero colonies under water... why not?

Interstellar travel
Sounds cool !!!
Awesome 👍
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.
It's 2019 and he said it would be about two years for that small satellite to get into orbit. Anyone have any news on how this project is going?
It's going okay.

An hour before I thought I was a serious man. Now I'm watching a guy who's name is Weed talking about interstellar travel to the end of the universe that he believes to be possible by an antimatter drive that he started doing in the office before he moved to the nuclear fallout shelter and he seems to be quite reasonable to me. Should I worry about myself?
The universe is a strange place, but life is even stranger, stranger. :) tavi.
Is he trolling us ? It takes (93 Gly) 92936344969,19946 YEARS FOR LIGHT ITSELF to even reach the OBSERVABLE universe, how is it possible for us to reach the EDGE of the universe with a spacecraft in a LIFETIME ?

Great talk ... the answer is, yes.

Anti-matter: It wouldn't matter.
This is like discussing time travel - all you need is a time machine!
I think we will learn to compress space in front of a craft and expand space behind a craft and go much faster than light speed .
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?
Or even "slowing down" before arrival lol
What about inertia?
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.
Yes, the faster you go the more antimater/matter per second would be required to maintain the 1 g acceleration.
@@WackyAmoebatrons CORRECT.
*if everything goes well, we can have the first pictures of Proxima b in 2060, hopefully sooner if something faster than light sails is created or discovered*
There's nothing faster than light though
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.
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
Zach Smith which things can travel faster than the speed of light?
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
I like the stats at the end
fascinating !
Imagine millions years later, all good planets in Milky Way colonized by humans without any space bending stuff. Тraveling faster than light impossible, thus there won't be any interstellar community, All colonies will on their own like separate civilizations with own history and culture. They will only receive messages from other colonies sent. hundreds or thousands years before. And eventually they will forget what planet humans came from or maybe some civilizations will not.
Pawel Zybulskij FTL Travel is possible. Not velocities but speed. Wormholes and warp technology.
Pawel Zybulskij maybe that’s how we got here and we are in a 10.000 year dejavú?! Von Däniken tends to believe that... (were the gods cosmonauts)
Who says FTL is impossible? Einstein? He was wrong. According to Bell's theorem (proven by Aspect et al 1981) either FTL messaging is possible OR the universe is self-aware down to each and every particle
Maybe that already happened, that's how we got here, and the flood made us forget...
Halo
I just watched 3 videos about interstellar travel, and in each of them they mentioned a different vehicle as the fastest thing humans have ever created.
And you also created Avatar?
By any chance, was one of the other two a manhole cover flung by a nuclear bomb buried underground? Though not necessarily a vehicle, it is the fastest object we've ever created (even if done so unintentionally).
very nice speech
Hello i watching your all videos which are fantastic
