Inspired by Gene Roddenberry’s Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible? Can we "warp" the fabric of reality so that we can break the speed of light? And why is NASA actually exploring this potentiality? Join Matt on this week’s episode to learn the physics of what's physically possible!

If we need such large amounts of negative energy, suggest we farm most RUclips comments for the power source.

It would be a real bummer to launch in the first sub-light starship and get to your destination to find a 100 year old human colony there because warp drive was invented 10 years after you left.
Something like this was depicted in a Heinlein novel, Time for the Stars.

4:35 Hawking was salty cause no time travelers showed up to his party
srivatsasa1 Or they did and warned him that time travel shouldn’t be meddled with. So.. he’s against it.
@@codykyzer7064 If I was a time traveler, I would definitely have gone to Hawking's party.
First time traveler from not so far time in the future almost arrived to his party before another time traveler from far more future time stopped / killed him before he reached the party because the second time traveler knows and experienced the destructive impact that the first traveler would have made if he showed up to Hawkings party.
Brilliant.
Hawking attempted travel himself to save his lost years but upon realizing that the universe itself has contingency plans in place to prevent the alteration of a time line he accepted his fate.

@@Argentvs No, prof Fansworth.
So in the attempt to figure out how to make the Enterprise from Star Trek we also come up with the Borg trans-wrap tunnels and the TARDIS. Wow, that was easier than I thought.
Wut
Jacob Thomas In Star Trek you've got the Borg that use trans-warp conduits to travel faster than warp 10, the speed limit in star trek, and it's kind of like the warp tunnels that were talked about in the video. memory-alpha.wikia.com/wiki/Transwarp_conduit
+kokofan50 Don't forget, we're making these trans-warp tunnels via Star Wars Hyperdrives.
+kokofan50 Well Star Trek is a bit iffy when it comes to it warp 10 speed limit.
Warp 10 could mean infinite speed as in you would occupies every point in space at that speed. If we go by this scale then a trans-warp conduit would not make you go faster then warp 10 but you could always travel closer and closer to warp 10. In this scale 9.9999 warp would be several magnitudes faster then 9.99
It has also been just a very fast speed with in some scale ships being able to travel faster then warp 10.
+kokofan50 I totally forgot that the Borg did use tunnels to cut across space........and even time in that one movie.
Once we figure out warp drives it'll seem so obvious that we will wonder why it took us so long.

Why is everyone ignoring the obvious?
Just build a dilithium chamber, find some dilithium crystals, refine them, find the vibrational energy of the crystal, then use a warp core to produce a matter/antimatter reaction, increasing the pressure inside the warp core chamber until you have enough to channel it to the warp nacelles.
Then all you have to do, is simply create a Gravimetric Field Displacement Manifold.
Easy.

The belief that travel faster than light can be useful to travel backwards in time is due to the Lorentz equation and the interpretation that some make to the square root of a negative number.
However, when you travel in a bubble warp you're not moving and no matter how fast trip bubble, simply no time dilation.
That is because your spaceship remains static within a region of space called warp bubble.
While you remain inside that bubble will not notice inertial force, or acceleration, or movement, or time dilation and of course no negative numbers in the Lorentz equation. :-).
It is the bubble who moves, not your spaceship.
Oooo. Pooo!
imagine you could create a bubble of air on earth and go faster than the speed of light around the earth, many times obviously. you would travel foward in time/ same thing with this.
Juan José Valero true. But the thing I have trouble reconciling with is the fact that motion is relative. If you pass by a stop sign at rest and your driving at 60mph, then it’s equally as valid to say that your cars at rest and it’s the stop sign along with the rest of the world that’s moving at 60mph.
Therefor if you were to say that your stationary and space around you is moving at C then isn’t it also valid to say that the space is at rest, and your moving at C?
@@jeremiahnoar7504 hello. The movement is with respect to the local space. If a spacecraft is moving at 250,000 km per second, it is the crew of that spacecraft who suffer the dilation of time.
That is to say, when they return they will remain young, and we old. But on the contrary it does not happen.
Since English is not my mother tongue, I don't understand where the relative movement you mention comes from. But I just saw some episodes of the Futurama TV series and I think I understand what you means.
The Alcubierre metric has nothing to do with the Futurama spacecraft. In Futurama the ship remains stationary while the entire universe is moving. That is fantasy.
Alcubierre's metric is something else entirely. The spacecraft also stops without moving relative to its local space. The local space is the warp bubble. And it is the bubble that moves.
It's kind of like riding a surfboard. It is the surfboard that actually moves, and the occupant is standing still on the surfboard.
Steven hawking's idea is based on a need to prevent backwards causality. He himself admitted there is no real evidence such a "law" preventing it exists, it was just his belief.
There are ways to allow backwards time-travel without creating paradoxes. The best IMO is the
Novikov self-consistency principle.
Yeah, there's nothing inherently wrong with time loops.
Although if your universe stopped existing once you start a time machine, that would explain the Fermi Paradox.
@@MrCmon113 The fermi-paradox isn't a huge deal IMO.
We don't know the probability of life randomly forming from chemistry, it could conceivably be so low that it only happened a few times in the entire universe. We *are* talking about a soup of chemicals building a self-replicating machine after all.
We also don't know the probability of life becoming sapient. High-tier animal intelligence seems to have emerged independantly multiple times (corvid birds, elephants, cetaceans, and apes) over the course of the last 500 million years of animal life but sapient beings have only appeared once.
So maybe life is everywhere but sapience has only happened a couple times.
There are lots of answers. It's not much of a paradox.
I can appreciate that you took the time to say "Check the description for the source information"
I still have confidence in you, humanity! I believe you can do it within my lifetime!

Benjamin Antman We can do it. Not them. You are a human too. If you put everything on other humans and you say you're out, nothing happens. I really hate this you won't believe me.

@@munchymccrunchy6611 Did you just assume their species?
grodhagen lol we’re going to mars in like 5 years
If we do make it within 40 years, it'll definitely be due to Artificial Intelligence. The faster AI develops, the faster all our other tech will develop.
But of course, such an advanced intelligence could easily annihilate us if we're not extremely careful. So that's the potential downside of AI.

I am so glad to hear you say it is going to take centuries as whenever someone states such a sure thing it seems the universe goes out of it's way to prove them wrong.
This channel is incredible. Thank you for providing such interesting information.
really, what that appears on it you find it difficult or impossible to believe?
Much of this video was excellent as usual for this channel, but unfortunately the part that was sourced from White's ideas requires correction. I'll go through in order:
*Thicken the walls*
That's not something you can do. This is in fact the entire reason why the energy requirement was so unreasonable in the first place. Alcubierre didn't choose thin walls for aesthetic considerations. He was no dummy and knew that thicker walls would reduce the energy requirements but it turns out that there are conditions on how much negative energy you're allowed to quantum mechanically make that require the wall to be thin. Simply put, you most likely *can't* lay out negative energy in a thick doughnut shape.
*Oscillate*
Frankly nobody believes spacetime can be "softened". This particular conjecture by Harold White is baseless.
But anyway, none of this really matters: Van den Broeck's trick reduces the required negative mass was reduced to a few grams without need for magical hypothetical science fantasy nor breaking the rules of the game, so White has a few orders of magnitude of catching up to do.
*Warp field experiments*
As far as I can tell, he actually thinks that by charging a capacitor he's making negative energy. It makes sense: otherwise, he would've used a lead ring, or filled the ring with a heavy fluid instead of charging a capacitor. Because of E=mc² anything like that would create distortions of spacetime orders of magnitude more intense.
My guess is that he saw a description of the Casimir effect that included the words "parallel conductive plates" and thought that the capacitance was the relevant physical phenomenon instead of quantum fluctuations, so he thought he'd see the effect simply by grabbing the largest capacitor he could find.
*Intriguing results*
Hardly: the data he presented was extremely noisy and the "signal" extremely tiny. He didn't present any statistical analysis of his results to show that in fact what was seen was statistically significant, and since looking at his graphs it all looks like noise I cannot even begin to be intrigued until I'm shown an excess of at least 2 sigma, preferably 3.
My tip to all of you who may not understand this field very well is to completely ignore Harold White. He misunderstood nearly all of the relevant science in several fields (his EmDrive is also nonsense -- a story for another time), and his work does not deserve to be quoted together with Alcubierre's, Krasnikov's and Van den Broeck's. These latter three are serious researchers doing serious work in a fascinating field, which I don't want to see diluted by over-enthused media-addled crackpots.
+Vacuum Diagrams Thanks for this thoughtful critique. I very much appreciate the input of someone genuinely well versed in the field. I certainly didn't suspect that White supposed that his capacitor was in any way producing something like a Casimir effect; hence our note that they use to positive energy, which of course is accurate for a charged capacitor. I'm afraid I avoided discussing Van den Broeck's conclusions because they indicate the possibility of only sub-light speed warp bubbles, which sort of defeats the point.
PBS Space Time "I certainly didn't suspect that White supposed that his capacitor was in any way producing something like a Casimir effect; hence our note that they use to positive energy, which of course is accurate for a charged capacitor."
I know, right? It sounds absurd. However, if you look at his slides, he describes his setup as if he's really creating a very tiny warp bubble in his lab, which of course he couldn't without negative energy. But now that you mention it, I don't know whether he thinks his setup produces negative energy (and therefore an Alcubierre-like metric) or that a positive mass distribution is enough to create a warp bubble as opposed to an ordinary gravitational field (which we know not to be the case even for subluminal bubbles, c.f. gr-qc/0406083). His error could be either, but I think it's more likely the former.
"I'm afraid I avoided discussing Van den Broeck's conclusions "
Oh, what I meant by "Van den Broeck's trick" is the technique you discuss in the video for making a patch of spacetime whose internal volume is much larger than you would expect from its surface area. It's actually been a while since I went through all of this so I'm a bit rusty, but you are right that he did publish another article discussing issues with a superluminal warp drive. That being said, if you were to discuss everything people published saying you _can't_ make a warp drive we'd be here all day. But since a general proof is unavailable, it's always conceivable that some other similar metric somewhere would avoid the problems. Krasnikov has a neat little paper on the loopholes of these arguments at gr-qc/0207057, if you're at all interested.
It's crazy how little we know about these things, even after 20 years (longer if you count wormholes).
PS: Last night it was late so I neglected to source my statement that the walls cannot be made thick. As a matter of completeness, I do so now: /gr-qc/9702026
+Vacuum Diagrams Where did you learn all this stuff? I'm kind of new to this field but I would certainly love to learn more about it.
+Vacuum Diagrams That seems really strange; I'm pretty sure NASA knows what capacitors do, although who knows what politics are behind internal funding. I can only assume that Eagleworks proposed a number of much more serious programs to get initial funding. This particular experiment doesn't look especially expensive, so I imagine it folds quietly into operational costs. Same with the EM drive.
Now you could of course pass a laser between real Casimir plates, however I imagine that the interference produced by the Casimir slit would make interferometry impossible. At any rate the expected curvature effect would be even smaller than the already unmeasureably tiny Scharnhorst effect.
Thanks for the link; yup, I'd seen that. Do you really think that the TARDIS bubble is plausible? I took it as another example of "making up a solution to the Einstein equations".
PBS Space Time That is strange. It's possible that NASA doesn't have that many people versed in quantum field theory (since it's not needed), so they just rolled with it. However, they have been funding some pretty outlandish and almost certainly wrong projects for a while now (c.f. their "Breakthrough Propulsion Physics" program), so it's possible they did it intentionally. Maybe they have a policy of throwing money at unrealistic projects that sound vaguely plausible if the potential gains vastly outweigh the cost. We may never know.
About Casimir forces, that's very likely, yes. Even measuring the energy density takes extremely precise experiments, and that's without a factor of G/c^4 in front. They're almost certainly undetectably irrelevant to gravity. If negative energies are at all useful to something like this they have to be generated through some other means. Visser suggested a massless scalar field non-minimally coupled to gravity. It works, but it's not much more than cute speculation.
" Do you really think that the TARDIS bubble is plausible? "
Eh, at least as plausible as all the other things here, which is, as you say, not very. There's one extra problem though: to reduce the energy requirement down to something sensible you have to make the throat of your "TARDIS bubble" extremely small, close to the Planck scale. That's almost certainly impossible.
I want to believe

They could enslave us, bully us into their annoying alien culture and make us submit to abandon our own. And endless suffering without a chance of being exterminated by natural factors because they have too much high technology to prevent that... just imagine what we would be like to any maturing alien civilization? We are very annoying!!!

There needs to be more SciFi written with STL travel ^_^
Rimworld is a game with only STL tech, inspired by firefly. If nothing else, check out the lore, it's pretty cool!
I recommend _Aurora_ by Kim Stanley Robinson, about a generation ship in STL travel to another star.
+neeneko The Left Hand of Darkness by Ursula K. Le Guin.
Ender's Game, and most f the sequels. The thing with STL travel in fiction is that it really handcuffs the writer. The characters can never return to somewhere they were, because that planet is now centuries in the objective past. So unless the plot is strengthened by those vast gulfs, it's going to make things harder to stay immersive.
+Joshua Pearce Egan Greg and his books "Diaspora" and "Incandescence" create a great setting of STL-starfaring civilizations. In both cases those civilizations are mostly made up of AI-like beings (mostly former organics who transferred themselves into computers) that a) immortal in most regards (it's hard to destroy someone made out purely of information that can easily travel from one computer cluster to another) and b) reprieve the time differently, so it's normal to be apart from your friends for 10'000 years and then meet up and hang out like nothing happened.
It makes it hard to wrap our human minds around those concepts sometimes, but eventually you get the hang of it. Very much recommended read in any case.
They no longer need the warp drive "highway" in more recent formulations. Also, FTL travel only causes time travel in the interpretation of GR that is most popular among physicists due to its mathematical elegance. I wasn't aware that they had a version that could get down to grams of negative energy...pretty cool!
Most likely the 'the more we know the less we know' problem (namely that the so called universe is quite literally "queerer than we CAN imagine" ) will deter physics of the 'real' world and transfer the intelitgensia (as close as possible to integrally) into cyberspace, where not only we may but DO know the rules. The distinction (between real and virtual) is materially irrelevant, a philosophical error. We might, and I daresay will, learn as much about the 'real' universe from cyberspace (in both senses) as we fail to do from 'here'. Big data exponential growth will turn into 'bug data' and by then real world analysis 'as is' will become entirely obsolete. Exponential growth of knowledge will, probably, remain spawning and sprawling more unusable knowledge, exponentially, otherwise. The physics of tomorrow will not merely utilize computer science but become it.
I would love to see a follow-up video on a warp drive's impact to objects that are in its path, or near to its path. Sure, we can theoretically bend space and time to travel the universe, but this method isn't a benign, self-contained, super gravity bubble. Our warp drive will impact the orbits of celestial bodies, the trajectory of comets and asteroids, and may turn out to be a force leaving a trail of destruction in its path. Our drive will temporarily change the fabric of space-time as we pass through, but the after affects will be permanent. This would be an interesting topic.
I'm really excited of this amazing future technology
This is a public question: Do you think if Einstein was still alive at this current moment, do you think that he would advance us in space travel?
Nope.
+UpToYouOnly I believe he would. His brain's capacity wasn't limited to his time, he was limited by how far science had already taken us. Once he was acquainted with modern theories, I honestly believe he would've gotten right back to work at the same capacity relative to our time.
+Nick Mwakajumba There are far more intelligent and capable scientists than Einstein. Tesla in my opinion has got to be the most intelligent person to live.
+UpToYouOnly Do we not have his brain some where? Lets clone him and ask him :). I mean we clone cows and sheep all the time so it cant be so much harder to clone a human.
+UpToYouOnly He developed his ideas in his youth years. He spent the last of his life trying to solve the unexplained stuff he found along the way, but even his mighty knowledge ended up in the hole all physicists are trying to dig out today. He's only human folk, him and Mr Isaac were only humans.

If we need a large amount of negative energy to power the warp drive, surely we could use RUclips comments?
😂 That made my day
Unfortunately, the only thing you can get out of RUclips comments is cancer. The energy is literally useless.

Or you take feminists and SJWs on board the ship!
Just take butthurt Trump voters: infinitely dense & negative energy!
We need a *"It's never aliens!"* tshirt for SpaceTime :D
Is not logical to speak about when warp drive will be possible. Imagine living in the year 1870 without electricity, without lamps, without diesel engines, without planes and cars. Imagine someone says that 75 years from now (1945) humanity will have a small bomb who will destroy entire cities who create energy by smashing invisible tiny particles and we will use this against our enemies with a machine who fly.
You might be right since technological advancement is going exponential. It may be much sooner than we think...
@@SuperVorticon Or, tech advancement might prove to be finite and we get there, if ever, in millennia of research. We just dont know. Wanna know whats even cooler? The true unknowns. The physics, tech and methods that we havent yet discovered. Things that might be entirely different from anything we have discovered yet. Maybe even laws of physics that allow FTL without violating any existing laws. We simply dont know. Whats bad about it is that we wont get to see it. Even worse, the people that will live through those times will treat it as normal and they will go about their daily lives as casually as we do. I mean, you dont jump around your room everyday screaming "ZOOMG, I HAVE A COMPUTER", now, do you?!!!!
Look how fast humans have evolved technology wise from the 1900 to 2019 imagine what we will achieve in the next 120 years
Elom musk says that what we need first is a base on mars so faster transportation is something requiered
The problem is, some very USEFULL technologies are hindered like thorium MRS - with this type of reactor we would embrace cheap, clean and NEAR INFINITE energy (because thorium is 3-4 hundred times more abundant than uranium, 210 times more powerfull). It can't explode because no water inside.
Energy would be too cheap to measure slapping all fossil and renewables alone...

It means being born in or having some kind of personal or genetic relation to Africa in the nearest past.
You are totally missing the point.
1. I said FAULTY logic.
2. I said APPARENTLY.
The point of that post was not to be precise, or to make a true scientific statement based on any facts, but to answer in the same level of stupidity that mrpuffypants1 did.
why... is this thread?
I wait all week for these!

That’s the ship Spock came through time behind the Romulans..
Looks almost exactly like it.
It was refreshing to watch this video again. It's August 2023. I wonder what progress has been made since this video was published seven years ago.
This channel makes me feel like the largest idiot on Earth.
xXX5ceonwareXXx - bit.ly/1S5KqKs If I were actually in Mensa, I would have no reason to feel like an idiot.
Jwb52z What we know is little, and what we are ignorant of is immense....PS Laplace. This genius postulated black holes and gravitational collapse hundred years before even Einstein was born. So, Einstein too was an idiot before he learned about Laplace equations, Lorentz transformation or Maxwell's equations.
its not you, this channel has some retarded way of explaining science that is downright not understandable....
Don't worry there is always Ken Ham
There's always a bigger fish.
Woah that beard popped out of no where.
Beard had a warp drive I guess ;)
This is truly mind-blowing.
This is very interesting item. It makes one think about whether interstellar travel will ever be possible.
He's growing a beard, people, he's growing a beard!
Keep it.
these videos ARE enjoyed. Keep it up please!
Before anything! I love this channel!! Alcubierre is from Mexico ^^
Yinons (Lowest unit of negative mass) are everywhere according to the Heisenberg uncertainty principle and quantum fluctuations. It’s met with matter and vanishes instantly. If we just separate these particles, we could keep the universe balanced while getting both of what we need. At the same time though, this might just create really high frequency light.
What if we didn't try to make an FTL drive with an Alcubierre drive, but an STL one? Warping around at 0.1C would get us to other bodies in the solar system pretty quick. 0.5C and 9 years to Alpha Centauri.
There are much easier ways to get to 0.5c
Jacob Jensen Sure, but warping at STL speeds is easier than warping at FTL speeds.
Terra Novei
The problem is still present in creating the bubble and actually finding a safe and essential way to warp
KASASpace can you tell me what’s stl?
"Would've taken 40 years at only light speed"
Well, only partially true. From the point of view of a "stationary" observer, yes it would have.
But from the point of view of Han Solo, travelling at 1c, relativity dictates that local time "slows down" to practically nothing and distances are condensed, so travelling between any distance at 1 c means, from the traveller's perspective, that you arrive at the destination instantaneously, even if from the observer at the origin or destination it might have taken years or centuries.
A similar phenomenon: it's speculated that at the threshold of the event horizon of a black hole, where speeds are relativistic, an observer could see the rest of the history of the observable universe unfold in fast forward.
The first thing to go superluminal will probably be something very very small, like a single fundamental particle that uses the casimir effect to make the negative energy/negative mass needed. It may even happen in our life times.
This would be amazing!
This is unrelated to the video but, I had a thought about the apparent expansion of the universe. Bare in mind this is all just random baseless assumption. What if the entire universe isn't actually expanding, what if it's just the region of the universe we're in is expanding and there are other parts of the universe that are actually contracting. Much like how tectonic plates on the earth push together in one ridge and pull apart on another, only something similar is happening in the universe at a higher dimension.
+Yoges Singha As far as my understanding goes, your on the right track in terms of thinking about frames of reference and perception. From our current measurements it seems like the fabric of space-time is stretching. If it were an illusion or only localised to a certain region, I imagine the guys that can do maths well would have arrived at that conclusion. So until we know for sure I say that your lines of thinking should be encouraged - to be later proved/disproved. All too often someone who has read one article more than you will try and shut you down with a reiteration of an explanation they don't truly grasp themselves.
that's actually a theory it's part of the inflation theory's I think
+Yoges Singha The whole concept of space expanding is through the measurement of distant galaxies and how they are accelerating away from us. So the farther we see, the faster the universe seems to be expanding in relation to us.
Now since we can only see part of the universe I guess the rest could be contracting... Please correct me if I said anything wrong, not an astrophysicist!
+Mike Sloan maybe the region of expansion is larger than the observable universe?
Yeah exactly, it's a compelling thought.
why am i living in this time dang it
TheUCrafter I said the same thing! Lol why couldn't I live in another 500 years?! I think 500 years would be plenty of time to figure all this out! Just imagine what life will be like in 500 years! So far beyond what we can think of right now I bet!
Just be glad you weren't born in the 1,200's when religious zealotry about anti science made life hell.
It is not true, religion wasn't so much anti-science.
... Brze, it totally was. It was all about taking things on faith, belief, trust in church authorities, and NOT double-checking things against how reality works. Bruno was burnt at the stake for postulating that there might be intelligent life elsewhere. Galileo was censured by the church for espousing Copernican sun-at-center-of-solar-system theory.

@@zekethefreakztf9790 If we still even exist and skip the part of destroying each other with weapons of mass destruction. :)
Bob Lazar described a strikingly similar, overall, principle. In 1989. Irrespective of veracity it's an interesting anecdote that his sport model flying craft travels with the disc's bottom facing the destination, similar to the design shown here. It doesn't take much of a streeeeeeech to find potential correlation.
It is very interesting comparing these older videos to the current ones. He seems more hyper and is lacking a beard here, but still an awesome guy!
03:18 The meaning of life, the universe and everything.
"Element Zero is tricky, since there may be no such thing."
I want to hear more about what's required to build the warp highways.
*_The vital component of the light-speed warp drive is the counter-wound induction windings used to produce neutronic anti-particles by magnehelic repulsion transmitters, pulse-polarized using bi-directional episodic dipole diverters. Semi-acoustic vertically interspersed harmonic wave transducers are frequency modulated with capacitance inverters and phase- synchronized laminar condenser windings._*
when it comes to exotic propulsion, we should forget about newtonian physics
@Lady Fingerz i´m in a struggle to understand why this is a highlighted comment and what exactly it means
what would happen if you used an alcubier drive inside a black hole? i have never seen or heard anyone mention this, would it even work, would you be able to get out of the black hole or would you fold the black hole into itself?
Yeah homey, you thinking of two opposite phenomenon.
But hey, this solves one of the warp drive problems: its inability to turn off. When the bubble enters the gravity field of a massive star, it is no longer in flat spacetime, and tadam! it pops, and the ship inside is free to move and explore this new star system.
Now you only need to escape from the black hole gravity yayy
dude, in simple terms, that warp bubble around the drive is basically a black hole, expanding space behind and contracting whatever is in fromt of it
or, the black hole whould destroy the drive before it can do anything due to the gravity and radiation
Well.It wasn't easy..but decoding and deciphering formulas on how to bend space..&applied those principles to bend time
wow! this is mind bending. his hairstyle suddenly changed a few moments before the video ended.
That's what happens when you use warp drive
My only nit here is that whenever Physicists talk about the time it will take to develop Warp Technology, the time scale is 'centuries'. Given the limits of human thinking this is understandable, but it fails to take into account the possibility that we are evolving ourselves at a much faster rate. You can call it the singularity or whatever you want to call it, but the facts are we are moving to an inevitable integration of humanity and computers. AI, or integration, such a complex and rapid calculation thought process will allow us to find solutions in years rather than decades, and decades, rather than centuries.
Speed isn't the only barrier to space travel. When the day comes for 'humans' to venture across the galaxy, will the form we take even resemble humanity of today?
how about a mass effect relay from well mass effect
4:56 Lol, bypasses - If you have any complaints you can contact your nearest department on.. Alpha Centauri.
I don't think we should be thinking about Warp travel until we've figured out how to make Gellar Fields.
7:13 Holy shit you are a time traveller yourself. Look at that beard growing so quickly!
Would those travelling using a warp drive still be subject to time dilation?
+TorrenPtz Actually no. The patch of space inside the bubble maintains the same proper time as the point that it launched from. Clocks would tick at the same rate. So if your bubble traveled a 10 light year round trip at 10x the speed of light then it would feel like a 1 year journey for those inside the bubble and 1 year for those waiting at the origin.
+PBS Space Time thanks for the awesome info and video! It's awesome.
+PBS Space Time wow, thanks for the reply! Loving this series so much.
+PBS Space Time So why would a warp drive even be worth it? If I traveled the same distance with nearly light speed, I could reach my target in barely any time due to time dilation. Of course it would take a little over 10 years for observers at the point it was launched, but I guess the most important thing is to cut down traveling time for the travelers. However, if we can manipulate spacetime to make a warp drive we might also be able to produce artificial time dilation and speed up traveling even more.
+metalhead2508
Not to mention the fact that the reason we would send travelers is NOT so they can get a cool tour of the stars, it's to collect data, and for that, the only time that matters is Earth's time, and not the travelers'.
I got here cause I'm reading Marko Kloo's Frontlines series, in which they use alcubierre drives to travel the galaxy. Had no idea how to pronounce it.
They do exist. I travelled here here on one from the year 4230.
The future is beautiful.
negative mass matter layed down in your path? Mass-Relays, anyone?
If we had element zero all of this would be quite easy
@@jcanal0221 well like he said, if we get the mass/energy requirements low enough (which is feasible) we might not even need exotic matter (element zero) to create a warp field effect strong enough to make this possible.
Excuse me??, Miguel Alcubierre is not Spanish, he is Mexican, Thank you!
It did notate that in the video, even if he spoke the wrong words they recognized that and fixed it.
He is undermining the contributions of mexican scientist, no wonder Trump won the elections
A Sojourner Uneducated and illiterate? Just because they don't typically speak English doesn't make either of those true. They do have an education system in Mexico. Trump won those votes because we are afraid of people coming to this country and taking our McDonald's and cherry picking jobs.. For some reason..
A Sojourner you know nothing. Expose yourself to the world and stop marching to the beat of your propaganda king's. Nearly every word you typed came word for word from propagandists. Wake up and learn to think for yourself.
Its disrespectful its like me saying all white people are uneducated white trash racists who think the world evolves around them.
5:00 when he say space highways, my reaction HYPER LANES
Love the hitch hickers guide reference
if this could be done on a quantum level, could this be used to establish a communication system that works between galaxies?
My question is: Is there anything naturally occurring in space time that is detectable as an example of warp travel?
I double click reminded 5 times in a row and literally heard you say space time all 5 times lol
42!
More physicists!
Thank you
Dammit Jim I’m a Doctor not an Engineer! LMAO

Uses warp drive... " Hey, where's Earth?"
A more feasible form of space travel is explained in the book ‘Rules of Lore’ available on Amazon
Please do a show on the Hutchinson effect.
If that's solid Science, if, could whatever force is behind that prevent the warp drive from working.
If something like gravity, or electromagnetics is involved, perhaps the answer is in using it?
What's the difference between moving normally and moving as a consequence of the space around you moving?
+TheRealBileth
if you want to move normally, you have to apply force and gain some kinetic energy (you need much more and more when you approach the c)
in the second case, you don't actually physically move. the space warps around you and thus you change your position.
+TheRealBileth Moving normally means moving through the space-time fabric, through the higgs field. Because of its properties and resistance light speed is the maximum. At light speed time stops. That is also why photons are eternal.
TheRealBileth moving at or anywhere near the speed of light even 25% would require more energy then the whole planet currently produces in a year! The problem with ftl is the mass tje faster you go the heavier you become and the more energy you need to propell that growing mass. Warp drive is a way around this as there is no theorical limit to how fast space its self can move
Imagine moving a coin on a paper and now imagine moving paper under the coin. That's it.
"traveling at the real cosmic speed limit, one times the speed of light, would make for some pretty dull sci-fi."
The Expanse - "Hold my beer"
Yeah, except the Expanse turned into a dull soap opera itself.
Don't think I understand a lot of the stuff he said, but I like it :D
We have to work out how to shrink the mass being transported first, while also mapping the multi and micro verses. 👍
