- Can humanity build an Alcubierre warp drive?
Can we go faster than light?
Dr. Miguel Alcubierre was inspired by Star Trek the Next Generation's example of warp drive faster than light technology on the starship Enterprise. In 1994 he wrote a paper on how we could bend and warp space and time to travel faster than light within the rules of Einstein's general relativity. NASA has and is currently exploring if it is possible to bend the fabric of space and achieve hyper fast space travel with the Eagle Works lab. John Michael Godier spoke with Dr. Miguel Alcubierre on the feasibility of the Alcubierre warp drive and if there has been any developments within physics, including the use of dark matter or dark energy, and anti-gravity, to be able to make this possible.

This episode is a bit special. While Dr. Avi Loeb was the first guest we emailed and recorded with and the first episode of Event Horizon. Dr. Miguel Alcubierre was the second person we reached out to. This week also marks the unofficial one year anniversary of the creation of the show. So thank you all for watching, liking, and enjoying what we do. We appreciate your support.
Love the show and congrats on the first anniversary!
I could not be more happy for this show. And specially this episode. Congrats!!
Congratulations on one year! I've been with this channel from the beginning. I'll pick up one of your books one of these days as a show of support, who knows they might actually be good.
Wow it's been an entire year already? It sure doesn't seem like it. Time does fly when your having fun. I'm eagerly looking forward to the coming year to. Thanks for a great year John.
Cracking video buddy!!! 😊
Dr. Alcubierre deserves to be the namesake for real warp drives in the future. The mathematical tools for solving a "warp bubble" are as old as general relativity itself, yet here is the guy who did the math. And to think he was working the problem of gravitational waves long before LIGO's famous discovery of merging black holes.... TRUE VISIONARY SCIENTIST!!! Fantastic interview here, well done.
JMG, you and your channel are something truly special. Top-notch content first, everything else after. Keep on inspiring future generations!
There was a young lady named Bright, whose speed was much faster than light.
She set off one day, in a relative way, and arrived on the previous night.
I give you a Lemonorick award for that one :)
I agree 👌
This was used on a the 1986 Alphaville album Afternoons in Utopia.
The first song, "IAO" (which stands for International Aquarian Opera), begins with the word "night" and fades into the short IAO chorus (which itself is a lyric from the song "Afternoons in Utopia"). The album ends with the song "Lady Bright", a limerick about relativity, wherein the Lady Bright leaves one day and returns "the previous ...[night]", with the word "night" omitted. Thus the album loops back to its beginning. (quoted from Wikipedia)
@@glenmatthes8839 Just blew my mind listening to that albums beginning and end in sequence! 🤯🤯🤯
The other thing is that the album’s length should be infinite because in a way it literaly loops and never ends.
There is a 5k race in Atlanta (the Race Against Time) that starts at midnight before daylight saving’s time change... so that the runners have a negative time upon completing the race. It is very reminiscent of your poem.
You interviewed Alcubierre himself, thats amazing.
I was seeing the episode title in my feed and only noticed the words ... warp drive .. faster than light ... interview with Dr.Alcubierre. Wait ... John got an interview with fucking Alcubierre ?!
In warp drive we can't communicate and if you open any light you will not see any light because you're traveling faster then light. Looks impossible but good thoughts I respect his theory. Our body create infrared light we can detect it. Then, what happen to body. Does we suddenly stop glowing infrared light due to speed faster then light.

Shoaib Nature ur stupid lol u wouldn’t see anything outside but the light inside whatever ur vehicle is is still traveling at the speed of light+whatever speed the vehicle is traveling at so u would still see inside ur vehicle and light would still work normally inside it.
@@naturemc2 although relative to an outside observer you would be traveling faster than light inside the bubble you would be traveling much slower than light speed so this shouldn't be a problem.
This is the best interview on Warp travelling! I am lucky to have found it! The fact the you got Dr Miguel Alcubierre himself to talk about its really unique and priceless! Thank you!

The greatest achievements are from the edge of the practical and impractical, e.g. the history of flight (Wright Bros) or history of medicine, for example. This is the very beginning of a long journey to find ways to travel through space at the fastest speeds we know how.

"I came up with this idea myself, but it's probably not correct despite my own personal attachment to it."
-things preachers and politicians will never say
That's the difference between science and ideology for ya.
Science doesn't ask for the truth, but makes the best availeable approximation to reality.
Any scientific theory is essentially waiting to be made obsolete by a better model.
Proponents of ideologies or religions say what they say because they believe it to be the truth.
If they approached morality and philosophy with the same "this will be made obsolete eventually" mindset,
those very concepts would become meaningless.
If preachers and (honest) politicians assumed themselves to be wrong, they wouldn't say a word.
But like it or not, we need those words.
Everyone needs a basis to orient their moral compass by.
And so we need discourse about morality, on what is right and wrong, and how to make the world better.
A discourse you can't have without people holding sinsere convictions that they themselves will not doubt.
So you think that preachers came up with the idea themselves? You don’t put any weight to where that information came from?

It ain't gonna happen. MA took something from fiction (Star-Trek) & gave it a bit of real world math. However those initial calculations simply implied that it was basically impossible because it would require more energy than what was contained in the universe. There was nothing on how to 'warp' space itself, generate the warp bubble etc. Others have brought down the energy requirements to a now manageable degree but there is still nothing on how to make it practical from anyone as of yet.
@@jamesh8862 you never know. In 26 years it went from the entire universe to the size of jupiter. Who knows where the idea might be in another 26 years? 100 years ago we KNEW ours was the only galaxy ever, who knows what we'll know in another 100?

How did I miss this interview before? I love this interview. Science fiction that isn't nonsense ... I love it. Dyson spheres ... Fermi's Paradox -- all nonsense. This ... pure gold.
Alcubierre is one of the modern giants of theoretical physics! Congrats to the show!
wow you really got Alcubierre himself on the podcast!! Ohh M G!!!!
You mean oh JMG!!
But what he says about it really is not very good. Essentially he says youre sitting in a car and then you are generating a downhill so that you are always going downhill by rising space behind you and lowering it infront. NO explanation on how he would actually do that. So its useless.
@@janusha2253
Well that's because no-one has any idea on how we would do that practically, we don't even know if negative matter is a real thing or not.
@@jeffvader811
Exactly and he decided to skip the details. Just saying if its possible, then its possible. By creating a scenario in which its possible. Its like saying you could go really fast on your bike if you always had down hill. But you dont.
@@janusha2253
I'm not sure what you're complaining about. Dr. Alcubierre said that this is an entirely hypothetical propulsion system that relies on many assumptions, he never claimed that it was possible, in fact he said that he thought there was only a 1 in 10 chance that it would work.
Hearing this conversation is awesome, it must be what it was like to hear Einstein describe his theories that wouldn’t be proved out until well after his death, I doubt I’ll live long enough to see a working warp field or drive but it’s cool to be alive while these concepts are having their foundations laid.
I think there's a good chance we could have some kind of warp drive or something else, if you read scifi look up Peter F Hamilton's Night's Dawn trilogy, but anyway I'm guessing we'll have some kind faster than light drive within 100 years, hopefully we'll have fusion power well before that!
@@segura2112 sci fi is great and a lot of ideas come directly from its pages. But if you want to here someone talk seriously about warping space then check out Dr Richard Obousy, who's work builds on Dr alcubierres

If we were to ever figure out a practical means of traveling faster than the speed of light (at least in effect), it’s almost impossible to overstate how reality altering that technological development would be. It would be a game changer without comparison, perhaps with the exception of the ability to control fire.
So his first scientific paper got a concept named after him --- badass!
ontoverse as well as the first superluminal ship.
@@over7532 There some other ideas of Superluminal ships. Wormholes is likely the most popular one. At least for those are going by actual science. But there are a ton of other ideas out there. One often more wacky then the other. Really popular idea is to use quantum tunnelling or similar effect. Though these ideas from as far as I can tell are often build on misconceptions of quantum physics.
I am guessing that if one would make a stargate system with a artificial wormhole that the each end would be called Einstein and Rosen. After Einstein-Rosen Bridge that is the formal name for a wormhole. ;)
@@Cythil I'm of the camp that hopes for Faster Than Light Communication myself, it might be more practical as far as it's energy need go, and more achievable in the near term if we perhaps could find a way to use Quantum Entanglement or a detectable / Re-create able faster than light form of energy perhaps ... or even a very small wormhole conceivably where you make it just big enough to fire a laser threw it to communicate.
I'd be too paranoid, personally, over the possibly implications if a FTL drive failed, IE a Warp Drive shutting down mid trip could end with your ship exploding into a burst of high energy radiation when it 's found to suddenly be violating the speed of light, so to speak, by the universe around it
@@UNSCPILOT I am more sceptical. I think much of that come to people misunderstanding how quantum entanglement works. And why is not a good way to communicate new information faster then light.
Let me make a analogy to explain. Two entangled particles are like having one ball and two urns. You drop the ball in one of the urns without looking. Then separate the urns from each other. You then look in one of the urns. After looking in that urn you know instantly if the other urn contain ball or not as there was just one ball between the two urns. Even if they separated 2 light years away from each other. So no real magic behind it.
(Well there is one bit of magic. And that is that until you look the urns actually act as if both contained a boll and not at the same time. Which means you can do all manner of things with these urns in super position until you look. Note that any method that lets you determine which urn contains the ball will make the waveform collapse. So weighing the urns would not help as a way to get around it. That is why is so hard to keep super position. There so many way information could leak out you could say.)
Every time I hear about the Alcubierre drive, I have to chuckle at myself. I was a pretty imaginative kid growing up, and I spent a lot of time thinking about science fiction (and reading a lot of it, too) and thought of something along similar lines to the Alcubierre drive. My thinking was like this: If you get in a little wagon at the top of a hill, a small push will accelerate you toward the bottom. If you could somehow "move" the hill, so you never reach the bottom, you could reach incredible speeds. What if this were applied to space travel? With a field or area behind the craft pushing it forward, and the opposite in front, pulling the craft along? Some way to create a gravitational effect in front, and an... anti-gravitational effect behind, warping the fabric of space to create a perpetual "hill" to push craft along at speeds faster than light. Of course, there'd have to be a plateau between these effects to prevent the craft from being torn apart by gravitational strain
Maybe if I had been older, and thought it was something that could exist outside of my imagination, I might have proposed it and then it'd be my name associated with perhaps our best shot at FTL.
Merely "moving the hill" does not mean that you wouldn't flatten out - I know what you meant but poor choice of words. Secondly, even if you "continually "elongated" the slope hill, at some point your speed would plateau - even in a near-zero vacuum - you would need a "differential" somewhere in order to obtain more speed. If both the contraction and the pushing are equal, then your speed will neither increase or decrease. In my opinion, this was not about traveling faster than light, it was about the energy required to create enough of a gravity field to warp space - if you can "fold space" space, then does it matter how fast you're going...not in my opinion. Now, if you need to travel a few hundred million miles to access said "fold" in said "space", then you may want to consider beefing up the speed of your craft!
DERRICK LANDERS Why not “Fold” over and over again?
I found this channel because of Ian Douglas’s “star carrier” series. Dr. Alcubierre was something of a god figure there and this man did not disappoint!

The idea of warping space-time in a useful way to achieve FTL travel, didn't begin with him...*or* Star Trek.
The latter merely popularized it.

Not yet. We need to build this thing and test it successfully first. Our limit here is the insane amounts of energy required for such a thing.
Except it's not gonna actually work in the real universe.

Delightful conversation! I was looking forward to this episode and it didn't disappoint.
The whole team deserves praises for all the work you put into this fantastic show. Thank you!
Great interview. Alcibierre should think about doing more "public" work.
@The Jim Reaper™ I suspect his work centers around finding and proving a given thing...............not engineering it. Spending some time as A science communicator will not hurt. Approaching 100K views in less than a week. Clearly people have interest in the topic and this is not some dumbed down content geared for click baiting idiots with the attention span of a fly on crack like 85% of youtube making it all the more impressive.
@The Jim Reaper™ a joke? A JOKE? AAAA JOOOOOOOOKE?!?!?!?! NOOOOOOOOOOOOOOOOOOOOOOOO
Frankly shocking that no one tried to do the math of a warp drive before Dr. Alcubierre.
Been catching up on this show. I like the different guests and how they differ in their ways of approaching speculation.
Didn't even start watching, I've already liked it !! 1 hour !! Oh wow !!
Man this channel is i would say pure gold but that's not enough scarce and valuable to represent it. So this channel is pure anti-matter! I'm deeply impressed by the quality of the hosts you are able to reach :o Also you keep the content very interesting, (even for initiated people and that's rare on youtube), by asking good questions and taking the time to let them answer it fully with this format of videos. Found you thanks to Isaac Arthur and your first featuring with him on your other channel quite some time ago now and i just wanted to express how grateful i am to both of you for the amazing work you guys are doing. And i also want to thanks the great minds you have the chance to interview for giving us common mortals some of their precious time and for their incredible scientifique work too of course. You guys are freaking inspirations for a lot of us so thank you for that!
Thanks! Many more shows to come!
The lack of issues with wormholes is one reason I believe there's something massive we're not seeing that's a huge deal breaker about them. I think the warp drive is more likely because we can actually see the issues with it, it isn't a "too good to be true" situation, it;s a "we have no idea how to fix these problems to make it happen but if we could it would at least work decently." There are compromises, there are needed modifications to make it doable, and that is the sign of a truly doable idea. Things that look too good to be true typically end up being more trouble than just doing it the hard way.
I thought keeping a wormhole from collapsing almost instantly required negative energy. I need to double check. But I think that's at least one of the other major problems with it.
That nintety-second intro is STELLAR!!!!
This video is like the fine print between the lines. Finally, properly summarized.
REALLY COOL STARSHIP at the beginning !!
Internet gold right here. I never learned so much about how a warp drive is possible yet far away.

It really is amazing. Love Mark Rademaker's work.
Just discovered your channel. Great content! Subbed for sure.
Dr. Alcubierre really poked a lot of “holes” in his own model.
I'd say he clarified a few of the "warped" views some of the people working on this subject tend to develop as a result of the "lensing effect" caused by incomplete math's.
I mean that is the job of a scientist to prove and to disprove because they are the seekers of truth not the seekers of glory.
It's full of bubbles as it is.
Just because you brought Dr. Alcubierre, I will subscribe! Thank you and job well done with your video.
Me too!

Has anyone considered that traveling superluminally is possible. It is like traveling in the future/past (sort of), just not along a vector that lets you change the past or get lotto numbers from the future. To do so, you'll need to figure out how to create antigravity.
For people following the UAP/UFO phenomenon Dr. Alcubierre is extremely relevant right now.
The reason you can't travel backwards in time is bc the past and the future are human conceptions based on our ability to remember and from memory use our cognitive skills to predict events to come. Time evolves at different rates only, it doesn't actually have a direction. The direction of time is something we invented in order to better organize events. Thermodynamics also prevents this, bc going backwards would violate those same laws that prevent a broken glass from spontaneously reforming.
Phenomenal as always John!
Super interesting conversation! I subscribed. Keep up the great work!
The equations for relativistic velocity actually would allow one to travel faster than light. But traveling AT light speed is not possible for any massive object, no matter how small. It is the speed of light that could never be achieved. A specific equation indicating that is called the Lorenz Transform (of velocities) or the Relativistic Transform. Conventional transform of speeds basically consists of addition and subtraction of objects moving with respect to one another. There is of course a trick to travel faster than the speed of light. One would have to start off while moving faster than light, that is to begin with. Theoretically, there are particles called tachyons than travel faster than light speed. They might have come into existence first, during the Big Bang.
I know one thing regarding this topic. If we ever create a warp drive that takes us from point A to point B in normal spacetime faster than a light beam then all the relativistic equations that contain the speed of light (c) are wrong. This is because these relativistic equations need to use the fastest speed at which information can be transmitted. If a faster than light warp drive were possible, that would mean that you would be able to transmit information faster than light from point A to point B in regular spacetime.
Now, you might say that in a warp drive faster than light speed is not achieved by moving through spacetime, but by having spacetime itself expand faster than light. But this does not remove the problem I explained. If you can be in a spacetime bubble that moves faster than light and then exit this bubble and reemerge into regular slower than light spacetime, you would be able to use this mechanism to transmit information faster than light from point A and point B in regular slower than light spacetime.
Imagine point A and point B in regular slower than light spacetime and then putting a warp drive in between these two points. So as far as points A and B are concerned they don't know about this faster than light warp drive between them. All point B knows is that it received information from point A faster than light. And once this happens then the thought experiments that Einstein used to arrive at the relativistic equations can no longer be correct since these thought experiments assume that point B in regular spacetime cannot receive information from point A in regular spacetime faster than light.
The only way to circumvent this problem with a warp drive is by saying that a warp drive doesn't just alter the speed of space, it also alters the rate of time flow. So that when you leave point A and arrive at point B using a warp drive, it will be faster than light relative to your onboard time, but to observers outside your ship the time you took to arrive at point B would still be more than for a beam of light.
45:00 blew my mind. Imagine leaving for a crazy mission and completing it in 15 earth minutes lmao
56:00 They are basically talking about Stargates now.
If you're talkin Stargates wouldn't there be 2 Stargates sandwiching you in the center
More like about space trains.
I am currently traveling faster than light. Warp speed through many star systems. Well, in virtual reality playing No man's sky. This channel is the perfect companion to listen to while exploring the virtual universe:)
54:05. Yes Lol. It's the same speed limit as everything else. 186282 miles per second. !!!.
55:25 Actually the horizon problem is not really even a problem at subluminal speeds. It's only when you try to go faster than the speed of light.
1:01:50. While it is tempting to call a black hole. A hole in space. You are correct. There are no holes in space. Nor do we know how to create one. If a black hole is not by definition an actual hole in space. I also agree that your version of the Warp drive will not exist. But lesser version certainly may. Moving at much slower subluminal velocities. 20% of C and under. With no need of a track. The warp bubble could be generated from within. And it could slow down. Also that amount of internal radiation could be contained. And while that limits the distance that could possibly be traveled. The time dilation would allow the ship to travel for thousands of years at that speed. While only tens of years would pass within the Warp Field. However to get to at least our light horizon. It still take millions of years. Which could still be possible with cryonics. Or Chemical Glass Transition specifically. which is a handy technology that could still work even at 10% of 1% of C. Because of the length it can sustain stasis. Also if it becomes possible to reduce the mass within the warp field. Both safety and efficiency would increase drastically. These options DO seem far more possible and therefore likely. But to be honest. It seems like the best way to get anywhere. Is to get there without moving. Or some form of instantaneous travel. Seems more likely.
1:04:00. Sorry to put you and your theory on blast. I am not a hater. I am a realist. And while there are many aspects of your theory that make it impossible. I feel like it is an important step in the right direction. So thank you for that sir.
1:03:03. Great video. If you've read this whole thing I appreciate that you appreciate your subscribers and their comments.
15:50. Speaking of misunderstanding. Quick side note Dr Alcubierre. While space can be distorted. When this happens you cannot really describe this as stretching. In the same way if I crinkle up or fold a piece of cloth. I am distorting it shape. But I am not stretching it. If I want the cloth to be bigger. I have to add cloth. Now you might ask where is cloth coming from In this two-dimensional analogy of a 3 dimensional function?. And the answer is Everything that exists!. And even everything that doesn't. As we know matter is energy. And eventually all of that matter will return to being energy. When this happens new space is created. And the universe expands. So entropy is the cause of the expansion of the universe. Not stretching. The expansion of space is due to the accumulation of space. Not the stretching of it. Gravitational fields themselves are a compression of space. Which is a distortion. But not a stretching of Space. And well I too am guilty of using a two dimensional description to describe a three-dimensional function. It is this original description given by Einstein. That leaves the impression of a stretching action. When the reality is inverst or opposite. It is Spatial density. That can be used to describe gravitational field strength. Not the metaphorical gravitational well. That best describes the distortion of Space we call Gravity. So not stretching. Compressing!. Hope that was helpful.
17:15 Also if there is no limit to the speed at which space can expand or contract as you say. Then why do gravitational waves only move at the speed of light. Therefore you're warp field would only move at the speed of light as well. However the rate at which new space is accumulated can be more surface area then light can travel in the same amount of time it takes to create that additional space. Allowing space to expand faster than light. But one day the universe will run out of fuel. And come to a stop. And with no moving space. You cannot have time. So with the last bits of matter in the universe so to go the last bits of time. At which point the universe will reach maximum inflation with perfect spatial uniformity. And prepared for recompression. But that's a different story. I hope also this piece of information was helpful for you.
22:25. Literally. That is exactly how it can be and should be described. You were correcting his previous assessment and or terminology. But turns out you were totally wrong on both counts. It is 100% best described as "Spatial Density" !. What you should have corrected him on. Was the order and or direction. He said a lower "Spatial Density" in the front. And a greater "Spatial Density" in back. When obviously it's greater "Spatial Density" in the front. And lower "Spatial Density" in the back. But what ev.
24:20. As far as I know negative energy is created every day in the lab. We obviously can't make very much of it. Not even a fraction of a fraction of what is needed. But as far as I know negative energy has been proven to exist.
30:20. You think negative mass is hard to do. Try negative motion.
31:00. You mean the way you understand it.
33:30 Maybe they were stable. But like antimatter reacted with all available substances. And know all that's left is normally charged baryonic matter.
33:55. Yes.! In fact that's where most of Space comes from. It was the entropytal reaction between matter and antimatter during the initial expansion of the universe. That produced most of the space. And therefore most of the expansion of the universe.
34:28. We are an imbalance in the matter to anti-matter ratio. Indeed we are left overs. But I think the real question is. Was this intentional.?
35:30. It wouldn't be anti-gravity. It would be anti-gravitational. Just saying.
40:11. I mean I know it's your theory man. But that's not how it would work in real life. Sorry man.
40:25. It's called the Doppler effect shift. 40:32. You got it.
41:10. An obvious solution to those problems would be to reduce the possibility of any interaction. By reducing the mass within the warp field. Essentially turning the ship into a WIMP. Or a "Weekly Interacting Massive Particle". Like a Neutrino. Which could be done with a negative energy field. Much like the warp field. Perhaps doing it intrinsically. It would not only increase efficiency. But safety as well. Everything would just pass right through it. !!
47:33. The thing about Stephen Hawking's test. Is that it depends the future humans going to the past. But perhaps this is the first go-round. And we just haven't gotten there yet. Once we do. I guess at that point maybe in a parallel reality. Someone would show up to the party. But certainly I don't see how anyone could show up before time travel is invented. Mechanically speaking. that's as far back as you should be able to travel back in time. If you are at all able to do so. Which I don't think it's possible. Considering the function of time. In a traditional mechanical sense that is.
49:05. Well everything is traveling through time. And in that sense everything is a time machine. However even further time dilation occurs with increased velocity. So even if you weren't traveling back in time. You would still be traveling slower in time. And could still be considered a time traveler. Same thing if you went into orbit around a black hole. However. If you attempt to travel faster than the speed of light. You would in fact start moving backward in time. And that would absolutely make you a time traveler. So literally in every sense of the word. A time traveler is exactly what you would be. In every way that you could be. And by your own admission as soon as that reverse time dilation occurred. It would immediately be destroyed. Negating any faster-than-light travel. So yeah that statement is definitely wrong. I don't feel like you've given this enough thought man.
49:45. Because the warp field bubble could not travel faster than the speed of light. If it attempted to do so. It would be subject to the same effects. Regardless of the flow of time within the warp field. It would still produce feedback and it would still blow up. It would absolutely be a manipulation of time.
If the headline asks a question the answer is nearly always, no.
It’s nice to dream though.
The Betteridge's law of headlines.
I have headlines from computer magizens decades ago that claimed solid state and virtual memory would never work. In reference to the video it should be, at current technology, no; in a few more tech leaps, yes.
Alamyst2011
The thing is if you’re harnessing the power of a black hole or even just a sun then, once in a while an accident will destroy a solar system or worse. So to test such tech you would want to take it to a safe distance, and that would take decades.
@@parajacks4 I agree. My only point was that now the tech is not there. Ask the question again in 50 years.
Wow. That was fabulous. Thank you both.
What an amazing conversation. Subbed ♥️🙌🏻
Always thought Dr. Alcubierre was a mythological character :) Thanks for having him in your show!
You are most welcome!
My hero, The Science Troll... :D
Dr. Alcubierre: Ima just leave this idea for warp drive here. K. Thx. Bye.
Plenty of space to build out in space. Can you build a generator. Larger be make star gate i have videos on chain wormholes
I love this Alcubierre dude.
Really enjoyed this episode, one legend being interviewed by another legend :-)
I've been waiting for this a long time. Let it roll!
Great! Enjoy!
@@EventHorizonShow the most wonderful part of even having the knowledge that this theory exists, is that human history shows us that; as far as mechanics and engineering of our physical world goes, whether it is 50 years or 500 years, if we can imagine it, we can create it .
From DaVinci's theoretical flying machines, to cellular technology, facetime technology....whatever it may be, we eventually create it.
So, Alcubierre created a theoretical paper that may have a much greater impact on our future than he even is aware of.
Gene Rodenberry probably never dreamed that his Starfleet computers were in his near future, and were actually not imaginative enough to compare to what we now have.
The Alcubierre shows a model of theoretical working....it's not impossible to imagine this now.
It's one of the least hyped piece of theoretical physics out there, but it's actually profoundly interesting.
I imagine that his current studies are the closest thing for now to understanding a theoretical "fuel" for this dream, even if that's not his intention.
Sorry, I get excited about this. My science education led me into a satisfying life of tattoo art, so I admire these great minds.
From the description of the "Interstelar Highway System", it seems like each "negative energy generators" on the way must be completely automated; activated at regular intervals regardless if the Highway is "used" or not. Then it would also be the case that standarized automated "Shielded Pods" (with radiation protection on the "front") will go into the Highway constantly & exclusively.
. Any cargo or ship that enters to it from "behind" & attaches to it while it is stationary near the begining of the Highway (waiting for the next scheduled activation) will be mass_measured by the Pod (simply by moving a bit), then ejecting an equivalent ammount [ so the effective mass moved by the Highway System is always the same, avoiding the need to "update" the generators ahead with a different requirement, something that would had to happen at the speed of light].
[IF necesary] -> You could send a "data package" in a pendrive_like solid object to the other side (with the instructions for a "special configuration", like your ship); so it reaches the end of the Highway faster than light (where it can send a laser signal at speed on the opposite direction); posibly reducing the time needed for this update by almost half [ I will roll the dice and say it takes 42% less time than if you just send the signal from the start ].
About the return trip: Assuming two "Highway Lanes" can not be simply constructed next to each others (interference), then the "start" of one & the "end" of the other would be placed [in the same solar system] at the L4 & L5 Lagrange Points of a large circular orbit (with its plane perpendicular to the "line" made by the Highways); this would require the creation of an artificial planet massive enough to provide passive gravitational estabilization.
The "negative energy generators" along the Highway would have to "emulate" this orbit by using their ~powersource~ to constantly change their direction bit by bit [not a problem considering the energy levels they must be able to produce in the fraction of a second a pod/ship passes].
-> There should be a constantly shining powerfull laser for the precise calibration/alingment of the Highway (that would also be usefull to detect any form of matter "getting in the way" of the Highway because of the scattering it will create), allowing the most nearby drones [spaced regulary every few light_hours] to use even more potent lasers to "clean" the path by vaporizing & pushing gas/dust.
Give me a break
Holy shit, I was like... this will be interesting. Then I hear "Our guest, Dr. Alcubierre".... I'M SORRY WAT?
Yeah, light speed or even 10-20 times light speed is not enough. Our galaxy alone is 100,000 light years across, we would be able to explore our closest star systems, but no further. On the other hand, our current science based on Einstein's theory could be completely wrong, or missing parts crucial to traveling the universe.
Half the things we send to mars doesnt even make it, i have a hard time beliving that we would get to the right planet or what ever even tho we could travel extremly fast
What about a version of base 8 math?
The clue...? ‘Spooky science. Certain atoms that once shared electrons, when one is affected, the other reacts even though light years apart. I don’t know (wish I did) but believe that there are things we don’t know or understand- and Einstein had a partial understanding- but not complete to the marvels of the universe. CERN allowed us to see quarks, and spooky science, so I feel this is our next generation’s of scientists clues to build and expand on...

What an absolutely fascinating and thorough discussion! Thanks :-)
Thanks for watching!
WOW what you say about time travel is what i have been saying. to go back in time would create a loop or tear in the fabric of space. also that you can travel forward in time but this is more like time dilation. Awesome, i consider time like a sheet of paper that moves forward, you cannot go behind the sheet but you can make bubbles in that sheet in which time slows down or speeds up depending on the gravity in that bubble or around it.
"I just wrote the paper and then did nothing else and just watched what other people said about it." Sound like the career of Gene Roddenberry.
This is one of the best science-related interviews I've ever listened to. You have a unique talent to get someone talking on hypothetical subjects without verging into the sensationalism that plagues 99% of popular science content. Keep it up!
Never been to this channel but I recognized Godiers voice immediately.
Glad you found us. This is his second, long format channel.
@@EventHorizonShow yeah its pretty interesting. You need a long format to parse a lot of these topics out properly.
Negative energy - anti-matter or dark energy and add a energy plasma shield. Excellent episode of EH with Dr. Alcubierre - John!
15:38 The image reminds me of Arthur Clarke's Superiority story: "It seems very difficult to explain the operation of the Field to the layman. According to the technical description, it "produces an exponential condition of space, so that a finite distance in normal, linear space may become infinite in pseudo-space." Norden gave an analogy which some of us found useful. It was as if one took a flat disk of rubber - representing a region of normal space - and then pulled its center out to infinity. The circumference of the disk would be unaltered - but its "diameter" would be infinite. That was the sort of thing the generator of the Field did to the space around it.
As an example, suppose that a ship carrying the generator was surrounded by a ring of hostile machines. If it switched on the Field, each of the enemy ships would think that it - and the ships on the far side of the circle - had suddenly receded into nothingness. Yet the circumference of the circle would be the same as before: only the journey to the center would be of infinite duration, for as one proceeded, distances would appear to become greater and greater as the "scale" of space altered."
Those atomic hot wings I ate last night, certainly went through me faster than the speed of light.
Given the length of the human intestinal tract that might give you time to get to the bathroom.

Thank you. Very interesting to hear the creator of an idea disect his idea for public consumption.
SUPER LIKE! 👍 Thank you for this.
Interesting....... Thank you for sharing this wonderful scientific video. Learning about our Universe is so mind boggling !
this was fascinating!
Nice video. The interviewer asked good questions.
At the risk of being a party-pooper, let me mention some other very severe problems with the warp drive idea. (And please read my entire comment.) Although the laws of quantum field theory predict the existence of negative energy, they also impose severe restrictions on what you can do with it. This has been the subject of many researchers over the past 30 years. Some quick examples: Several decades ago, Pfenning and Ford (Tufts University) showed that, for a 100 meter size warp bubble (about the size needed to contain a ship), the amount of negative energy you would need would be minus many, many times the amount of stars in the visible universe. Furthermore, this negative energy would have to be concentrated in a thin layer that could be no larger than about one Planck thick (about 10 to the minus 33 centimeters). (The Dutch physicist Chris van den Brocek has shown that you can narrow that down to (only) about the mass of the sun, but that also has some similar problems.) Matt Visser (University of Wellington) and his colleagues have shown that you need negative energy even for arbitrarily low sublight speeds for this kind of bubble. The amount of negative energy you would need for a superluminal subway, compared to a warp drive is far, far worse. Wormholes have also some of the same kinds of restrictions as the warp drive, e.g., distribution requirements on the negative energy. (Side comment: a negative mass particle will actually fall towards a positive mass planet. This comes from the fact that, although the mass of the particle is negative, and therefore is directed upward, the force and the acceleration are oppositely directed.)
None of my comments are meant to be aimed against Prof. Alcubierre directly, nor are they meant in any way to be personal attacks on him or anyone else. I hope that anyone who responds to my comments will accord me the same courtesy. Many people have not done so in the past in similar discussions on other sites.
Finally, let me say that I would very much like to travel faster than light in one way or another, like most people watching this video. I hate to think that we will always be stuck on this planet, and can never travel to the stars. I sincerely hope that there is another way.
i just love this channel
Thanks this is one of my favourite chanel
Holy shit more than an hour. Thank you very much for this.
You’re bleeping welcome!
These longer ones are the best. I hope there's some good over the edge clips.
Holy shit indeed... time to make some hot chocolate....
Can we travel faster than light?
Very probably, but I suspect we need to stop thinking in terms of fuel and thrust and start thinking in terms of electromagnetic polarity and field manipulation.
I think that given the right understanding, intergalactic travel would be as trivial as intercontinental flights are today.
But we're a way off that at the moment.
centuries off.
Wow. This episode was eye opening and a bit unsettling. It's fascinating, listening to Dr Alcubierre and the host JMG. But wow, to think of what is coming in scientific discoveries and developments really is inspiring and a bit scary (not really, more thrilling than anything).
Regardless of whether we can (yet) there are those out there who can. They told us that 'thought in free space' typically travels around four million times the speed of light. It doesn't take much metaphysical study to realise that even around Earth there are other higher vibratory planes, wrongly called other dimensions, or other universes, where even light (there) travels faster than light (here). The natural energetic vibrations increase by a factor of 49 from plane to plane, so for example light on plane three travels around 2,401 times faster than it does on this basic plane. By the time we get to 'level seven' it is 49^6, which is over 13.84 billion times faster. It is on these higher vibratory planes that many non-Terrestrials travel the great distances. This concept I suppose is where the idea of hyperspace comes from? But one has to remember 'It is all physical', in fact in higher vibrations it is far more real than we are ...
Ok, I found the intro track. It is Miguel Johnson - Gaia Beyond. My bad
20:00+ The things that guys do when Procrastinating from working on their PhD dissertations, lol... :)
Great point
Amazing content!
There is a catch to this particular method. Negative energy would be gravitationally repulsive, that is it would rise instead of fall. However, what would it do in an Equivalence Principle experiment? That is, in an accelerating rocket. The rocket would not need to be "touching" the negative energy. If it is part of a system of objects and energies in a local space, the rocket could surround it completely. Then it would fall to the tail of the accelerating rocket same as everything else in the local system.
This would allow detection of the difference between a gravitational field and acceleration, violating the Equivalence Principle. Since it is an assumption of General Relativity, the theory would be invalidated, along with the equations for the Alcubierre drive. Perhaps another theory could be constructed which would allow this, but General Relativity is not it.
Rather than complain that I am the bearer of bad news, focus on doing the things we can do. We can go to nearby stars at significant fractions of light speed. We will learn to handle energy levels that could easily destroy a planet without doing so. In other words, we'd learn to be a trustworthy species, which we are not anywhere close to now, or die trying. A worthy goal. If we pass, we can worry about negative energy. Worrying about it first will only delay interstellar trips, with false hope something better is just around the corner. Star Trek may be the biggest obstacle to interstellar travel, because it sets unrealistic expectations.
So happy this is over 30 minutes I miss long uploads
Wow, you guys are absolutely amazing me with the guests
There is a reason why......,
The ships in the TV show " star terk" ?
Are shown " stretching," in the direction of travel.
Also, a good reason why ,
One should not to start said drive, until you reach the very edge of the solar system.
A very good reason.
So its basically distorting gravity. Like your falling in the direction you point the distortion. Very interesting!
Spectacular interview I really enjoyed it. As for the LeBaron you just need to add some warp nacelles to it and a deflector dish and you could travel at warp speed while listening to Star Man on eight track. 😁 Thanks for the episode!
