"Or maybe pursuing this is all just a waste of time" -- No. Not a waste of time. A caveman decided to sharpen a stick once and that, through a chain of extremely unlikely and fortunate (or unfortunate) events, we got to discussing making warp drives in the first place. A caveman is already convinced we possess magic. And space travel, and the pursuit of it, has lead to so many innovations in just one human lifetime that our own parents have trouble keeping up. The future is built on the backs of all of these, often stupid, often fruitless pursuits. Be it an idiotic dean drive, or the first five hundred things a caveman sharpened before realizing he could stab things with it. We're getting there. Give us time.

[@michellebroyles5145]

Often cited why this doesn't work is the analogy of sitting in your car pushing on the dash to move forward. Let's use that analogy to explain in a basic way how this drive works and imagine you do it in space with no friction. Sitting in your car you somehow very quickly gain a little extra mass and can now hit hard on the dash with all your weight. Conservation of Mass says the car will move forward a bit, you'll push back a equal amount, but while your moving and the car is moving you can magically loose your extra mass. The back of the seat hits you with the extra mass you imparted into the car with the first hit on the dash and now you and the car move forward just a little bit more. You have shifted the Center of Mass, not defied it. Do this with a Piezoelectric stack with two unequal masses attached and the extra weight filling the stack is electrons and removing them. Do this tens of thousands of times a second and ever so slightly shifting The Center of Mass and creating a thrust impulse. Of course there are other things that are going on to increase/decrease the mass/energy of the system even more, by introducing second order higher energy harmonics into the moving Piezoelectric stacks, but the basic concept simply relies of foundational physics to work.

[@zackmorrison470]

I'm pretty sure "they" "officially" debunked the EM Drive at some point last year. It turned out that the "force" at work was the super weak electromagnetic interaction between the Earth's magnetic field and the electronics onboard the EM Drive. I would usually dig deep to link to the study which debunked it... but that's a lot of work for something that... doesn't. =) As for the Helical Drive, and the Alcubierre Drive, they may have more basis in reality. Obviously, the "oscillation" part of the Helical Drive is a bit silly, as is the requirement for "exotic matter" part of the Alcubierre Drive. However, particle accelerators don't NEED to be the size of the LHC; in fact, the Ion Drive is a type of particle accelerator. Also, we CAN "warp" spacetime with powerful laser light (although, something along those lines may be what is meant by the "exotic electromagnetic field generators," since light is just a wave in the electromagnetic spectrum.) We might also be able to "warp" spacetime with the mass "acquired" by particles accelerated to near light speed using a particle accelerator. I don't pretend to know the practical requirements of either form of "warping" spacetime in either of those cases, and it may well be that both are impractical at best, but it does seem to me that we have both observed the warping of spacetime with the gravitational wave observations which have been made, we have gotten pretty good at accelerating particles, and we might possibly be able to warp spacetime with electromagnetism in a way that becomes "practical" for "transportation." All that being said, 2020 has been a rough year, and I'd settle for anything that would "slow things down" so that "We" as a species could maybe recover our balance a bit and hopefully start making some forward momentum again. That too, seems pretty "far fetched." =/

[@barefootalien]

Sadly, the Alcubierre drive requires two different kinds of warping of spacetime. In front of the vessel, you need the normal kind of warping that "compresses" spacetime in front of it, just like gravity does. This we can do. Don't get me wrong, it's enormously non-trivial at those scales, but it is essentially an engineering problem, not a science problem. But at the _back_ of the spacecraft you need _negative_ warping of spacetime that _stretches_ it. This would require exotic energy or exotic matter with negative mass... and it would require a _lot_ of it. Putting aside that we have zero evidence that such exotic material exists (Dark Energy is subtly different and not useful for this purpose as far as we know), last I heard, with improved calculations and layout of the warp fields, we've got it down to the point where we "only" need approximately one Jupiter-mass of exotic matter to create the equivalent of Zephram Cochrane's prototype warp drive. There's also the small problem of the prediction that as one travels at supra-light speeds using the Alcubierre drive, one would accumulate insanely high-energy particles in the field that, upon deceleration to sub-light speeds, could potentially release enough energy to disrupt a planet. _Probably_ not a star, but still... So yeah... even if it ends up not violating the laws of physics (which it probably does), it requires obscene amounts of exotic energy/matter and may or may not completely obliterate your destination upon arrival. Fun! Or... something-something-handwave-primary-warp-coils-antimatter-reactor-warp-plasma-subspace-manifold-hrrmmrphrhm...

[@Aquascape_Dreaming]

@@barefootalien SOOOOOO interesting about the accumulative, destructive energy theory. I think I may have heard of it a little once before, but that truly is a major concern. As for stretching back spacetime behind a craft using the Alcubierre drive, I'm not sure if you saw the whole video, but Joe mentioned that some people (experts? No idea) believe that spacetime behind the craft would snap back to normal on its own without the need for the drive to use power to reverse the frontal effects... But who knows, it's all theoretical at best at this stage... 🤔

[@barefootalien]

@@Aquascape_Dreaming I did see that after I posted. And that the negative energy needed is down to just a few tons worth! I question how space is meant to "spring back" asymmetrically though, without the stretching field behind to cause it. I've also never heard a good explanation for what happens orthogonal to the direction of travel... Spacetime is essentially the stiffest "substance" known, which is why gravitational waves are so tiny in spite of the enormous energies they carry. I may very well be going too far with the "fabric" analogy, but... If it has any analog to shear strength at all, I'd think that would directly resist the motion of a "warp bubble". Either that or the field would have to be extremely "wide", enough for that shear strength to dissipate naturally.

[@barefootalien]

@Bret Richter Well, that's a common "pop-sci" explanation of aerodynamic lift, and there is _some_ truth to it... But if that was all there was to it, how would an airfoil fly upside down? Or how would a symmetrical airfoil produce any lift at all? How would a paper airplane fly? Anyway, I'm drifting off subject, heh, just some food for thought for ya. ;) (I can explain if you're interested.) But with regard to the subject at hand, the trouble is that air has basically zero shear strength. In the dimensions in which we have data on it (compression/tension specifically, as gravitational waves are longitudinal, like sound waves), spacetime is the stiffest thing we know of. I don't recall the exact numbers off the top of my head, but it's something like billions of times as stiff and unyielding as steel or any other material. So it seems likely that it's shear strength would be comparable and I've not seen anyone account for that in a presentation on an Alcubierre drive, that's all. In order for your air bubble analogy to work, the warp field would need to create a region of some medium _other_ than spacetime. Say... "Subspace" which is exactly how Star Trek gets around it. But the Alcubierre drive, as far as I'm aware, purports to simply create regions of compressed and expanded spacetime for and aft, leaving the interior spacetime unchanged. This, to my understanding, would not be like flying through air or like a bubble ascending in water, but more like trying to drag one region of steel through a steel plate. This is _possible_ of course; it's called stir welding and is used by ULA in their Delta rockets... But it takes orders of magnitude more power than flying through air. I'm just wondering if that is accounted for. I suppose I could read some of the papers on it...

I had two kinds of engine ideas. One was, admittedly, a version of Dead Drive with gyroscopes to "convert" linear force into perpendicular angular force. The other though uses miniature gravity waves bounced between two plates to form stronger waves. It relies on the idea that gravity waves act like photons in the sense that high frequency waves carry more energy than low frequency waves respectively. With this idea it then depends on matter of various kinds reacting with the waves to create a number of effects... which is where the idea passes WAY into the fictional. *Artificial gravity (NOT IMITATION GRAVITY, IT'S THE REAL STUFF! I DESPISE THINGS THAT JUST SPIN AROUND AND CLAIM THAT AS ARTIFICIAL GRAVITY!) *Possibly: artificial anti-gravity *Possibly: increased gravitational pull (from the matter in question, it weighs more with no additional mass) *Possibly: inverted waves (remember gravity waves basically go from 0 to infinite, whereas most waves go from -infinite to +infinite, so making inverted waves, - + could be useful)

You forgot the power requirements for the warp drive, it started out as turning the entire mass of the sun into pure energy, after some work they have that down to the mass of Jupiter. So there are multiple issues with it

[@grossindecency]

To be fair, Jupiter is a considerably smaller problem. But to an ant, all elephants are equally fucking huge.

[@Dragrath1]

Yeah the biggest issue however has to do with causality as the front of the warp bubble where the negative mass energy needs to go is separated from the craft itself by a causal event horizon. This means an external user needs to regularly provide pulses of negative mass energy in order for the warp bubble to actually work meaning a warp drive could only work with a preexisting warp infrastructure. That is the detail that very much limits the amount of applicability even if negative mass energy is real. Good for galactic mass transit not for exploring new places. >_>

@@cliffsmith23 That's where time dilation comes into play. Because time contracts at high velocities, so does space, which makes the distances and times involved smaller for you, who is travelling at these speeds. While on Earth, the distance for your ship is, let's say, 4LY, and the journey takes maybe 100 years, for your ship, space and time has contracted, flattened in your vector of motion. Which means that for you, the distance was only maybe .01LY and it took only a week or two. Both are correct - you experienced a week, Earth experienced a century. Relativity is whack.

The nagging question in my head is "what about brakes?" No friction in space means that we can't apply the same principles used in terrestrial vehicle design. No air, water, or road friction. If it takes so long for us to gain momentum, it will take us just as long to course correct or slow down which can be dangerous given the spontaneous nature of space. I guess I'm concerned with the reality that one glitch, oversight, or RST (rogue space thingy) can result in catastrophic mission failure. Any ideas? It seems like whatever we end up doing with gradual acceleration, we'll be handicapped in terms of manueverability. Maybe have backup chemical thrusters? Of course, that adds mass...

@@levilandes1719 Unfortunately alcubierre drives still cause causality issues. en.wikipedia.org/wiki/Alcubierre_drive#Causality_violation_and_semiclassical_instability Things like warp drives and wormholes that get around light speed by shrinking space or creating short cuts in space are called apparent FTL. The ship never moves through space faster than light but they still wind up at their destinations faster than light due to trickery with space compression. While apparent FTL gets around the speed of light limit from relativity, it does still cause causality issues though. Causality doesn't care how you got a ship from point A to point B faster than light, it doesn't care if you did it by moving through space at FTL speeds, or by taking a short cut, it just cares that you crossed a light year in less than a year. If an alcubierre ship can take you to Alpha Centauri in less than 4 years that still counts as apparent FTL, and since it can work two way you can use it to transport information back and forth and cause causality violations. en.wikipedia.org/wiki/Faster-than-light

[@39401JLB]

@@planetfall5056 I am not a physicist. I am also pretty sure that causality is not a thing. Einstein sort of doomed us; since there is no favored frame, and all orderings of observations represent a point of view which is valid -- there is no time. Everything in the history of the universe happened once, all at the same frozen instant -- what we see is just our particular perspective. This is a serious 'time' catastrophe. The problem is that while it seems like Einstein was wildly wrong, his predictions still keep passing every darned test we can devise. Enter the standard model of quantum mechanics -- it cannot explain time either. It works, and passes every darn test we can devise -- but it insists that there no so such thing as 'locality'. Modern forays into theoretical physics (trying to glue these two unruly beasts together) often try to find common ground in a 'timeless physics' -- where time, locality, causality, and other things which we have long assumed were fundamental -- all arise as emergent properties, made up of other 'more-fundamental' stuff. When all is said and done, causality might not be a fundamental at all. We might find that the Causality Ordering Principle doesn't hold. No guarantees, of course, and the regimes for doing fancy stuff might be well outside our reach for the next century or more... but the new physics could be quite exciting.

All this talk of, basically impossible, drives, brings me to an interesting thought - there's a rather nasty crisis point in our development as a species coming up. For some time now, it's been looking increasingly likely that there is no other intelligent life (quite probably no life at all) out there - certainly not close enough for us to be able to contact it. In a few years, this will become generally accepted, and, for the first time in our history, we will be facing the 'fact' that we are alone. At around the same time, I think it will also become a generally accepted 'fact' that we cannot get to anywhere outside our solar system (indeed, I suspect humans will never get beyond the Moon and Mars - and I have doubts we'll even manage sustainable colonies on Mars). So we are not only alone, but we are also trapped on Earth. And, interestingly, at about the same time, we will be facing the fact (no inverted commas this time) that we are destroying our Earth, quite possibly to the point where few, if any, of us will survive. So, not only are we alone, and can't get out, but we are also about to destroy the one place where we can survive. How will we cope with that ?
