Introducing the Warpship 361

astroengine writes "Dr. Richard Obousy, a guy who has put modern science into the warp drive, has designed his very own warpship. Now, for the first time, he's shared it with the world. It might not be the sleek Starship Enterprise, but its structure has been optimized to harness local 'dark energy,' generating a warp bubble so faster-than-light velocities are possible." Now, the only question is: will the ship achieve faster-than-light travel ... or will the company hit those speeds once it has enough money from investors?

    How about we figure out how to warp time first and then figure out a ship to utilize that science for the sake of travel?

    The physics behind the warpship is purely theoretical, however. 'Dark energy' needs to be understood and harnessed, plus vast amounts of energy needs to be generated, meaning the warpship is a technology that could only be conceived in the far future. That said, Dr. Obousy's warpship design uses our current knowledge of spacetime and superstring theory to arrive at this futuristic concept.

    Translation: We have a theory based on a lack of theory.

      I have a warpship, and the design doesn't need to rely on

      our current knowledge of spacetime and superstring theory to arrive at this futuristic concept

      Instead, the design relies upon our future knowledge of spacetime and superstring[1] theory. That's the nice thing about it... warping space time in a bubble around the ship can result not only in FTL travel, but also time travel. So why should I constrain myself to the currently available theory?

      [1] Also a little bit of sillystring theory, but it gets messy at that point, so I won't go into details.

      I actually know this guy (he was a grad student where/when I was an undergrad). He's not crazy and at least mostly not a crank (I only say mostly because it's never possible to judge that sort of thing perfectly). The article, like most crappy science journalism, doesn't really go into details, so I'll try to recall for you all the contents of a talk I heard him give to a small group once.

      The basic idea, which you can probably get from the article, is to construct an Alcubierre bubble or Alcubierre warp drive. The Alcubierre bubble is a genuine solution to the Einstein field equations of general relativity; it is a spacetime metric which could conceivably exist. Part of the trouble with making one is that you (at least naively) need exotic matter of some sort (tachyons, negative mass, etc) in order to do it, but we obviously don't know of any exotic matter at all presently. What you really want is to make spacetime contract ahead of you and expand behind you. Well, we do know of something that makes spacetime expand: dark energy! So, if we had some way of manipulating the local strength of dark energy, then we could make spacetime expand behind us faster than normal and expand in front of us slower than normal (or maybe contract, I can't remember exactly how far that side of things went). There are apparently some suggestive features of superstring theory that indicate that we might be able to use the Casimir effect and/or cause an expansion or contraction of string theory's predicted extra compact dimensions to affect the local strength of dark energy. Here's another failure in memory, as I remember that the Casimir effect and extra dimensions were both involved, but don't remember which one was supposed to affect the other and which was supposed to affect dark energy. This is about all I can remember. My apologies that it is not more complete.

      Now, all this is of course very speculative. It depends on some things being true which might or might not be true. The existence of dark energy is at least strongly indicated by astrophysical data, whether or not it has a local strength is not known at all. The Casimir effect is quite well established. Compact extra dimensions and the rest of string theory remain a very good candidate for physics, but are of course notoriously difficult to test. If all of these things eventually work out, then Richard's ideas should work quite nicely. If any of them don't, then all bets are off; I don't know how his analysis would change then.

      Of course, even a few years ago when I heard all this presented, it was much more thoroughly developed. You have my poor memory to blame for a very incomplete and fuzzy account. I have no doubt he's been developing it further in the last couple of years.

        If you can travel faster than light, then you should, by our current scientific understanding (general relativity) be able to travel backward in time. If you can send a message faster than light, then you should be able to send that message back in time.

        It's a bit tough to explain, and it would help to be able to give a diagram, but it has to do with the "light cone" the GP post refers to. If you can find information on a "light cone", Einstein said that anything outside of a light cone may be viewed as

      Perhaps a knowledgable phycisist can clarify: is the light cone thingy a fundamental rule necessary to make our current theories work, or is it merely a consequence following from the fact that our current theories generally do not allow for faster-than-light travel? If the latter, a warp drive wouldn't "violate" any causality rule.

        I'll give a couple of examples, one using special relativity and one involving some general relativity, to amplify a little on what Geoffrey Landis said above.

        Let's start with a couple of definitions. An "event" in relativity means a combination of time and place. Event B is defined as lying outside event A's light cone if the distance from A to B, in light-years, is greater than the time-difference between A and B, in years.

        Example #1: Suppose that faster-than-light (FTL) were possible. Then it would be possible for event A to cause event B, where B lies outside A's light cone. You could simply travel in your FTL spaceship, starting at A and ending up at B, where you'd deliver a message. But according to special relativity, the time-ordering of events is not as absolute as in classical physics, because observers in different frames of reference disagree on the flow of time. Suppose the original setup was described according to one observer, O1, and now we have a second observer, O2, who is moving relative to O1 at an appreciable fraction of the speed of light. If the speed of the relative motion is high enough, then you can always get a situation where O2 says B happened before A, rather than after A. (This only happens if B is outside A's light cone.) So O1 says A caused B, but O2 says B caused A.

        Example #2: In general relativity, wormhole is a possible way to travel between different places, but since time and space are treated on the same footing in general relativity, there's every reason to believe that if wormholes exist, they would also go between different times, i.e., they would be time machines. But let's suppose for the sake of argument that you come across a wormhole that only goes between different places, with both mouths being synchronized in time. This would seem like FTL without time travel. But such a wormhole can always be used for time-travel as well. One method is to use gravitational fields to accelerate one mouth of the wormhole in some direction, bring it to a stop, and then use a similar acceleration and deceleration to bring it back to where it started. When you do this, you get something exactly like the twin "paradox" of special relavitity; the wormholes' times are no longer synchronized. So now if your no-time-travel FTL has been turned into FTL with time travel.

        There's nothing special about these two examples. The idea that FTL naturally makes time travel possible is tightly bound to the structure of relativity. Since time travel seems to lead to causality paradoxes (e.g., going back in time and killing yourself), the conclusion seems to be that FTL leads to paradoxes, and that makes physicists suspect that FTL isn't actually physically possible.

    This article bothers me primarily because it simply recovers old ground on a theory of the possibility of warp travel. The idea of utilizing dark energy to create waves in space-time is hardly new or original and so what we end up seeing in front of us is a series of explanations about possible "space time bubbles" that we have no idea how to create, or even if they're technically feasible, supplemented by a few minor CAD renderings and a wonderful representation of a planar mesh. Pardon me if I'm not entirely enthused. There seems to be no real mention of any progress since this topic was last covered in the scientific press. In short, while a nice idea, it's an old theory and less than stellar (if you'll pardon the pun). This is more science fiction than science, in my opinion.

    Ugh, every thing said in that article is basically a re-hash of the hit parade of technologies that "sounded really good at the time, but don't really work". Casmir effect, Alcuberre warp drive, extra spatial dimensions, etc. are just things that sound neat, but practical applications of them are impossible, misunderstood, or just plain useless.

    I want a warp drive as much as anyone, but I'm beginning to tire of hearing people keep spitting out the same concepts that anyone who can read the Wikipedia entries for them already knows are not practical or are probably not possible.

    Vacuum energy may exist in some form, but the apparatus to generate any significant amount of it would probably take orders of magnitude more energy to operate. No break even. Virtual particles are a hypothesis based on the logic of the Uncertainty Principle, but even if this logic is not simply explained away at a latter point, one needs to only look at what apparatus is needed to demonstrate the Casmir effect to get an idea how you would need to scale in order to get anything out of it.

    The warp drive not only requires us to somehow warp space time, but to actually survive in those conditions. There's only one known thing that combines significant warping of space time with a small area. We call those... black holes. Also, Alcuberre also acknowledged a number of problems with his drive including the fact that it wouldn't be able to see where it was going.

    As for extra dimensions, besides the fact that most places I have read indicate that those dimensions are probably extremely tiny, they would probably require the Planck energy to explore, which no one knows if it is even possible to attain. So, you would spend an incredible amount of energy to be able to go from one side of a quark to another, maybe even quickly.

    Or not at all, considering that a spatial dimension isn't just what's on the other side of a magic wardrobe. Either our 4 dimensions couldn't fit in the smaller ones, or we could, but we'd end up like 2-D Flatlanders walking around in a 3-D world. How could we interact with such a reality? How would it benefit us at all, even if we could survive the experience?

    In the matter of dimensions, there are benefits we can glean from trying to understand if they are real and learning about them, and maybe even the Casmir effect would be good for something like generating antimatter or something. Having said that, planning a spaceship based on these ideas is like planning a ship to sail the Phogiston. It's gibberish, and what's more, its stale gibberish.

    You can start the compression in front of the ship, and also start the expansion behind the ship, which will get it moving.

    However, once you've generated the compression/expansion wave, its self-sustaining. That brings up the problem, just how do you get the forward compression to stop??? What sort of "signal" do you send ahead of the compression wave to nullify it and allow you to stop? According to the Discover article, it "involved some sort of 'anti-gravity'.", which so far hasn't been invented yet.
