Adjustments have radically reduced the theoretical amount of energy necessary to warp space-time

"There is hope."

Those were the words of Harold "Sonny" White at the 100 Year Starship Symposium, an event where science fiction fans and theoretical physicists alike met to trade suggestions and ideas about future starship designs.  Mr. White was talking about his novel warp drive that bears eerie similarities to the fictional drive of Star Trek fame.

I. From Fiction to Feasible

The idea for the real-life version was first hatched by Mexican physicist Miguel Alcubierre in 1994.  Alcubierre's spaceship was a two-part design consisting of a football-shaped spacecraft and an outer ring of exotic matter, responsible for warping space.  

Inside the ring was a bubble of normal, safe space-time encapsulating the ship, but outside it the ring contracted space-time ahead of the ship while elongating it behind the ship.  The resulting distortion of the fabric of our universe would allow the spaceship to travel at a mind-blowing 10 times the speed of light without violating the fundamental laws of space and time.

So what’s the problem?  The amount of energy needed to warp the space was calculated to be equivalent to the mass of the planet Jupiter, the most massive planet in our solar system.  Thus for almost a decade the idea was written off as an interesting theoretical observation, but more fit for fiction than fact.

Then along came Mr. White with an interesting idea -- what if you turned the relatively flat ring into a donut.  The results were astonishing -- used the new rounded ring design, the mass-energy needed was reduced by orders of magnitude to around that of the Voyager 1 probe NASA launched in 1977 -- a small spacecraft.

And by oscillating the intensity of the warps over time, the energy could be even further reduced.

Comments Mr. White in a SPACE.com report, "The findings I presented today change it from impractical to plausible and worth further investigation.  The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab.  If we're ever going to become a true spacefaring civilization, we're going to have to think outside the box a little bit, were going to have to be a little bit audacious."

II. Moving Towards the Stars

Following the new revelations, Mr. White's next order of business is to set up a tabletop experiment at the Johnson Space Center using a measurement instrument they invented, dubbed the White-Juday Warp Field Interferometer.  The laser instrument is designed to detect small warps in space.

Mr. White says of this "humble" experiment, "We're trying to see if we can generate a very tiny instance of this in a tabletop experiment, to try to perturb space-time by one part in 10 million."

Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight, is thrilled by the progress, commenting, "Everything within space is restricted by the speed of light.  But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."

At this point the warp engine is still in its very nascent stages of development.


And yet one cannot help but imagine the words of fictional Star Trek character Zefram Cochrane, Mr. White's fictional analogue:

On this site, a powerful engine will be built - an engine that will someday help us to travel a hundred times faster than we can today. Imagine it: thousands of inhabited planets at our fingertips. And we'll be able to explore those strange new worlds, and seek out new life, and new civilizations. This engine will let us go boldly, where no man has gone before. 

And at that the mind wonders upon the idea of this device floating through the cold stretches of space -- a doubly round manmade instrument in a universe dominated by curvature, creating oscillations of space which are in turn oscillated in intensity with a sinusoidal, rhythmic beat that could one day carry mankind across the stars.

We can't even warp spacetime in the lab, and so it seems like "and an outer ring of exotic matter" (that can bend spacetime) is well beyond practicality. Or am I missing something?

Feasible has a slightly different definition than possible. While they both include the meaning "able to be done", the word feasible implies that it's realistic and workable.

In your example, it's possible that you could communicate with aliens using your laser, but it isn't really feasible.

Perhaps they should try the Bugs Bunny method, of using "Hocus-cadabra" and "Abraca-pocus"?? ;)

The problem with changing lead is that it's a very stable atom (highest non-radioactive, in fact). Much easier to change a radioactive substance by subjecting it to a neutron flux (which is how U-238 is turned into Pu-239).

The trick would be finding the radioactive substance that would decay into gold....

Should drop you back in time a few centuries into the past; and see what people think of your magical electrical vehicles that have no hidden horses, cordless telecommunication devices, advanced medicines, space flight etc'.

You would probably be burned at the stake for "witchcraft" because it would all be imaginary and impossible in peoples minds.

Just remember without great ideas and research and development we would not have anything we have today.

No, you miss the point.
At some point there was no clear definition of warp drive. Science made a definition. Next there were N problems to solve so that this warp drive could be built. One of them was enormous energy requirement. Now this problem is solved. N-1 problems left.
One step closer.
No "Shazaams".

My guess is it would be a rare earth exotic, or a manmade exotic material, that acted as a super conductor, or a large enough super magnet. Which theoretically would be able to warp the membrane of space time like it's showing in the picture.... Oscillating said field, would likely generate the same effect as having a powered wheel turning against a semi loose belt track. I don't know if that's the best analogy to use though.

No, the exotic matter they are talking about would be along the lines of dark matter or super symmetry particles or other stuff that is know by mathematical physical models only (no known real world examples).

Dark Energy might possibly be an example, as that is the sort of behavior the exotic matter would have. May well be that's what dark energy is; the effects of this exotic matter which may be what we call dark matter.

So much speculation though. As you say, there's no solidly known real world examples. But, since they are going to test this in the lab now, it seems we have a hypothesized way to do this without actual exotic matter (or to generate it temporarily into existence for a short time?).

The problem with dark matter is that it is dark because it interacts so weakly with other matter. There is some theoretical proof out is all over, there is just no easy way to detect it because of its nature.
Not to say it wouldn't be a possibility, but with its weak interaction, it would surprise me.

Would something of negative density (which is what exotic matter is, matter with negative density!) be able to interact with normal matter, or light? The idea is it warps the fabric of space-time with its insane impossibility; but conceptually it's hard to imagine negative density matter interacting much or at all with normal matter in a direct sense... hence it might have the properties of dark matter as we see it. Absolute and complete conjecture! There are much better candidates for dark matter, but it's interesting to think about.

Why do you say it interacts weakly? It is true that nobody has directly detected dark energy or dark matter, yet it is very easy to indirectly detect dark energy by measuring the acceleration of the expansion of the universe and dark matter by observing light from distant galaxies being altered by gravitational lensing. Perhaps nobody can DIRECTLY detect dark matter or energy simply because we have not yet encountered any.

Consider a bunch of soap bubbles in the ocean. An observer inside the soap bubble can directly observe phenomena inside his soap bubble. He can look outside of his soap bubble and observe that other soap bubbles are moving relative to him and measure the forces being applied to the other soap bubbles. If he cannot, from inside his bubble, see the water, then he can only conclude that some "dark" energy is affecting soap bubbles. Perhaps a galaxy is a soap bubble of ordinary matter and energy floating in a sea of dark matter and energy.

Now that the Higgs boson has been found, we must consider the Higgs field. Mass is determined by how strongly a particle interacts with the Higgs field. We usually consider a particle, say an electron, to have a fixed mass. However, that is only true in a uniform Higgs field. What if the Higgs field is not uniform. The same particle would have a greater mass in regions of higher Higgs flux than in regions of lower Higgs flux. Now if we move a particle from a low flux region to a high flux region, then it's mass increases. Since E = mC^2, then either energy is not conserved or the speed of light increases. But wait! If we move it back into the low flux region the mass returns to what it was before. So did we gain and then lose energy, thus preserving the conservation of energy, or is the speed of light dependent on the Higgs field as well?

We don't know, because nobody has been able to reconcile the standard model with general relativity. Something is missing, and we are basically waiting on the next Einstein to come along and discover it.

Of course it's fantasy, but it's still "possible". The science behind it is sound.

It's just at the moment there are massive seemingly insurmountable engineering challenges in actually making a working "Warp Drive".

But then again, so was breaking the sound barrier at one point /shrug.

What are you talking about? I warp spacetime, you warp spacetime, we all warp spacetime!

It's called... gravity. :) The mechanism for a device that allows you to use it for travel, well, that's a bit complex but entirely plausible. You have to stop looking at gravity as a pure "force" (even though it is one of the four fundamental forces) and more as part of the fabric... or a way to interact with it.

You are missing something. We have the theory, we have the ability to use a much smaller and realistic amount of energy to test that theory. Now it's only a matter of doing and experimenting to see if this holds any water. That's what the lab work is investigating right now.

If they succeed, even in the smallest way, to detect a space-time bubble during the experiments meant to test this theory, then FTL travel will be a matter of when not if.

This is how science works; and the warp-bubble theory as just moved from science-fiction (where things like String theory still reside) to science now that we can test it directly.

There is a pretty wide gap between what is theoretically possible and what is actually possible. It's the difference between having and not having fusion power, teleportation, direct computer/neural interface, or true artificial intelligence today. And I'll definitely continue to file 'FTL travel' right there amongst other ideas nowhere near implementation. Not saying it can't or won't be done, but we've no present reason to think it will happen in our lifespans.

Sure, we have no reason to think it will or won't happen in our life spans. But, this now makes that "gap" not so wide, and puts it more on par with the hot fusion gap (something that can be tested and refined, but cumbersome).

If we can actually test it experimentally, then it is now science, and no longer conjecture; that's the real breakthrough here. And we know the speed science can work at once it sinks its teeth into something. Of course, the experiments may well falsify this theory instead!

Hopefully we will find out one way or another very, very soon.

Because it is fantasy. Fundamentals on which these scientists are basing their calculation/prediction is WRONG. Time is not a dimension. Space wrapping does not happen like they think they do. Worm holes do not exists because science got the most fundamental question of what is space/existence wrong. The closest the would ever see a phenomenon that behaves like a worm hole is at the poles of a black hole. And u cannot travel in it.
And unfortunately yes we are in an inescapable count down to nothingness. Well it is too far away for us to care but its inevitability is also true.

As a Ph.D. Physicist, it also seems like a fantasy to me. I don't think we know enough about the space-time "continuum" to assume that warp drive is physically possible. It would help if there were any evidence, such as black holes suddenly disappearing, gravity waves from warp transitions, objects popping into existence, or space aliens warping around the galaxy.

The experiment will probably produce results and conclusions along the lines of the Michelson-Morley experiment. It is hard to observe space-time warping or absolute frames of reference when your instruments are intrinsically part of the thing you are trying to measure.
