Quantum Setback For Warp Drives [back to the drawing board]
Slashdot ^ | 4/3/9 | kdawson

Posted on 04/03/2009 8:50:10 AM PDT by Clint Williams

KentuckyFC writes

"Warp drives were generally considered impossible by mainstream scientists until 1994 when the physicist Michael Alcubierre worked out how to build a faster-than-light drive using the principles of general relativity. His thinking was that while relativity prevents faster-than-light travel relative to the fabric of spacetime, it places no restriction on the speed at which regions of spacetime may move relative to each other. So a small bubble of spacetime containing a spacecraft could travel faster than the speed of light, at least in principle. But one unanswered question was what happens to the bubble when quantum mechanics is taken into account. Now, a team of physicists have worked it out, and it's bad news: the bubble becomes unstable at superluminal speeds, making warp drives impossible (probably)."

I think reality burst the bubble on this one.

Rats. That was our technicality in FTL. Of course impossible in current technology, it still provided something to strive for.

Wormhole theory, however, remains sound. I truly think someone will cook up a traversable wormhole before too long. I hope I live long enough to see it.

Ummm..., yeah..., if one believes in science fiction physics... LOL...

I can think of a few personalities I hope would volunteer to be the first to travel into a black hole...

There is actually a speed EVEN FASTER than Warp Drive speed: Ludicrous speed.

And if you go that fast, don't even THINK of STOPPING. You have to SLOW DOWN first.

The current admin reminds me of Spaceballs. With Barry as Pres. Skroob, Emanuel as Dark Helmet, and Hillie as Col. Sandurz. With the three of them surrounded by...well, you know :)

As long as we keep striving, we achieve. If we stop striving we stagnate.

Isn’t the whole notion of a wormhole that the space within one event horizon of a black hole may transmit matter/energy to another black hole? If so, the speed of light is only one of many facets to your problems.

Wormhole physics are perfectly legitimate. None has been found, or probably will until we get out there using some other method of transport, but there are no reason they can’t exist when using general relativity physics.

If some of the string theories or multiple universe theories turn out to be accurate, there are a number of other possible options for getting from one place to another without crossing the intervening space. Possibly by taking a shortcut thru another universe.

Yeah, perfectly legitimate in the “minds” of some people... :-)

Couldn’t they just “beam” us to wherever we’re going? You know, “beam me over, Scottie” rather than “beam me up, Scottie”?
