Warpspeed teoretisk möjlighet

En Warp Drive-motor är inte en omöjlighet:

It is possible to travel faster than light. You just wouldn't travel faster than light.

Seems strange, but by manipulating extra dimensions with astronomical amounts of energy, two Baylor University physicists have outlined how a faster-than-light engine, or warp drive, could be created that would bend but not break the laws of physics.

"We think we can create an effective warp drive, based on general relatively and string theory," said Gerald Cleaver, coauthor of the paper that recently appeared on the preprint server ArXiv.org

The warp engine is based on a design first proposed in1994 by Michael Alcubierre. The Alcubierre drive, as it's known, involves expanding the fabric of space behind a ship into a bubble and shrinking space-time in front of the ship. The ship would rest in between the expanding and shrinking space-time, essentially surfing down the side of the bubble.

The tricky part is that the ship wouldn't actually move; space itself would move underneath the stationary spacecraft. A beam of light next to the ship would still zoom away, same as it always does, but a beam of light far from the ship would be left behind.

(...)
Cleaver agrees that the creation of a real warp drive is still far away.

"Warp drive isn't doable now, and probably won't be for the next several millenia," said Cleaver.
