Off Topic: Warp Drive
The dreamers at the British Interplanetary Society are thinking big today. They're hosting scientists and engineers from around the world who are studying the theory behind warp drive -- the propulsion system that powers fictional starships. They may not be sending anyone to Vulcan anytime soon, but they are learning more about how the universe works.
About a decade ago, a scientist named Miguel Alcubierre came up with a theoretical basis for warp drive.
He used Albert Einstein's theory of gravity to formulate a "bubble" in spacetime.
