Just something I found sifting through some un-opened e-mails from a few weeks ago:
Could a Warp Drive Engine Travel Faster Than Light?.
Two Baylor University physicists believe that if the 11th dimension could be shrunk behind a spaceship it would create a bubble of dark energy, the same dark energy that is causing the universe to speed up as time goes on. Expanding the 11th dimension in front of the ship would eventually cause it to decrease, although two separate steps are required. One slight problem though is exactly how the 11th dimension would be expanded and shrunk is still unknown.
