Warp Speed? There's Just This Problem... | Discovery News Video June 11, 2009 -- "Star Trek" makes faster-than-light travel look easy, but according to new calculations by Italian physicists, a warp drive could easily create a black hole that would incinerate any passengers on a space craft and then suck Earth into a black hole.
"Warp drives are so far the best case scenario to attain faster-than-light travel," said Stefano Finazzi of Italy's International School for Advanced Studies. This paper "makes it much harder to realize, if not almost impossible, warp drives."

In normal physics, nothing can move faster than the speed of light. Einstein's theory of relativity forbids it. In normal space any object approaching the speed of light will increase in mass exponentially, and require an exponential increase in the amount of power needed to propel it forward.
There are two exceptions to this rule however. The first is what's commonly called a worm hole, a bridge connecting two different parts of space. A ship crossing this bridge would move at below light speed, but still arrive before a beam of light that would have had to go the long way around.
