It's not surprising that there's a significant number of "Star Trek" fans at NASA, and it can lead to some really cool ideas. Thanks to a loophole in the theory of relativity, a ship could theoretically travel in such a way that the universe moves around it, allowing it to reach far away planets very quickly. There has been some controversy about this theory, and NASA researchers are currently testing to see if it's even possible.
Results have been inconclusive so far, but physicist Harold White says it's only a matter of time before warp speed travel is possible. "Nature can do it," he says. The question is, can we?
