I have recently seen the movie K-PAX starring Kevin Spacey. In it he is supposedly from the planet K-PAX and goes onto explain how it is a few thousand lightyears away. The doctor questioning him wants to know how he got here and he said he harnessed his energy onto a beam of light or something to this effect. He then said that they would travel and many times the speed of light and when told that Einstein said that nothing can exceed to the speed of light he told the doctor he was wrong. That what Einstein really said is that nothing could exceed up to the speed of light because its mass would become infinite but that Einstein said nothing about entities already travelling at or above the speed of light. Anyway, does this hold any water? What do you think about this? And to anybody who has seen the movie also, can you point out some interesting physics about the movie?
