Continuing OT:
Also, Warp Drive (yes, as in Star Trek: for the original series Gene Roddenberry had REAL scientists as technical advisers and got in touch with a lot of people at NASA and the military about coming tech, and this continued in Next Generation) is scientificly valid. With Warp Drive, the ship does not move, but rather the space around it is moved, and, therefore, speed of light restriction does not apply. Further, while in the warp bubble created by warping the space around the ship, time does NOT slow down, but remains unaffected, hence, one can effectively travel exponentially faster than the speed of light with none of Einstein Theories' limitations or effects.
