Faster than the speed of light?? As I understand it, according to GR, E is directly proportional to M. Therefore hypothetically speaking, if one did have an unlimited supply of E to enable matter to travel as fast as C, M would become infinite, and travel would not be possible. However if one wanted to isolate M from the E=MC2 equation, would it not be re-written as M = C2\E, thus making M infinitely small? Please correct me if I am wrong here! Also, what experiments have been carried out to support GR and exactly how fast has matter travelled to date? Finally, again hypothetically speaking, with an unlimited energy supply available, would one be able to transport space around the matter so theoretically the matter would be stationary and the space around it would be travelling as fast as C.
