I have come across the problem of infinite mass at light speed, but I think I may have the starts of a solution. If you remove yourself from the fourth dimension temporaraly, and then move about within the confines of the three dimensions, and place yourself back into space-time, you may have moved a finite amount of space in an infinitesmly small amount of time, thus speeds far greater than light are attained. Problem is how do you remove yourself from space-time? I have no idea! If you could tell me, your thoughts would be greatly appreciated.
