Well, I have a hypothesis. You can go at the speed of light, if you have the right acceleration, balance, control, and direction and angle. If your going down a very steep hill approximately 2,000 miles high (which is possible) and your going on a bus/car/motorcycle you can reach the speed of light as soon as you are 1 mile away from the ground (if you go perfectly straight), and as soon as you do, Like you said before Dan, The person would explode. Although, my real hypothesis, is that the person would only appear to explode, but instead, the person would break up into tiny bits of material, that would travel through the space and time holes, until it stops moving at the speed of light, in which that current moment, the being would end up in another period of time depending on how fast they went, and how long they went. Either that, or the person would be lost forever, but would be living his/her life in emptyness. That's just a hypothesis, though.
