The first two are theoretical. Please excuse grammatical and spelling errors. If you had a spaceship at the edge of the universe, and this spaceship could travel faster than the universe is expanding, what would happened if you tried to travel outside its boarder? Would you crash into the boarder like a brick wall? If you had a satellite one light year away, that had amazing video capabilities so much so that when pointed at the earth you could see people moving. And somehow you were able to access this video feed faster than the speed of light, would this be a mechanism for looking into the past? I heard that black holes are much like the concept of a mathematical singularity. The center (if you will) of a singularity is a point. Are the center of black holes points (in the Euclidean sense "that which has no part") or does the center have some substance.
