We exist in the universe, with space and time. Without space and time, there would be no motion. If there is no space and time outside of the limits of the WHOLE(not just visible) universe, is it possible to have anything existant outside of the universe? If nothing can exist outside of the universe, does that mean there is nothing outside? Implication of last question: Is there an outside, or is our universe infinite/looped? Because how can anything be existant when there is no time to start it?
