I'm thinking of a way to defend my authroity against a peer who has threaten to take me down in a debate (LOL). Im Im thinking, say your moving close at the speed of sound, and then you suddenly stop, time around you is supposed to get slower, and potentially go back in time. How would it seem to be an observer? WOuld you seen slower than you actually are moving? Would everything int he universe get slower to keep up with you speed? That would form a paradox, just about everything int he universe is moving at different speeds, how would this be possible? My question is would it be possible to have 2 different times in two different places? If not... then say after this 'trip' the two people (observer and the runner) meets up, would the runner meet the observer in the past? This concept, i jsut cant understand.
