This is great finally a place to get intelligent answers from knowledgeable people. Now a hard one: As you approach the speed of light time around you slows down, or your time speeds up. The fastest spacecraft can go 40,000 mph. If you where on this craft although it is a small fraction of light speed you would still travel into the future a small fraction of a second (The only calculation I could find is going at 94% of light-speed, time slows down by a factor of four). Now for the question, when you stop would time sync up?
