It seems if one could travel at the speed of light, they would never age. Time stops. So if someone wants to slow down the aging process, say compared to their friends, they need to take a trip as close to the speed of light as possible. Contrary to that, many young children cant wait to get older. Does standing as still as possible make time pass the fastest, or is their a way to make someone age even quicker. Not sure how to state this, but is there something opposite the speed of light that would make one age instantly, or is standing perfectly still the fastest time can pass? Thanks for any help on another dumb question that interests me.
