The astronauts aboard Apollo 13 actually time travelled a few microseconds into the future because the speed of the rocket slowed down their personal body clocks according to Einstein s theory of relativity
OK, to clarify, my point was the slow down of their "personal body clocks" was relative to everyone else on the planets body clocks. They didn't time travel, it was a slow down of individual "personal body clocks".
and yet they celebrate moon missions instead of time travel. also the computing systems in an iPhone are more powerful than the ones used to run the Apollo 11 mission.
It's easier to cross the border from any state in CST or EST into a state to the west which is in the next time zone....and you'll get an hour in the past instead of minutes.
