We are all time travelers, but is "time travel" is a silly idea? IMO we are just moving to fast. The net is about 1M/ mph toward the constellation Leo, but there are all the other rotations to account for to. So you want to go back in time 10 days - that's 240M miles, and sorry there's nothing there right now. Forward seems OK, but you better be fast and navigate really well unless you want to live in empty space and many other problems, e.g., how to slow down, fuel, not running into things you don't know about. There's the worm hole thing, but I think I read that would take more energy than just normal travel to create. Who has the answer?
