Yup. That's why I say time travel is infeasable outside our Solar System. Even within, the calculations to not wind up inside the Sun, planets, or space void is beyond our current technology. Still, I love time travel movies.
‘Time’ travel is, at best, a sci-fi myth.
Everything in the universe is moving. If you were to ‘travel’ back in time, or forward for that matter, just one second, you would wind up in a complete intergalactic void, and be dead in a few seconds, unless you had a life support system.
Use computers to ‘offset’ the movements? Too many variables to allow such computations to be very accurate to within a distance of a few thousand miles, much less inches.
Another more compelling reason is mass.
The universe has a certain amount of mass and energy. If you travel to another time, forward or backward, you would increase the ‘mass’ of the universe, because ever atom and subatomic particle of your body has always been around in some form or another since the beginning. T travel to another ‘time’ your atoms would then be duplicated, which is a no-no. To offset the duplication you would be immediately turned into energy. >>>> BOOM <<<<<......................
