I hate to spoil every time travel movie you’ve ever seen, but your misconceptions must be corrected. For the sake of science.
When Michael J. Fox goes back in time in “Back to the Future,” he goes back to the exact same location. Just like what happens in every other time-travel movie. But the thing is, it’s NOT the exact same location. The earth, in its journey around the sun, was not in the same location in 1955 that it was in 1985. It fact, it was millions of miles away the earth’s orbit covers nearly 600 million miles).
So rather than find himself outside the Hill Valley courthouse in 1955 (or 1885 or 2015, depending on the movie), Marty McFly would actually find himself in outer space gasping for air.
This, of course, applies to the Terminator movies, Bill & Ted’s Excellent Adventure, miscellaneous Star Trek movies and TV episodes, and the entire “Time Tunnel” TV show from my childhood.
Whether you go back or forward in time, you’ll end up somewhere in the dead of space. So when somebody invites you to take a ride in their time machine, I advise caution. Just my opinion.
