There have been many movies, television shows, books, and short stories in which someone travels forward or backward in time. There are four little problems that none of these stories seem to take into account:
- The Earth revolves on its axis at about .5Km/Second
- The Earth orbits the sun at about 30Km/Second
- The Sun orbits the center of our galaxy at about 230Km/Second
- Our Galaxy orbits the center of the universe (wherever THAT may be) at about 640Km/Second
Adding these figures together, the Earth, and everything on it, moves about 900Km, or 559.23 miles in one second.
These figures come from This page at cornell.edu.
This means that if you were to step into a portal that transported you back in time just one second, then you would step out of that portal almost 560 miles away from the Earth. Here’s hoping you brought your space suit with you.
