But let's just say it's the Star Trek universe and some anomaly is located in deep space. How would that anomaly be tracked? We know locations based on the positions of other bodies and those positions are always changing. So if this wormhole was next to Saturn, would it still be next to Saturn in a year or would we have no idea where it is because Saturn and the rest of the solar system has moved?
Likewise, let's take a look at Back to the Future. Marty travels back in time 30 years in Doc's DeLorean. If Marty is at the Twin Pines Mall and instantly travels back in time, what keeps him at the mall's location? Would he not travel back into empty space because the Earth wasn't right there 30 years ago? If he were to travel back in time one minute would he find himself in the Earth's crust?
I realize these are both movies and you have to go with it. But this is what keeps me up at night.
