Time travel would be possible if it turns out that physics is complete, that the past completely determines the future. But if that is the case, then time travel would be worthless, because you would not be able to change the past using any free will. But entanglement experiments indicate that physics is not complete; that perfect knowledge of the past is insufficient to predict the future, at least in detail. That means that we can exercise some control over the future, which is what you and I try to do every day. Schopenhauer was wrong when he denied free will; his argument was based on the assumption that physics was deterministic. It isn’t.
If time travel were possible, everyone who tried it would die. The entire solar system moves through space. If you were to travel through time, when you came out you would just be floating in space because the planet wouldn’t be in that spot anymore. You would have no way of getting back to the planet, and would just be a sad floating space man until you died.
