Has anyone thought of this: our planet is moving, the solar system is moving, the entire universe is moving, at very very high speeds. So if you only move forward or back in the time dimension, u will mostly end up in empty space. If you are really unlucky, in a star.
Even assuming time travel is possible, you have to propell yourself through vast spans of space. And the universe is still expanding. So this problem is not a smal one to resolve.
Personally, I am inclined to believe that nature will do whatever it can to resolve paradoxes. If you are interested you can look into quantum physics, specifically electron diffraction and what happens when you have a device that can track the electron through the 'diffraction grating' to see a very intriguing example of how nature prevents paradoxes.
If we've reached a point in time where we are capable of time travel, I'm pretty sure that we will be able to factor in that stuff. Yes, those are some pretty complex equations, but hey, I'm sure we'll have robots and stuff in the future to do it.
I personally don't think time travel is possible, or at least if it is then the people from the future have very strict rules about it. Like, who wouldn't abuse that power? I sure as hell would.
(Actually, what I'd probably do if I had time travel powers is go back in time and kill myself, just to see what would happen)
