Yes. Personally (I don't know if this goes with any theory, it's just random conjecture), I believe that if we went back in time and changed something, and went back to our own time, nothing would change. The reason being that one can't go back in time in their own dimension, so they instead end up going to another dimension that's at the time period they desire, and change the course of history in that dimension. It's weird and complicated, and I'm not even in college, so it's probably bull :-w . Oh well. Here's my thoughts on the time travel paradox thingy. Every-thing in the past has hapened. The future is the further future's past. You could go back in time and kill every one you met, but you could not kill you parents etcetera becuase your parents have already made you, in the future's past. If you go back in time and do some-thing, then go back, nothing will change, because you already went back in time before you went back in time. [YAY]If you go to the future, you may or may not be there: If you are, then you are going to go back in time, grow up and meet yourself. If you aren't, then A) You have died in the past. You can still go backwards and meet your future self before you die. You will then start again from every-thing after the [YAY] (note, future meaning from your original time) OR B) You do not get back to your present time. You can still go forward and look for yourself, if you do, go back to the [YAY]
