We end up at the same destination no matter the choice we make. For an example, if you could go back in time and try to change the future, it wouldn't work. You would just be contributing to what already WILL happen. It may happen a different way, thanks to you, but it will happen. If you could do this, it still would not work, because for this to make sense you would end up not even existing in the first place (Since you have already experianced it happen once THAT way). I can't really put this in words well.
So you obviously believe in fate and not causality. I believe that if you could travel back in time events would change. However I don't really believe that it is even possible. Take the grandfather theory for example. Say you went back in time and then shot your grandfather. Therefore you would never have existed at all, which means that you wouldn't be able to go back in time and kill him, which means that he is safe, which means that you were born...... it goes on and on. It's a problem that has two completely different outcomes at the same time. Scientists say that the theory becomes so complex that it proves time travel is impossible. So now there's the theory of multiple universes. Yeah...sure.
I don't really know where that came from, but I said it anyway. How's that for off topic?
Kevin: Remember that one time when I ate those napkins?
Me: (laughing) Yeah.
Kevin: That was funny. Do you remember what made me do it?
Me: I'm pretty sure you just said, "Hey, watch me eat these napkins".
Kevin: (laughing) Yeah, that sounds about right.
the grandfather paradox only means that somehow events will not occur that allow you to kill your grandfather but physics does not exclude time travel. And multiple universes are not that out of the question - why not?

Well, it is science's biggest problem with time travel. I don't know about the whole multiple universe thing. It's not out of the question, nothing is, but it does seem pretty out there to me. If you could travel into another universe and through time, it would destroy energy conservation and causality.
In order to travel back in time or forward just a little, you would have to travel faster than the speed of light, which is physically impossible for anything that has mass. A nutrino can't quite do it, and that's something that has virtually no mass at all.

Not really, conservation of energy is kept in check by taking the entire multiverse as one worldmap like thing... the entire thing is self contained and is destined to play out every possible combination of movements of all particles since they all are in multiple states at once.
Indeed there is no problem for energy conservation. Causality is not fundamental.

I guess I believe in choice and causality in a way. Choice as in, you make a mistake and learn from it, so you make a better choice next time. And fate as in if you don't make that choice in the first place, you're damned to the same fate each time (If you went back in time).
