If I had to say one way or the other, I'd have to say that I do not believe time travel is possible. 'Time is the name given to our linear perception of existence', is one thing I've heard (somewhere) that makes sense to me. 'The Past' is not a physical location, therefore one cannot physically travel to it.
Let's say that I was able to travel 20 years into the future. The 'future' that I would find would not be the same 'future' that would have been had I not time traveled. Instead, it would be a future in which my personal influence had disappeared on the day I left, i.e. a future in which I have not existed for 20 years.

The way I see it, IF it were possible (and personally I doubt it is) then if you were to “Travel” in time it wouldn’t be time but simple moving between dimensions/branes/worlds or what ever you want to call it.
So you disappear from this reality to appear in another one. This also neatly avoids the paradox issue as the reality you left no longer contains you and the one you are going to never did contain you!
