ost_uid0]I guess so, but I don't like doc's theory. It implies that if you could ever travel through time, you still better not (and that's a major understatement) because if anything goes wrong, all of mankind would never have existed. It's pretty pessimistic.[/quote

This is why time travel movies/episodes are full of paradoxes. If they couldn't do anything that would cause a paradox, there would be no good movie/episode.
However, has anyone read Harry Potter and the Prisoner of Azkaban? In that book, Harry and Hermiony's time travel has only one paradox. A predestination paradox, because Harry saves his past self's life. Other than that, the story is sound.[/color
