If it is possible, something would have happened already that would skew our past and there would be some sort of energy transfering or some way of interconnection like in the movie called "The One".

... what the **** are you babbling about? Have you even read this thread? What's this **** about the movie The One? Why are you people all quoting movies? Holy god, this is retarded. This is supposed to be the "critical thinking" forum...

Reach, I don't know, maybe the movie diverged from the book quite a bit, but I know the book certainly didn't have any of that. The reason I was talking about relativity was because that also meant that people didn't know anything about the whole speed of light barrier, time dilation, etc., and so hadn't actually needed to think much about time in terms of science except as a linear progression along which to measure data.

As for there being nothing solid in this topic - the theory of general relativity was the first to propose time as a dimension on par with our three spatial dimensions, a proposition which is now pretty scientifically accepted. I think this is pretty important in any discussion of time travel, because it brings up somewhere to at least start looking at it and reasoning about it.
