Not to mention that if I recall correctly, on the few occasions where they had 2 of the same person together (and the one case where we see the supposed 'consequence' of 'the same matter occupying the same space') one version of the person is many years older than the other. Given things like how we shed skin cells and they reproduce, etc, the person wouldn't technically be made up of the "same matter" as his duplicate anyway. The same DNA, sure, but not the same matter. If it was the same person from like an hour in the future, I could maybe see the argument for it (but even then it would be stupid), but this is even more absurd. I know some people will argue that I'm "over thinking" things, but IMO this is basic common knowledge, and stuff like this just pops out at me and bugs me when it's clear that they are writing this stuff for the lowest common denominator of viewers.

I'm assuming you're talking about those issues in these movies where the characters always fret about meeting their other selves when time travelling (ala "BTTF II," when the doc exclaims that Marty meeting himself could rip apart the space/time continuum; come to think of it, Biff did it to himself, and everything turned out okay, so I don't see what the problem was ). Yeah, I'm never sure what to think about this.

I can certainly understand the paradox of changing history so that the future changes (and ultimately, displacing the time traveller), but even then nobody's really sure what would happen. Would the traveller exist on a parallell universe of events, or will the universe indeed be destroyed?

Thinking about this just further affirms my belief that time travel is literally impossible anyway (at least for travelling backwards; you could technically move forward all you want via time dilation (ala "POTA"), as long as you have a faster-than-light vehicle).
