[quote="Cpt. Obvious":2f2a8]There is also the thing that contradicts every time travel movie. If you go back in time to change something and you do, you would have no reason to go back in time again. And thus leads to a paradox of possibilities such the destruction of the space time continuum(sp).[/quote:2f2a8]
they supposedly dont exist anymore. IT gets a little complicated but il ltry to explain the MUltiverse theory.
In a nut shell theres not just one universe but an infinite amount. In each one theres some very small detail thats different. "time" is actually the passage from one universe to another. IF you have just tim flowing like a river there is no place to travel to. Yet if you have universes that "time" travels though the nyou do have a place to travel through. This all cancels out the efect of the dreaded paradox because there is a universe for everything. ONe where Hitler wins the war and one where he loose but lives, another where he wins and dies, another where he dies and loses. SO according to this theory he could be from another universe where this does happen but he came to our where it wont. so if his shit doesnt happen and he reads up on this theory I can almost gaurntee you he will be back saying we must have lucked out. thats just a briefe overview. I think I covered it good enough
