Well... the only 'Real' way I can think of is possible "Paralel dimensions'... Where the alternate reality for what ever reason is experiancing 'TIme' at a different/slower rate and hence is 'behind us' in events.
I think I read somethng by Pratchette? Maybe a New Scientis? that time travel is not possible because of the 'Matter can't be created or destroyed' thing.
Effectivly you'd be taking 'Matter' from 'Here', effectivly 'destroying it' and thence putting it back 'There', hence 'Creating it'.
Not sure if I understood the idea completly or even remembered it correctly.
Still, cheers.
Not at work.
