Trippy's Theories on Psyche, Time Travel, and Fate

[g-boy]

What you refer to about time travel is what we call the grandfather paradox. If you go back in time to kill your grandfather, you'd never exist. If you don't exist, how could you kill him? Some claim that if you find time travel, then you go into another dimension. I think we already had a similar topic way back, I don't feel like talking about it again, seems overdone.

By the way, the movie Timeline is based on an awesome novel by one of the greatest sci-fi writers, Michael Crichton. Unfortunately, the movie hacked apart the book. Read the book first, then see the movie would be my suggestion.
