Ok, a close friend and i crash at each others place, and when we finally decide to sleep, we turn everything off, and suddenly start talking, and stay up for a few more hours. however, one time we got into a very heated debate about Time Travel. i deem it to be impossible while he deems it to be possible. however, neither of us win.. we just end up laughing at how ... impossible out suggestions become and how flawed the reasoning is.

However, i would like to hear your own opinions on the matter, and i really do hope to get a large response and lots of reasons for both sides.
