    We're a few days now removed from the season finale on "LOST," I'm thinking - Is time travel possible? Even theoretically?

    I know it makes my head hurt to even think about, but I remember reading when I was little books about the paranormal where people allegedly stepped back into the past briefly, etc., etc.

    What does everyone think? Any amateur physicists/science fiction geeks on here with some ideas?

    Not anymore, what, with the clock tower from Back To The Future having been burned to the ground.

    Time travel? maybe

    Is it a lot easier to get from one end of the universe to the other than what we think right now? I would almost guarantee it.

    In 10,000 years we will look like a caveman with a wheel to our descendants.

    There have been some toy experiments in which, at just the moment that the time machine is actuated, the universe conspires to blow it up, which has led Hawking and others to conclude that nature will contrive it so that time travel never in fact occurs. But no one actually knows that this is the case, and it cannot be known until we have a full theory of quantum gravity, which we do not seem to be on the verge of yet.

    Wow, that sounds a little bit like Lost.
