      Hi purplewolf9,

      Yes, but only forward 🙂

      Actually, I seem to recall that time travel isn’t theoretically impossible from our current understanding of physics. But actually traveling in time – that’s a whole different kettle of fish.

      Interestingly, some people argue that time travel isn’t possible because, if it was, people from the future would have visited us already. But then, how would we know we were being visited by people from the future?…

      Physics again. I honestly don’t know. This is one of those questions that sounds neat but the answer is loads of incredibly boring maths. I’m going to wait until somebody does that massive sum and says yes or no. People will waffle about theroretically this and that but that’s just nonsense. Anything’s possible…Anything.

      Well, I know plenty of physicists say NO, absolutely not. Sometimes I think I understand why… other times it makes less sense.

      I tend to think we don’t really know everything or entirely understand space-time yet, so maybe it is for some life forms, perhaps it will always be impossible for us though?? Thinking about time paradoxes (well if I go back and kill my grandparents by accident I won’t exist, but if that happens, I’ll never have existed to do it… argh) can be fun but I like to stop before my head explodes.
