    Well, since this was posted in Science Memes, I’ll be so pedantic that science does not support the idea of travelling back in time.

    It does support travelling forwards in time, at various speeds, but you’ll constantly be aware of where you are (even if one method involves travelling really fast and therefore may still leave you in empty space).

      if you believe in the notion that the universe is cyclic then you can mimic time traveling backwards by traveling forwards, past the end of the universe, and stopping at just the right time in the new universe.

      e.g., to get to 1700 you’d go (present time) -> (death of the universe) -> (1700 in next universe)

        I mean, personally, I actually don’t believe that the Big Bang created everything out of thin air vacuum, because much like travelling backwards in time, that would break causality.

        It makes much more sense for everything to just have always existed and the Big Bang is merely a very visible event + expansion afterwards.
        I’m open to the notion that expansion and contraction happen in some sort of cycle, because well, many things do.

        But for it to be cyclical to the point where it repeats precisely the same? Why?
        Can’t we just let the universe flobber on its merry way without assigning some higher meaning to everything it does?
