Travelling backwards in time is not possible, it's obviously not possible, and it's a wonder that the idea gets given such credence in educated circles, apart from it being a nice thought and a diverting intellectual exercise.
Actually, time travel is real. My name is John Titor, from the year 2036. I'm looking for an old IBM 5100, does anyone here know where I can find one? The future of the world depends on it!
