| If you went back in time and you
kill your Grandmother, would you cease to exist? But if you cease to
exist, then you would never have gone back in time and killed your
Grandmother. So what would happen? I'm only 14 and I don't know what would
happen. | |

| You're in good company, Amy.
Nobody knows what would happen. Perhaps it would be impossible to create time travel paradoxes. In other words, no matter how hard you tried, you'd find that things would conspire to prevent you from killing your grandmother - you just couldn't do it, for one reason or another. Another possibility is that you'd be able to kill your grandmother, but from then onwards you'd be living in a different universe which you had created by your actions. In this new universe, an equivalent "you" would not be born, but the time travelling "you" would still exist. Your existence would be explainable since you came from a different time line. Yet another possibility is that reverse time travel will turn out to be impossible (forbidden by some undiscovered law of nature). In that case, the problem wouldn't arise. No doubt you can think of other possibilities. Have fun! JR | |

| Wasn't it Stephen Hawking who
said that reverse time travel is impossible by virtue of the fact that we
haven't yet been overrun by people from the future? Unless they're well disguised. Or 1999 isn't a time worth visiting. | |
