Time Travel

While not as good as this, the BBC wrote a very good article about time travel, with the exception of one paragraph: "Clearly, the present is never changed by mischevious time travelers: people don't suddenly fade into ether because a rerun of events has prevented their births - that much is obvious." Ummmmmmmm... if their births were prevented, we would not remember them at all--they never existed and thus our memories of them could not have formed. There was a Twilight Zone episode that excellently illustrated the impossibility of time travel. What we know as the past is the past with "future" time travel's influence already there; it happened in the past.
