Science Still Has a Lot to Learn From Star Trek

18 Jun ’05

News from the BBC today that researchers have developed a new model of time travel that uses quantum mechanics to explain one of the more difficult paradoxes of time travel – that if we were to travel back in time we might disturb the past, which might change the present.

The new view seems to be – er, well – you can’t change the past – that’s why they call it the “past”.

Is there more to this than smart-alecky physicists, trying to see whether we’ve been paying attention to Star Trek (which taught us that we can change the past – just as long as we change it back before we return)???
