my own thoughts on time travel go like this:
if time travel is possible AND you can alter the course of history
THEN time travel will never be discovered.
my reasoning is that if you can alter the past then one day
someone will screw up and the discovery of time travel will
be deleted from history. in a small puff of smoke the whole of time
disappears up its own rear end :-)
the possibility of time travel with NO history alteration implies
that effect on YOUR past have no effect on YOUR future. time lines
and parallel universes and all that.
one thing i could never understand at university was why when time was
just another coordinate in 4-space, could you not move in a negative direction.
probably just my lousy maths ability :-) (don't listen tcdmath)
