'Philip Mak' spoke:

Well let's see... if speeds beyond c = 3*10^8 m/s were possible, it would 
be possible for an observe to observe an event happening, and then 
prevent that same event from happening. I don't remember the exact 
details, but this is possible (I saw a Star Trek tech thing).

I once took a non-credit HS-level course on SPecial Relitivity  at MIT.  The
entire course was about this stuff <bleah!>.  Don't ask for any of the math, I
don't remem,ber it, but what happens is that as u approach c, the time you
experience in relation to the universe is slowed down to nothing @ c.  Once
you go beyonud c, time seems to go backwards in relation to the universe,
meaning time travel.  What your describing is a paradox, which this whole
topic has more of then I'd care to remember.  I've found that the ST writers
have a tendency to stretch the truth about some things, so you can't always
believe what they say.
