<p>So Adrian, are you saying that FTL flight wouldn't involve
time-travel?</p>
<p>I thought that under certain circumstances it would (specifically
FTL travel to a location that was accelerating away at a
significant rate relative to the point of departure, then FTL
return. I think). Or is there no problem, and it's just the simple
fact that nothing with mass can travel at, or faster than,
light-speed that stops us being able to do it? (and tricks like
Acubierre Drive, if it could exist, would work without causing
paradoxes)?</p>
