Stephen Hawking once suggested that the absence of tourists from the future constitutes an argument against the existence of time travel—a variant
of the Fermi paradox. Of course this would not prove that time travel is physically impossible, since it might be that time travel is physically
possible but that it is never in fact developed (or was cautiously never used); and even if it is developed, Hawking notes elsewhere that time travel
might only be possible in a region of spacetime that is warped in the right way, and that if we cannot create such a region until the future, then
time travelers would not be able to travel back before that date, so "This picture would explain why we haven't been over run by tourists from the
future." That's from wikipedia.
Thats just one explanation. I HATE it when people here say I have PROOF of this or that then post their opinions...jealous too, I guess, since they
get the popular threads. Anyway, I'm not a time travel PROPONENT, but you presented no proof. IMO when people title their threads as possessing
proof, and then do not; they should be banned.
