I read an article a while back about super-fast neutrinos. Apparently CERN discovered neutrinos that travelled faster than light in one of their experiments, and this proves Einstein wrong, and means that time travel is theoretically possible. Last I heard, scientists everywhere were on a mission to either prove or disprove this themselves, and I haven't heard the latest.
But the thing about time travel is this. Surely if time travel were possible, we'd know. We'd know because we'd be inundated with visitors from the future, right now. Probably in big futuristic tour buses.
As soon as time travel is invented, theoretically any era would be ripe for a visit. And humans being humans, no one will be able to resist popping back to their favourite era. So the fact that we're not seeing time travellers currently, and that there are no extensive records of them in history, means that time travel will never be achieved. Don't you think? Even ruling out the tour bus idea, there will always be someone, someone unable to control their obsessive desire to see who built the pyramids, or meet Jesus, or find out whether the solos in "Flashdance" really were danced by a man.
I've thought this through, using the razor-sharp logic that brought you "Space Rabbits", and have come up with the following scenarios:
#1 Time travel will never be invented. Bummer.
#2 Time travel will be invented but humans will be too wise and wary of the ramifications to use it (NOTE: highly unlikely)
#3 Time travel will be invented and the future humans are among us already, just well-disguised. This might explain the man who looked at me funny in Coles the other day but is probably best not to think about if you have a tendency towards paranoia.
#4 Time travel is indeed possible, however our future selves have never used it because they exploded/moved to another planet/regressed to chimpanzees/became absorbed in the Great Karaoke Wars/are planning for the planet-wide simultaneous performance of Michael Jackson's Thriller dance.
Just a thought.
