$this->bbcode_second_pass_quote('threadbear', ' ')I also think it's perfectly legitimate to assume there are actual time travellers among us. I would assume they'd keep as low a profile as possible, though.
Why?
If the “infinite worlds” theory of time travel holds, then why wouldn't you just go “back” and screw things up for fun then go to a timeline where you didn't screw thing up. If you have 1 time traveler and infinite possible destinations then you have a 1/infinity probability of being in a universe with a time traveler... ie 0% chance. If you have 100 billion time travelers, you get the same probability.
If the “single timeline” theory holds, then nothing you can do back in time will change what happens in the “future” because only one timeline exists. So we would see many “time travelers.”
More likely, time travel won't work in any universe because the past and the future don't have any reality. We exists in a universe that has an instantaneous past linked to an immediate future separated by 1 plank interval in time. Everything else serves as semantic window dressing.
Titor just played into our hopes and fears because he got drunk one night and hatched a little scheme (read his first posts where he admits being drunk on his first “day back in time”, nice guy to pick eh?) People spent years wringing their hands over it and the most ardent believers who researched it ended up finding out that he's just some guy on the internet, like everyone else said.
I don't understand why this keeps coming up.
