Oh yeah, absolutely. Like I said, there's no other theory that's scientifically valid. But that doesn't mean that it's correct.

Consider the concept of egocentrism and get back to me.

consider shutting the fuck up

thanks

Consider getting some fresh air.

Thanks.

i already have some fresh air

what should i do with it?

Hold your breath so it lasts longer.

There's a new-ish theory in quantum physics called "retrocausality," or the idea that time travel is quite ordinary:

After the big bang, the universe could have formed any number of ways... the vast majority would have led to a highly unstable universe. If the weight of the electron was a tiny bit different, Hydrogen atoms would not exist. The universe would be a boiling cauldron of chaos.

This new crazy theory is that we live in a "self tuning universe," with particles going backwards in time to adjust the big bang to ensure a more "stable" universe... one in which suns warm planets, ice floats, and clusters of self-replicating water bags of low entropy (aka life) is possible.

i'll consider it

See? Greg Hill could TOTALLY be from the 23rd century.

Fucking duh.

I've always liked this sort of thing. It fits with the only theory of time travel which I find to be even remotely sensible, which is that if one goes into the past with the intent of changing something, one must always either fail, or create the same event which already happened.
