i know about hawking radiation; I'm pretty sure it's do to the fact that antiparticles are regular particles going back in time, and vice versa, not entanglement.
Antiparticles are basically normal particles but with their electric charges reversed (a positron is the antiparticle of an electron, with the same spin and mass, but positive charge instead of negative). As far as I know, nobody has theorized that antiparticles go backward in time, and the only way I know of that a particle could go backward in time is to go faster than light.
It's an idea that Feynman mentioned (somewhere; maybe in one of his books) bringing up with thesis advisor. It's interesting in that it would explain why all electrons have the same mass, charge, and so forth -- they're all actually 1 particle which 'bounces' between going backwards and forwards in time. His advisor, though, pointed out that it only works if there are the same number of electrons and anti-electrons in the universe, which doesn't appear to be true.
