Re: It all went the other way...

"That would help to explain the "ultimate free lunch" aspect of the Universe.
+Universe + -Universe = 0""
So it kind of looks like this:
Created ------------------------> Particle -----------------------> Annihilated
(Energy Input) ........................................................ (Energy Output)
Annihilated <--------------------- Anti-Particle <------------------ Created
Extrapolating that ultimately as far as it will go gives us not only a perfect explanation of how the Universe begins and ends, but also puts to rest the old chestnut of "what caused the Big Bang".
Created ------------------> Universe --------------------------------> Annihilated
(Big Bang) ................................................................. (Big Crunch)
Annihilated <--------------- Anti-matter Universe <---------------- Created
Since a release of energy (or explosion) with an arrow of time reversed looks like a condensation of energy (or implosion), we see that the Big Bang is a Big Crunch in reverse, and vice versa. Unless there's a Big Bounce in the middle and the Matter and Anti-matter universes both undergo a Time Arrow reversal. Which kind of explains where all the anti-matter is - it's us, in the Future.
