Surplus of matter over anti-matter

[josephwouk]

I'm wondering why I haven't run into a discussion anywhere that uses Feynman's model of anti-matter moving backward in time to explain the paucity of anti-matter in our universe.

Quite simply:

1. The big bang created equal quantities of matter and anti matter.
2. Almost all that was produced mutually annihilated.
3. Those particles that avoided their anti-particle took off in two opposite directions of time.
4. As time passed, they became further and further away from each other in space-time.
5. The seeming paradox, of course, is what happens when the anti-matter returns to the moment of the big bang?
6. But since time itself was also created by the big bang, the anti-matter can never return to it, but instead must continue backwards in time.
7. This makes sense only when one regards the universe as four dimensional and infinite in size/potential size.

There has to be something wrong with this reasoning, or I would have read it. Could someone help me?

Just a thought..
I believe the Big Bang created energy, out of which particles and anti-particles could spring.

The main reason that we have a matter universe and (almost) no antimatter is that there is some difference in decay mechanisms (CP violation). However at present, physicists haven't been able to put together a precise theory as to what is going on.

Try here for some leads: http://en.wikipedia.org/wiki/Richard_Feynman It's at least mentioned in passing...

I don't think anyone knows why the asymmetry between matter and antine matter exists and I'm unsure if current theories attribute any of that to antimatter moving backward in time...

Do you have a reference for Feynmans model?? I have several of his books but nothing on that subject...
