Thanks Neutralino;

You solved my mystery.

Best,

Pat

P.S Wouldn't that be further evidence for the big bang model?

I would think that we would get several billion photons for each annihilation pair of particles; not just 2 photons!

Indeed, the CMB radiation is one of the "pillars" of observational evidence. Firstly, the fact that the CMB exists is good for the BB theory and secondly, the fact that it exhibits a perfect black-body spectrum is further evidence.

Hmm... I'm not sure I follow. When a pair annihilates it creates two photons.

Well no more antimatter universe for me, you just accounted for everything. I didn't like the asymmetrical theory built into the "Big Bang" however, you are a great accountant Neutralino.
Being one myself I mean that as a compliment.

Best to you,

Pat

Sorry, I thought I'd replied to this thread weeks ago!

Anyway, thanks for the compliment. And yes, not many people like the fact that the laws of nature seem to favour matter over antimatter; especially since we don't know why! This is a field in which current research is being undertaken, so we may know sometime soon.
