Hi Cosvis;

Good question, where is the antimatter?

Physicist, who believe in the big bang, now have an asymmetrical big bang to account for it. For every particle of matter that made it through a billion particles of matter and antimatter were annihilated.
Thus destroying CPT symmetry.

Paul Dirac, the one who theorized about antimatter thought it was out there in our universe, in another section yet, to be discovered. When there was virtually no evidence for this, he gave up on that theory. Now we know that only a small portion of our universe is observable because of spatial expansion, so Dirac may have been correct.

I do not like an asymmetrical universe idea, and so I thought maybe a parallel antimatter universe. In the lab when they "create" antimatter, and it goes through a verticle magnetic field, matter goes in one direction and antimatter goes in the opposite direction.

What are your thoughts Cosvis, or any other toequesters thoughts on this matter or should I say antimatter.

Best to you,

Pat
