Man that’s pretty wild to think about. If antimatter was created at the same time as matter in the same quantity and distribution, then why are we here. Why didn’t the entire universe essentially cancel itself out? Was there some factor that benefited regular matter or hindered antimatter? Is there some level of chaos on the atomic or subatomic scale that played in regular matter being the dominant? Has some crazy philosophical implications.
I mean if you just thought of all those questions on your own, that’s damned impressive. You just summarized one of the greatest mysteries in particle physics. Here’s a story about that exact question - what was the process that gave preference to creation of matter over antimatter?
The universe very nearly did cancel itself out entirely. That’s why it is as empty as it is. The matter you see is the slight surplus there wasn’t enough antimatter to annihilate. Why this surplus? It’s one of the great remaining problems.
I think there’s an extreme form of the anthropogenic principle we can apply here. Universes may pop into existence constantly and destabilize into nothing because their physical laws aren’t fine tuned for stability, or because they don’t have an uneven amount of anti/matter. Perhaps universes are part of some extra-cosmic superstructure that’s just frothing like mad. Some
bubbles last a little longer than others before they pop. We could be one of those. Perhaps the multiverse is a little bit of suds in some leviathan child’s bathtub.
Ok that makes sense.

You’re describing the matter-antimatter asymmetry problem
