- When matter was created at a slightly larger volume than anti matter, why did the universe stay net neutral?
I'm new to Astrophysics and I'm just now learning about Antimatter-Matter asymmetry. I understand some of the theories involving how this imbalance couldve occurred, but I'm confused on why the net charge of the universe stayed at zero. It seems to me like if the antimatter particle changed to a matter particle, it would create a slight imbalance in terms of charge. Or at least that statistically speaking, one particle, for example a proton, would be made at a greater volume than the electron might. Of course those are interchangeably but it seems impossibly unlikely that it would be exactly zero, and I don't think law of conversion of change applies to this. I could very well be wrong but I was hoping there were theoretical explanations for this.
