I hadn't thought of that. But what we observe isn't happening right now our data is a couple million years old.
No I said that Protons and Positrons have the some charge. Positrons and electrons have opposing charges which is why they only need to get close make annihilation almost impossible to prevent due to the atrraction of the particles.
The thing is common-matter and anti-matter are formed in together and usually when things happen naturally they only exist for moments before they come back together which requires small distance that they be seperated by that means they would comes apart then quickly come together again. The early universe was very crowded so it wasn't 'if' particle would interact during thier brief time in existance but to what degree. It is very possible for there to be anit-matter galaxies, we wouldn't be able to see them because they would use anti-photons instead of common-photons to emit light which would mutually destruct upon entering our galaxy.
For the charges question I'll use the anolgy of an atom. For every proton you need an electron to balance this. So in a way charges grow a bit. For range that is beyond me.
Annihilation radiation?
Like I said before common-Matter and Antimatter should be equal because they form together you can not have one without the other. It is a great mystery in science why they would be an imbalance. My theory tries to address just that.
