Why do matter and antimatter annihilate? (bigthink.com)

From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate? There’s a quantum reason we simply can’t avoid.

I'm a smoothbrain, so I like to think about it as them simply canceling each other out. What I'm more curious about though, is why there's so much matter compared to antimatter.

annihilation results in a large energy release. so nothing is actually disappearing. changing form maybe. I'm guessing at the big bang matter/anti-matter went opposite directions and we just can't see that half. not speculating about symmetry. just a large amount of anti-matter beyond observational light-speed limits. speculation
