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.

Don’t colliding galaxies mostly not actually touch? I thought there’s so much space between everything it’s almost entirely gravitational interactions. I’d assume almost no huge annihilation events from that, or extremely low frequency.
The stars and planets, yes, but there is a lot of very diffuse gas that does collide
