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.
