It looks like there are a lot of planets around a lot of stars.

And while I've read that galaxy mergers rarely have actual star collisions, I've never seen an estimate of how destructive they are to planets. Not via collisions, but near misses tossing them out of their (assumed) stable orbits.

I'd speculate that galaxy mergers could destroy life on a lot of planets. I wonder what the simulations tell us?
