Colliding with andromeda won’t do anything. Galaxies are almost all empty space.
What if some alien civilization is watching the whole thing and taking bets
If they live for billions of years, I’d imagine our human evolution has happened so quickly to them, that they wouldn’t even realize we were here.
Can’t it mess up our nice solar system if other large objects come even remotely close?

Based on current calculations they predict a 50% chance that in a merged galaxy, the Solar System will be swept out three times farther from the galactic core than its current distance. They also predict a 12% chance that the Solar System will be ejected from the new galaxy sometime during the collision. Such an event would have no adverse effect on the system and the chances of any sort of disturbance to the Sun or planets themselves may be remote.
