Reply to comment by mangalore-x_x in what exactly happens when 2 galaxies collide? by [deleted]
I don't know, man. I feel like stars and planets colliding would be pretty insane. That would not be some slow and gentle event. The moment shit starts colliding, at tens of thousands miles per hour, it would be catastrophic.

Which is the misconception.
There would be few collisions. Galaxies colliding is not two cars smashing together, for lack of a better image it is on astronomical scales more like two gases mixing.
On a time scale of millions to hundreds of millions of years. Same for stray stars getting ejected.
