What Happens When Stars Collide?

What happens when bigger things smash into each other? Does that ever happen? Has it happened to our son? These are the kind of questions that keep me up at night. I think all stellar objects are beautiful, even the ones that mightnt inevitably come for us. But yetit, it is pretty interesting. There are so many stars out there in the galaxy, in the universe, that eventually some of em might run into each other,. They might crash into each other. Yet, turns out to be quite interesting. In some parts of the universe, stellar collisions are quite common, and in other places they are very rare.
