What Do You Think Happens When Stars Collide?

We asked people on the internet, what do you think happens when stars collide? And as usual, i'm grateful to our internet volunteers for answering random physics questions. If it sounds fun to you to get four random physics questions in your in box that you have to answer without any preparation, please just rite us and email to questions at daniel and horhay dot com. What do you think? What do you see in your head when you imagine two stars colliding?
