WebThis diagram shows several stages in a computer simulation of a collision between two galaxies. What happens? 1.Two spiral galaxies merge to become an elliptical galaxy surrounded by debris. 2. Two galaxies collide, sending their stars flying off into space while their centers merge to become a supermassive black hole. 3.
