Because sometimes you need to see this stuff. Here are two galaxies that have actually collided. Galaxies are by far mostly empty space… stars are tiny nuggets only a few hundred thousand or maybe million miles wide, separated by distances measured in lightyears. So when galaxies collide, they go right through each other. But the gravitational influences can cause galaxies to be greatly distorted or just plain torn asunder.
