Simulation of Two Galaxy Clusters Colliding

About this video
Duration: 12 seconds

Simulation of two galaxy clusters colliding. As the two clusters smash together, the dark matter falls to the center of the combined cluster and then back out. The dark matter moves outward, it begins to slow down under the pull of gravity and piles up, forming a "ring" of concentrated dark matter.
