- TL;DR Summary
- Galaxy collision separates dark matter from regular matter. Is this a compelling case for DM over alternate theories?
"... the gas between the galaxies collided, becoming turbulent and superheated. While both dark and normal matter are influenced by gravity, the normal matter also interacts via electromagnetism, which slowed it down during the collision.
Consequently, the dark matter moved ahead, decoupling from the normal matter."

This appears to be analogous to the Bullet Cluster.
Has this been verified, and is it strong evidence in favour of the DM theory? Do any other theories such as MOND explain the Bullet Cluster and now this find?
