Gotta love the downvotes by the people that don't read the article. Tl;dr Dark matter model simulation can't explain bullet cluster, and MOND can. > Either way, the Bullet Cluster remained a stunningly unlikely event to happen in the theory of particle dark matter. It was, in contrast, easy to accommodate in theories of modified gravity, in which collisions with high relative velocity occur much more frequently.
