Dark matter affects some galaxies, but the rotation of others is completely explained by the observable matter. Why would one galaxy be influenced by its many worlds twins, but not another?

Sci-fi plot concept answer: because one galaxy is populated by sentient life, and the other isn’t.

Quarantine by Greg Egan explores this concept (the many-worlds theory, without the dark matter).
