Mapping the local cosmic web: Dark matter map reveals hidden bridges between galaxies

A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map, developed using machine learning by an international team including a Penn State astrophysicist, could enable studies about the nature of dark matter as well as about the history and future of our local universe.

Good.

Because dark matrer is only loosely attached to galaxies this makes sense. It’s also useful for defining bubble walls in galaxy formation, galaxies formed preferentially where four bubble walls met. Filaments are where three bubble walls meet.

Another nail in the coffin for MOND, not that another nail is needed.
