Superfluid Dark Matter

Superfluid Dark Matter unifies MOND's galactic successes with particle dark matter's large-scale behavior, reproducing galactic rotation curves with 98% accuracy using zero extra parameters on those scales. Proposed by Justin Khoury in 2015 at the University of Pennsylvania, the model introduces three additional free parameters beyond standard CDM overall. While it outperforms #9 Emergent Gravity by delivering concrete, falsifiable predictions for dwarf galaxy core radii, critics argue it stiches two unsolved problems together rather than solving either.
