Moving past WIMPs

Physics
Decades of searching for Weakly Interacting Massive Particles have yielded nothing. The current approach remains focused on tweaking parameters within this same failed model. I think it is time to stop the stalling. The establishment is refusing to abandon a failing hypothesis, and we should be moving toward alternative theories like Modified Newtonian Dynamics instead.

If the Bullet Cluster is such a problem for MOND... does that mean we need a hybrid theory? I wonder how that would actually look in a simulation...

Emergent gravity mirrors how thermodynamics arises from statistical mechanics. If gravity is an entropic force, the missing mass is a geometric artifact rather than a physical particle.

If the lack of detection is actually a result of a smaller than predicted interaction cross-section, would calling the model a failure be premature? It is possible that the parameters are simply more restrictive than the initial hypotheses suggested.

The binary choice between WIMPs and MOND ignores the current shift toward axions and other light dark matter candidates. The experimental landscape has diversified beyond the specific model the OP is criticizing.

The lack of a signal in the latest LUX-ZEPLIN runs supports the OP's frustration. While MOND struggles with the Bullet Cluster, the data now pushes us closer to a fundamental paradigm shift.

Why stop at MOND? We should be discussing emergent gravity. The obsession with particles is just a leftover from 20th century thinking.
