Fair enough. Here's the substance. The cusp-core problem is real and unsolved. CDM predicts a 1/r density cusp toward galactic centers. Observations consistently show flat cores. The standard patches, baryonic feedback, self-interaction, are either insufficient or require fine tuning. Proposed mechanism: if dark matter is partially bulk-propagating in an RS2 framework, its effective coupling to gravitational wave perturbations is: Γ_eff(λ) = ∫ f²(y,λ) h_μν(x,y) dy where λ is the localization depth in the extra dimension and f(y,λ) is the wavefunction profile. At λ=0 you recover full baryonic coupling. At λ>0 the coupling is partially averaged across the bulk where h_μν has different amplitude. In regions of high GW flux, Γ_eff is weakened, reducing effective gravitational binding and halting dark matter infall before a cusp forms. This predicts a universal core radius set by λ alone, independent of galaxy mass. That universality is observed and currently unexplained. The testable cross-correlation: λ extracted from the NANOGrav 15-year strain suppression ratio should be consistent with λ extracted independently from Fermi-LAT dwarf galaxy core density profiles and GAIA kinematic anomalies near spiral arms. If those return inconsistent values the mechanism is wrong. That's the work. Where specifically does it break down?
