GR vs MOND - not competing theories, both emerge from 7D geometry.
New paper: Kaluza-Klein reduction splits into GR (metric) + MOND (scalar sector).
7D Einstein-Hilbert → Einstein's equations + AQUAL.
Prediction: lensing = dynamics. Testable.

Galaxy clusters break MOND. They need ~1.7× more mass than predicted - modified gravity's biggest problem.
New paper: the enhancement comes from geometry. Hot plasma activates extra coupling channels (3 vs. 1 in cold galaxies).
√3 = 1.73. Matches data: 1.69 ± 0.39.
Predicts zero hydrostatic bias - testable with X-ray + lensing.🔗 https://zenodo.org/records/17922206
