The Riemann Hypothesis as Physical Law: Geometric Origin of the Proton Mass, Electric Charge, and Hadronic Structure from Kim's Isotropic Number

This work completes the KIT framework by deriving the proton-to-electron mass ratio and quark charges from the isotropic number. The N=3 hexagonal vertex of the KIT potential reproduces the proton mass ratio with zero free parameters and explains electric charge as a geometric phase imbalance. The argument establishes the Riemann Hypothesis as physically necessary: if any zero departs from Re(s)=1/2, atomic structure, fermion statistics, hadronic stability, charge quantisation, and superconductivity all fail. This preprint positions the Riemann Hypothesis as a fundamental physical law underpinning matter and the universe.
