The Radion Saturation Principle: One Field, Three Phenomena — Cosmological Bounce, Black Star Arrest, and Flavor Anomalies

Proposes the Radion Saturation Principle: the saturation of the radion field phi at rho_c = 7.4 rho_nuc is the common physical origin of three phenomena across twelve orders of magnitude in scale: (1) cosmological bounce at T_bounce ≈ T_QCD = 158 MeV, (2) black star collapse arrest producing M_max = 4.56 M☉ and mass gap in GWTC-4.0, and (3) LHCb flavor anomalies P'5 ≠ 0 at 3.2σ..
