Entanglement-Driven Cosmological Expansion (EDCE): Paper IX: Observational Evidence Global Validation - A Population-Wide Audit of Entropic Gravity in 175 SPARC Galaxies

The “Missing Mass” problem in galactic rotation curves is conventionally solved by invok- ing invisible Dark Matter halos, typically requiring at least two free parameters per galaxy (halo mass and concentration) to fit observations. In this paper, we present a global vali- dation of the Entropic Gravity framework, which posits that the “Dark” component is an emergent phenomenon arising from the thermodynamic response of spacetime to low accel- eration information density. Using the SPARC database (N = 175 galaxies), we apply the Entropic force law with zero free parameters, utilizing only the observed baryonic mass and a universal acceleration scale (a0 ≈1.2 ×10−10 m s−2). We find that the Entropic prediction…
