galaxy-rotation-curves

The EntropicGravity-Py library implements a high-performance N-Body simulation engine that replaces the standard Newtonian potential with Erik Verlinde's Entropic Force model. The goal is to audit whether the observed "mass discrepancies" in galaxies can be naturally explained by the thermodynamics of spacetime info-dynamics.
