This report presents a Diffusion Gravity model for the MOdified Newtonian Dynamics (MOND) “standard” interpolating function through geometry of the Poisson equation of gravity, wherein we hypothesize additional gravity due to near-field gravity effects proximate to a star, i.e., between the star and its Lagrange point L1. That is, at the very large mass ratios (~10 11 ) and distance ratios (~10 20 ) of galaxies to stars, the L1 is very near the orbiting star. And at very large mass ratio’s of ~10 11 , resultant extreme asymmetry of the gravitational field gradient around the L1 point generates a near-field gravity potential ф NF , analogous to the near-field of electromagnetism (EM), adding to the total gravitational acceleration between the star and its galaxy. This model uses the Dirac Large Numbers Hypothesis to suggest an asymmetric Newtonian force law F=GMm/r 1 r 2 and near-field methods of EM to present a causal explanation for the constant velocity of stars within galaxies.
