We compute the one loop photon contribution to the graviton self-energy on de Sitter background and use it to solve the linearized Einstein equation for a point mass. Our results show that a co-moving observer sees a logarithmic spatial running Newton’s constant. Equivalently a static observer reports a secular suppression of the Newtonian potential.
