Homogeneous and Isotropic Charge Densities to Accelerate the Universe
Various theoretical obstacles are associated with a homogeneous and isotropic distribution of ``charge'' which is subject to a repulsive, long-range force. We show how these can be overcome, for all practical purposes, by the simple device of endowing the particle which carries the force with a small mass. The resulting situation may be relevant to a phase of cosmological acceleration which is triggered by the approach to masslessness of such a force carrier.
