Cosmology and Gravitostatics
  In gravitostatics, the minimally generalized Newtonian theory, the simplest cosmological model implies a cosmological redshift with acceleration parameter -1. If the gravitational potential satisfies a wave equation, the total mass density (visible plus dark) is one third of the critical density, in good agreement with observation. There is no horizon problem and no need to invoke dark energy.
