Co-Moving Coordinates Cannot Maintain Their Co-Moving Status in the Spatially Non-Flat Cosmological Models

Authors: Kenneth Sandale

It is thought that consideration of the General Relativity force law demonstrates that particles will retain their stationary status in the standard cosmological models. However this argument neglects the effects of pressure-dependent gravitational forces. When these forces are correctly included, what actually happens is that in spatially non-flat universes particles do not really remain co-moving, and indeed develop motion that is not consistent with the very symmetry condition these models were designed to manifest.
