Pressure in dark source flux cosmology

Abstract [en]

A cosmological pressure concept is defined from virial equations for open systems undergoing Hubble expansion. A uniform dark source flux model is assumed, comprising non-relativistic baryonic and dark matter (‘dust’); relativistic radiation; and dark energy. The pressures thus derived are compared with corresponding pressures derived from the Friedmann equation in standard cosmology. The pressures are found to agree for non-relativistic matter and relativistic radiation, but differ for dark energy. The ‘exotic’ negative pressure of dark energy in standard cosmology is replaced by a more down-to-earth positive pressure in the present theory. The reason for this deviation is that the local energy conservation criterion, which is built into the field equation in general relativity, is replaced by a compelling consequence of Hubble’s law: the criterion for balanced expansion. In the choice between questionable energy conservation in an accelerating system on one hand, and the experimentally verified Hubble’s law on the other, the latter is chosen in the present analysis.
