Creation of Cosmic Matter Through the Action of the Primordial Cosmic Vacuum Energy

Abstract

H.J. Fahr and M.Heyl

We have shown in recent papers (see Fahr, 2023, Fahr and Heyl, 2023) that the original explosion of the universe cannot have had its origin in a mass singularity of relativistically superhot cosmic matter, since the associated extremely strong centripetal gravitational field would clearly have impeded the Big-Bang to happen. As we suggest instead, the so called paradigmatic "Big-Bang", if it at all ever happened, must rather be caused by something like a positively pressurized primordial cosmic vacuum, but not by a singularity-condensed cosmic matter. The question, however, then is, how a cosmic vacuum in physical terms has to be constituted that drives the initial explosion of the universe as expected into a Hubble – expansion, and, while doing so, in addition generates that amount of cosmic matter which in the present days of our universe evidently is all around us and thus needs to have its non-singular origin later in the evolution of the universe? As we do show here in this article, this requires a positively pressurized vacuum with pvac = pvac (εvac) ≥ 0 and a vacuum energy density εvac that, while performing thermodynamic work at the expansion of the universe, decreases with the increase of the scale R of the universe. This, however, is different to the well known ΛCDM -model with a constant vacuum energy density which is presently in favour. On the basis of the general energy conservation law we do formulate a relation here, that describes the condensation of quantized energy structures in form of elementary masses out of the energized vacuum. While the relative energy density of vacuum-condensed masses ρm/ρvac is permanently increasing with world time t, the energy density of the vacuum itself permanently decreases. In this paper we look for solutions which on the basis of these procedures just lead to the structures which evidently appear in our present-day universe. Not yet solved, though touched by us in this paper here, is the question whether or not the elementary abundances of the condensed cosmic matter under these conditions also would match the astrophysical observations.
