Confronted with microwave background observations by WMAP and with consternating supernova locations in the magnitude-redshift diagram modern cosmology feels enforced to call for cosmic vacuum energy as a necessary cosmological ingredient. Most often this vacuum energy is associated with Einstein's cosmological constant or with so-called "dark energy". A positive value of describes an inflationary action on cosmic dynamics which in view of recent cosmological data appears as an absolute need. In this article, however, we question the hypothesis of a constant vacuum energy density since not justifiable on physical grounds. Instead we show that gravitational binding energy of cosmic matter, connected with ongoing structure formation during cosmic expansion, acts similar to vacuum energy, since it reduces the effective gravitating proper mass density. Thus one may be encouraged to believe that actions of cosmic vacuum energy and gravitational binding energy concerning their cosmological effects are closely related to each other, perhaps in some respects even have identical phenomenologies.Based on results presented in this article we propose that the generally wanted action of vacuum energy on cosmic spacetime dynamics inevitably leads to a decay of vacuum energy density. Connected with this decay is a decrease of cosmic binding energy and the generation of new effective gravitating mass in the universe. If this all is adequately taken into account by the energy-momentum tensor of the H.-J. Fahr · M. Sokaliwska ( ) Argelander GR field equations, one is then led to non-standard cosmologies which for the first time can guarantee the conservation of the total energy both in static and expanding universes.We describe the structuring of cosmic matter by a change in time of the 2-point correlation-function. We do show here that cosmic structure formation drives accelerated cosmic expansion and feigns the action of vacuum energy density.

“…Thus an action without any backreaction contains a conceptual error, that is, a misconception. That means, if empty space causes something to change in terms of spacegeometry, because it represents some energy that serves as a source of spacetime geometry, perhaps since space itself is energy-loaded, then with some evidence this vacuum-influenced spacegeometry should change the energy-loading of space (see [54][55][56]). There is, however, a direct hint that modern precision cosmology [1] does not respect this principle.…”

“…It, for instance, implies that a completely empty space does not accelerate its expansion but can stagnate and leave cosmic test photons without permanently increasing redshifts and that on the other hand a matter-filled universe with a vacuum energy density different from vac,0 leads to an effective value of Λ eff which now in general does not need to be constant. It nevertheless remains a hard problem to determine this function Λ eff for a matter-filled universe in which a matter-polarized vacuum (see [56]) different from the vacuum of the empty space prevails. In the following we briefly discuss general options one has to describe this vacuum.…”

By three independent hints it will be demonstrated that still at present there is a substantial lack of theoretical understanding of the CMB phenomenon. One point, as we show, is that at the phase of the recombination era one cannot assume complete thermodynamic equilibrium conditions but has to face both deviations in the velocity distributions of leptons and baryons from a Maxwell-Boltzmann distribution and automatically correlated deviations of photons from a Planck law. Another point is that at the conventional understanding of the CMB evolution in an expanding universe one has to face growing CMB temperatures with growing look-back times. We show, however, here that the expected CMB temperature increases would be prohibitive to star formation in galaxies at redshifts higher than z=2 where nevertheless the cosmologically most relevant supernovae have been observed. The third point in our present study has to do with the assumption of a constant vacuum energy density which is required by the present ΛCDM-cosmology. Our studies here rather lead to the conclusion that cosmic vacuum energy density scales with the inverse square of the cosmic expansion scale R=R(t). Thus we come to the conclusion that with the interpretation of the present-day high quality CMB data still needs to be considered carefully.

“…9), but this time we especially look for the transport equation of the density moment n = n(t) by multiplying the kinetic equation with 4πv 2 dv and integrating it over the whole velocity space, however, now including a term for particle creation from viscous energy generation. This then yields the following moment equation (18) where the term is thought to represent a possible particle production per unit volume and time due to matter creation from the energy going into pair-production collision processes. This latter term thus might be extracted from the energy dissipation term assuming that, as a maximum, the following particle creation rate could be expected to result from it (19) and thus leads to the following revised density moment equation (20) which expresses the fact that the particle production term will only become non-negligible, if thermal energies are growing up to the order of the rest mass energy of the particles, i.e.…”

“…Alternative ideas on cosmic matter creation have already in the past been discussed at several places in the literature as e.g. by Mach [9], Dehnen and Honl [10], Hoyle [11,12], Hoyle, Burbidge and Narlikar [13], Fahr [14], Fahr and Zoennchen [15], Fahr and Heyl [16,17], Fahr and Sokaliwska [18,19]. In the following part of the paper we shall, however, now study in more detail how much matter creation can especially be expected to originate from the process of viscous energy dissipation in thermal matter of a cosmic Hubble flow.…”

Cosmic Matter Creation from Viscous Energy Dissipation: A Resurrection of Fred Hoyle’s Dream

Fred Hoyle is known as creator of the so-called “steady state universe” which latter, although permanently expanding, does not change its state of matter, especially keeping its density constant. To achieve this virtue Hoyle introduced into the energy-momentum tensor of the GRT field equations a term derived from a so-called ad-hoc creation field astonishingly leading to field equations very similar to the ones already developed by Tolman when introducing energy sources connected with viscous dissipation forces acting upon dust-like cosmic matter [1]. In this article here we shall again study the action of viscous forces in cosmic baryonic matter and shall boil it down to volume viscosity contributions to the viscous stress tensor in a universe with a compressible Hubble flow. Assuming that by collisions of any kind the energy of the differential Hubble drift between two collision points of cosmic matter particles, seen in the non-inertial rest frames of moving particles, is randomized and converted into thermal energy, one can then show with the help of a kinetic transport equation that during the cosmic expansion permanently thermal energy is generated leading to the result that the matter temperature, instead of falling-off, is linearly increasing with the scale of the universe. This not only questions the standard use of the model of pressure-free, dust-like matter in the universe, but furthermore indicates the possibility of an asymptotic cosmic-ray-like matter state including the possibility of matter creation by pair production.
