“…Under cosmic perspectives binding energy is an absolutely necessary quanity to be brought into the thermodynamical energy balance. As worked out in quantitative terms by Fahr & Heyl (2007a; this then leads to the following completed relation…”

“…k = 0) and Λ put equal to zero, the first Friedmann equation (see Equ. (13)) simplifies into the formṘ 2 =( 8πG/3)ρR 2 = Φ(R) and thus allows to identify a relevant cosmic gravitational potential Φ(R) in analogy to the one in Hamilton-Lagrangian dynamics (see Fahr & Heyl (2007a;). Therefore at the cosmic expansion permanently work has to be done by cosmic matter against an intermaterial force per mass which for ρ ∼ R −3 is given by…”

“…Requiring a universe where in every instant the positively valued vacuum energy is compensated by its gravitationally induced self-binding energy, then , in addition to the above thermodynamic requirement, one has to also fullfill the following relation (see Fahr & Heyl 2007a, 2007b) for a vanishing total vacuum energy…”

Especially it is then highly questionable whether under such conditions a constant vacuum energy density can at all be expected as an option.…”

In the present days of modern cosmology it is assumed that the main ingredient to cosmic energy presently is vacuum energy with an energy density ǫ vac that is constant over the cosmic evolution. In this paper here we show, however, that this assumption of constant vacuum energy density is unphysical, since it conflicts with the requirements of cosmic thermodynamics. We start from the total vacuum energy including the negatively valued gravitational binding energy and show that cosmic thermodynamics then requires that the cosmic vacuum energy density can only vary with cosmic scale R = R(t) according to ǫ vac ∼ R −ν with only two values of ν being allowed, namely ν 1 = 2 and ν 2 = 5/2. We then discuss these two remaining solutions and find, when requiring a universe with a constant total energy, that the only allowed power index is ν 1 = 2. We discuss the consequences of this scaling of ǫ vac and show the results for a cosmic scale evolution of a quasi-empty universe like the one that we are presently faced by.

The Cosmic Microwave Background (CMB) is taken today as reflecting the thermodynamical state of the universe at these early cosmic times. Based on this assumption and standard cosmological principles meanwhile many fundamental cosmological facts have been deduced from the CMB state which, however, to some surprise reveal that the universe should be dominated by dark energy and dark matter, while for its energy content the usual baryonic matter is nearly negligible. Thus the question which we want to raise in this article is, whether this standard interpretation of the CMB phenomenon is solid and unequivocal enough to support the standard cosmological claims. We shall show, however, that in many details the standard explanation is not straightforward, but allows for important alternatives which seriously should be looked at. Especially arguments for a vanishing cosmic curvature (k = 0) are shown to be weak, and, contrary to the usual claim, the light distance to the recombination horizon is in fact strongly model-biassed. We also show that the CMB dipole which is generally understood as a consequence of a peculiar motion by about 680 km/s with respect to rest system of the CMB can as well, and perhaps even better, be understood as indication of differerent cosmological expansion dynamics seen in an anisotropically expanding universe in different directions of the sky. We also discuss that the power amplitude (i.e. effective Planck temperature) in the dipolar CMB structure depends on wavelength even inverting the dipole maximum orientation in the Wien's branch. In addition unexpected properties of the lowest CMB multipoles could mean that we are at least partly seeing an unquantifyable foreground in the background. Only after its removal the CMB interpretation could at all then, but then on a completely new basis, become a subject of cosmological terms. At the end of this article we shall briefly discuss an alternative explanation of the CMB radiation which helps to better understand the mysterious cosmic photon-to-baryon ratio of about 10 9 .
