A step-by-step foundation for the differential character of the Universe's rotation is presented. First, invoking the concept of spacetime foam with spin, it is reasonable to assume that the very early Universe can be described by the Dirac equation. Second, it is shown using the Ehrenfest theorem that, from a classical point of view, the early Universe can be described by the Papapetrou equations. Third, it is stressed that our Universe can perform only rotational motion. It is shown based on the spin part of the Papapetrou equations that the Universe's rotation depends appreciably on the physical properties of a specific cosmological epoch. The rotational angular velocity is calculated for three basic cosmological epochs: the matter-dominated epoch, the transition period (from domination of matter to domination of vacuum), and the vacuum-dominated epoch.

“…In addition, the fact that these results can also depend on the presence of dark energy and its concentration, 16 on the rate of growth of baryonic matter perturbations 17 or on the rotation of the early Universe, 18 should not be excluded. However, perturbations in the primordial plasma not only stimulate the process of nucleosynthesis, 19 but also kill it, for example, through the growth of the perturbations of non-baryonic matter of the Universe 20 because of the oscillations of cosmic strings.…”

Abstract:We have studied the neutron-capture reactions 8 Li(n,) 9 Li and its role in the primordial nucleosynthesis. The n+ 8 Li 9 Li+ reaction has a significant astrophysical interest, because it includes into one of the variants of chain of primordial nucleosynthesis processes of the Universe and thermonuclear reactions in type II supernovae. Furthermore, we consider the 9 Be(p,) 10 B reaction in the astrophysical energy range in the modified potential cluster model with splitting of orbital states according to Young tableaux and, in some cases, with forbidden states. The reaction 9 Be(p,) 10 B plays an important role in primordial and stellar nucleosynthesis of light elements in the p shell. Hydrogen burning in secondgeneration stars occurs via the proton-proton (pp) chain and CNO cycle, with the 9 Be(p,) 10 B reaction serving as an intermediate link between these cycles. Furthermore, the possibility of describing available experimental data for the total reaction cross sections of neutron radiative capture on 10 Be at thermal and astrophysical energies has been shown. This reaction is a part of one of the variants of the chain of primordial nucleosynthesis of the Universe due to which the elements with a mass of A > 11-12 may be formed. The results in the field of study of thermonuclear proton capture reaction on 10 B at ultralow, i.e., astrophysical energies will be presented further.

J. Mod. Phys. E 21, 1250039 (2012); 22, 1350028 (2013); 22, 1350075 (2013); 23, 1430012 (2014). Astrophysical aspects of the reviewAs we know, light radioactive nuclei play an important role in many astrophysical environments. In addition, such parameter as cross section of the capture reactions as 2 a function of energy and reaction rates are very important for investigation of many astrophysical problems such as primordial nucleosynthesis of the Universe, main trends of stellar evolution, novae and super-novae explosions, X-ray bursts etc. The continued interest in the study of processes of radiative neutron capture on light nuclei at thermal (> 10 meV) and astrophysical (> 1 keV) energies is caused by several reasons. Firstly, this process plays a significant part in the study of many fundamental properties of nuclear reactions, and secondly, the data on the capture cross sections are widely used in a various applications of nuclear physics and nuclear astrophysics, for example, in the process of studying of...
