An anisotropic cosmological model with expansion and rotation and the Bianchi type IX metric has been constructed within the framework of general relativity theory. The first inflation stage of the Universe filled with a scalar field and an anisotropic fluid is considered. The model describes the Friedman stage of cosmological evolution with subsequent transition to accelerated exponential expansion observed in the present epoch. The model has two rotating fluids: the anisotropic fluid and dust-like fluid. In the approach realized in the model, the anisotropic fluid describes the rotating dark energy.

Note: Dr. Bentovish (Bentwich) is seeking scientific collaboration and validation of this New ‘G-d’s Physics’ (Computational Unified Field Theory) Paradigm’s Empirical “Critical Predictions” involving precise Astronomical/Cosmological Measurements, as well as time-sensitive Accelerators validations. Twenty-first Century Theoretical Physics is at a state of crisis akin to pre-Einstein’s 1905 Relativistic “Paradigmatic Shift: its two primary “pillars”, Relativity Theory (RT) and Quantum Mechanics (QM) seem contradictory and up to 95% of all mass and energy in the universe is unaccounted for (termed: “dark-matter” and “dark-energy”); A New “Computational Unified Field Theory” (CUFT) discovered over the past eight years – also called: “G-d’s Physics’ Paradigm was shown to resolve this apparent RT-QM inconsistency and discard “dark-matter”, “dark-energy” as “superfluous” (i.e., non-existent)! This article delineates this New ‘G-d’s Physics’ Paradigm’s new “Atom”, e.g., basic “building-block” of the physical universe associated with its discovery of the singular (higherordered) “Universal Computational Principle” (UCP) which simultaneously computes every exhaustive spatial pixel in the universe at the incredible rate of “c2 /h”=1.36-50 sec! This New ‘G-d’s Physics’ Paradigm “Atom” is shown to challenge and negate some of the basic assumptions of RT’s & QM’s Old ‘Material-Causal’ Paradigm, including: the “Big-Bang” Model, Einstein’s Equations, the “Speed of Light Barrier” and opens new exciting possibilities including “time-reversal”, and a complete integration of “space”, “time”, “energy” and “mass” within a new exhaustive “Universal Computational Formula” (which integrates and transcends key components of RT & QM); The New ‘G-d’s Physics Paradigm reveals a new Purposeful Universe which possesses multiple possible “future/s” associated with the “Moral Choices” of Human-beings, and which is directed towards an ultimate “Perfected State” (Morally, Spiritually and Physically)!

Based on the Gravito-Electro-Magnetic (GEM) equations as another form (for low fields) of Einstein's Equations of General Relativity Theory (GRT) an equation is derived for the total energy density in the universe, including the gravitational fields, the contribution thereof is always negative and so it seems to represents the Dark Energy (DE).  When calculating the total energy of the universe from this equation, the result is near to zero because of negative contributions from gravitational fields, depending a little on the available parameters of the universe as e.g. it's baryonic mass. Thus the assumption is given a high amount of probability, that the total energy (mass) in the universe is really zero and very likely is always zero. This  would mean, that the universe developed from empty space-time or from nothing (may be by quantum fluctuations). Looking on the development it could be  that the average energy density is zero for each sufficient large part of the universe at any time, except for very local deviations (e.g. galaxies, black holes etc.). As a consequence the expansion of the universe is probably not retarded by gravity (thus the Friedmann equation and others do not apply). The expansion of the universe can be considered as driven by the pressure of a gas-like medium with positive masses as by intergalactic gas, dust, stars and galaxies. Conclusions are drawn as to the interpretation of the formation of voids in the universe, flat space etc.

We consider cosmological scenarios based on f(R, T) theories of gravity (R is the Ricci scalar and T is the trace of the energy–momentum tensor) and numerically reconstruct the function f(R, T) which is able to reproduce the same expansion history generated, in the standard General Relativity theory, by dark matter and holographic dark energy. We consider two special f(R, T) models: in the first instance, we investigate the modification R + 2f(T), i.e. the usual Einstein–Hilbert term plus a f(T) correction. In the second instance, we consider a f(R) + λT theory, i.e. a T correction to the renown f(R) theory of gravity.

Density Profiles

We investigate some models of compact objects in the general relativity theory with cosmological constant [Formula: see text], based on two density profiles, one of them attributed to Stewart and the other one to Durgapal and Bannerji, proposed in the literature to model “neutron stars”. For them, a nonlocal equation of state with cosmological constant is obtained as a consequence of the chosen metric. In another direction, we obtain a solution for configurations with null radial pressure. The first model (based on Stewart’s density profile) turned out to be the most interesting, since surprisingly it admits the presence of dark energy in the interior of the star, in the outermost layers, for a certain range of mass–radius ratio [Formula: see text]. This dark energy is independent of the cosmological constant, since it is a consequence of the tangential pressure of the fluid be sufficiently negative. Still in this case, for other values of [Formula: see text], all the energy conditions are satisfied. Another advantage of this model, as well as that based on the density profile of Durgapal and Bannerji, is the existence of intervals of [Formula: see text] compatible with physically acceptable models for [Formula: see text], [Formula: see text] and [Formula: see text], which also allowed us to analyze the influence of [Formula: see text] on the behavior of the fluid with respect to the energy conditions. The other configuration studied here, [Formula: see text], only allows solutions for [Formula: see text], in order to ensure a positive mass for the object and to satisfy all the energy conditions in a specific range of [Formula: see text].
