Abstract
The equations of cosmological evolution are derived based on a new quasiclassical theory of gravity, which describes the effect of hidden mass or “dark matter.” The dynamic equations correspond to classical mechanics and are Eulerian equations for a dustlike medium. It is shown that taking into account the hidden mass effect leads to Friedmann’s equations for the scale factor of the medium, similar to the equations in general relativity. A comparative analysis of the evolution equations in general relativity and in the new theory is carried out. Based on a qualitative analysis of the Friedmann equations, some possible scenarios of cyclic cosmological evolution are considered, describing all its main stages, including the first and second inflationary stages with an intermediate stage of Friedman expansion.
期刊介绍：
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
