Abstract
In the recent years, a number of studies have been carried out to substantiate cosmological effects within the framework of the relational approach to the nature of space-time and physical interactions. It has been shown that the cosmological redshift and the cosmic microwave background can be a result of contributions from emitted but unabsorbed radiation. However, until now, Hubble’s law has not been entirely derived from the relational ideas themselves. In this paper, such a derivation is presented, and the Hubble parameter is calculated for the present epoch. To get this, the momentum contributions of emitted but unabsorbed radiation to the momentum of a distant astronomical object (a cluster of galaxies) are considered. It is shown that taking these contributions into account leads to the linear Hubble law.
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
