Prediction of the Expansion of the Universe made by Alexander Friedmann and the Effect of Particle Creation in Cosmology
arXiv:2403.01555 · doi:10.3390/universe10020084
Abstract
This review devoted to the centenary of Alexander Friedmann's prediction of the Universe expansion presents the results obtained by him in 1922 and 1924 and the sketch of their further developments. Special attention is paid to the role of mathematics which enabled Friedmann to perform a radical departure from the conventional practice of considering our Universe as a static system. The effect of particle creation in expanding Universe is discussed concurrently with the earlier investigated phenomenon of pair creation from vacuum by external electric field. The numbers of scalar and spinor particles created at different stages of the Universe evolution are presented, and the possible role of the effect of creation of particles in the formation of relativistic plasma and cold dark matter after the inflationary period is noted. It is stressed that by introducing the concept of expanding Universe Friedmann made a contribution to understanding of the world around us compatible to those made by Ptolemy, Copernicus, and Newton in previous epochs.
