DEVELOPING TENDENCIES OF PRESENTATIONS ON GALAXIES AND STARS EVOLUTION
Abstract
This article analyzes the scientific worldviews about the evolution of galaxies and stars. In addition to the usual stars, there are also many interesting objects in galaxies, star clusters, galaxy clusters and superclusters. Among them, we know red giants, white dwarfs, neutron stars, exploding stars called nova and supernova, and black holes with strong gravity, from which even light cannot escape. It turns out that in distant galaxies, the distance of which is determined by Hubble's law, the brightness of supernovae is lower than they should be. In other words, the distance to these galaxies calculated using the "standard candles" method turns out to be greater than the distance calculated based on the predetermined value of the Hubble parameter. This led to the conclusion that the universe is not only expanding, but expanding at an accelerating rate.
