Inflationary universe

In addition to the question of the origin of the universe, modern cosmologists face a number of other problems. So that the standard theory of the big bang could predict the distribution of matter that we observe, its initial state must be characterized by a very high degree of organization. The question immediately arises: how could such a structure be formed? The physicist A. Gut from the Massachusetts Institute of Technology proposed his version of the Big Bang theory, which explains the spontaneous emergence of this organization, eliminating the need to artificially introduce exact parameters into the equations describing the initial state of the Universe. His model was called the “inflationary universe.” Its Continue reading
