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

Big Big Bang Challenges

Upon careful consideration, the cosmological theory of the origin and structure of the universe begins to crack at the seams.

Take a look at the starry night sky. How did all these countless stars and planets come about? Most modern scientists are likely to answer this question by referring to one version of the Big Bang theory. In accordance with this theory, at first all the matter of the Universe was concentrated at one point and heated to a very high temperature. At some point in time, an explosion of terrifying force occurred. In an expanding cloud of superheated subatomic particles, atoms, stars, galaxies, planets gradually began to Continue reading

Big Bang Scenario

Like any scheme that claims to explain the data on the spectrum of microwave cosmic radiation, the chemical composition of pre-galactic matter and the hierarchy of the scales of cosmic structures, the standard model of the evolution of the Universe is based on a number of initial assumptions (about the properties of matter, space and time) that play the role of original conditions for the expansion of the world. One of the working hypotheses of this model is the assumption of uniformity and isotropy of the properties of the Universe throughout all stages of its evolution.

In addition, based on data on the spectrum of microwave radiation, it is natural to assume that in the Universe in the past there was a state of thermodynamic equilibrium between plasma and radiation, the temperature of which was high. Finally, Continue reading
