How did the Universe come about? This question never ceases to excite all those people who at least once looked at the night sky sparkling with stars.
From time immemorial, people have come up with different explanations. The easiest way was to explain the birth of the Universe by Divine Providence. And although this did not explain in any way where God came from, the theory was considered the only true one for a long time.
But time passed, and scientists decided to answer the question of how the Universe appeared.
The first scientific theory was the Big Bang Theory. Studying the starry sky, the astronomer Hubble in 1929 concluded that the galaxies he observed were getting further and further apart. He concluded that the universe is expanding. Reasoning further, Hubble came to the conclusion that approximately 13.5 billion. years ago, the dimensions of the universe were comparable to zero, and its density and temperature were comparable to infinity. There was a Big Bang, as a result of which time and the Universe began to expand. This theory finds its adherents today.
Some peoples have myths that the Universe appeared from a destroyed cosmic egg, which was the beginning of everything. Thisthe myth echoes the Big Bang theory, but, like the "divine" stories about the birth of the cosmos, it does not explain in any way who and when created this Cosmic Egg.
The Big Bang Theory has another explanation. According to some scientists, earlier matter, energy and time were a homogeneous, very dense bunch. As a result of the explosion, time and gravity were separated, the Universe began to expand and be filled with particles falling into it with the help of gravity and movement. Colliding, flying apart, hitting, these particles generated neutrons and protons. They did not change their essence for some time, but when the temperature of the Universe began to drop, elementary particles began to “stick together” and form chemical elements: lithium, helium, hydrogen.
However, a number of scientists have appeared who are not satisfied with the concept of an "expanding Universe". They came up with and almost proved a new theory. She denies the Big Bang.
To the question of how the Universe appeared, they answer as follows: in the existing cosmic world there are always invisible and imperceptible thinnest supersensitive membranes. Interacting in the process of collision, they form many microparticles. Once, colliding and approaching as close as possible, these membranes closed and formed our Universe.
But even this theory does not suit all astronomers and historians. There is another interesting hypothesis that explains how the Universe appeared. According to her, the Cosmos is nothing but another surge that has occurred in a constantly ongoing process. When the surge ends, the end will come for the Earth with itsenvironment.
According to the scientist A. D. Linde, the Universe was born as a result of the interaction of electrical forces, gradually passing through several phase transitions. He and some other scientists are sure that the Universe is the result of the interaction of light (photons) and heavy (bosons) elements. It seems that the hadron collider partially confirms their assumptions.
Which theory is correct? So far, no one knows for sure. Perhaps the time will come when we will reliably establish how the Universe came into being. In the meantime, we have time to dream, invent, explore, analyze.
