How did the universe come about? This question does not cease to excite all those people who at least once looked into the night sky, sparkling with stars.
Since time immemorial, people have come up with different explanations. The easiest way was to explain the birth of the universe to Divine Providence. And although this did not explain where God came from, the theory was long considered the only true one.
But time passed, and the question of how the universe appeared, scientists decided to answer.
The first scientific theory was The Big Bang Theory. Studying the starry sky, the Hubble astronomer in 1929 concluded that the galaxies he observed were getting farther apart. He concluded that the universe is expanding. Arguing further, Hubble concluded that approximately 13.5 billion. years ago, the size of the universe was comparable to zero, and its density and temperature - 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. This myth echoes the theory of the Big Bang, but, like the “divine” stories about the birth of the cosmos, 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 clot. As a result of the explosion, time and gravity were divided, the Universe began to expand and be filled with particles falling into it with the help of gravity and motion. Facing, scattering, 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 “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 this way: in the available cosmic world, invisible and imperceptible subtlest ultra-sensitive membranes constantly exist. Interacting during the collision, they form many microparticles. Once, colliding and drawing together 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 explaining how the universe came about. According to her, Cosmos is nothing more than another surge that occurred in an ongoing process. When the surge ends, the Earth will come to an end with its environment.
According to the scientist A.D. Linde, the Universe was born as a result of the interaction of electric forces, gradually passing 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 andron collider partially confirms their assumptions.
Which theory is correct? Nobody knows for sure yet. Perhaps the time will come, and we will reliably establish how the universe appeared. In the meantime, we have time to dream, invent, explore, analyze.
