The origin of the Universe, the world around us, human civilization - all these issues worried a person, starting from ancient times. Philosophers, theologians, scientists, and ordinary citizens have put forward many hypotheses about the origin of our galaxy, but none of them can still be considered scientifically proven.
For many centuries, until the emergence of A. Einstein's famous general theory of relativity , it was believed that our Universe is static, homogeneous, infinite in spatial and temporal dimensions. In the most general form, such a model was described by I. Kant, which was based on the laws of mechanics by I. Newton.
For Kant, the infinity of the Universe stems from the fact that it is the absence of spatial and temporal limitations that can lead to the origin of the infinite set of accidents that a person observes in everyday life. It was as a result of these accidents that, for example, the formation of the biological diversity of the Earth became possible. However, by the beginning of the 20th century, so many contradictions had already been found in this model that it ceased to satisfy even the adamant supporters of I. Kant. New theories of the origin of the universe began to appear .
The most comprehensive approach to this issue was the German scientist A. Einstein. The origin of the universe, the scientific meaning of this phenomenon, has become one of the main impetus for the creation of his famous theory of relativity. Based on its position, we can conclude that the Universe is not static, but is constantly expanding, and its expansion is slowed down as it expands. By analogy with the well-known chemical phenomenon, this hypothesis is called the Big Bang.
The origin of the Universe, its chronological beginning, has become possible to calculate using data on the motion of stars and other celestial bodies. It turned out that our Universe has existed for several billion years, while some scientists claim that its age is more than 20 billion years.
This model of the origin of the Universe had one significant flaw - the Big Bang itself, since it was unclear how energy could arise from almost nothing. An opinion was suggested about the existence of the Great Designer, or God, with which a significant part of scientists could not accept. The origin of the universe began to be associated with the movement of plasma and pulsating processes, and Thomas Gold and Fred Hoyle generally returned to the idea that the Galaxy was static.
At the same time, in recent decades, several major discoveries have been made that directly confirm the Big Bang theory. Moreover, scientists were able to prove that space and time originate in this phenomenon as well as energy with matter. Scientists can describe the events that happened with our universe, starting from 10 ^ -23 seconds after its inception.
The final touch in the proof of the Big Bang theory should be research in the Large Hadron Collider, which should result in evidence of the possibility of the transition of infinitesimal density, pressure and temperature to energy and matter.
