The term Big Bang or Big Bang theory as it is also known, is one of the most popular and promoted theories within science, since it is responsible for explaining the origin of the universe and defends the fact that it was the product of a great shock. The origin of the term Big Bang is credited to the British-born astronomer Fred Hoyle, it is important to know that this was the product of the intention of said astronomer to name this theory in a pejorative way, with which he had no affinity. In addition to this, Hoyle is also responsible for the steady state theory. The theory itself indicates that the universe had its origin approximately 13.8 billion years ago, which expanded thanks to the explosion in question.
According to the theory, after the expansion the universe began a cooling process and it was there that the formation of the first subatomic particles took place and later, the atoms.
All those things that can be seen are made up of atoms and all of them are so tiny that they are impossible to perceive for the human eye. But before such atoms existed and matter could form there was nothing at all, such a situation being something that is somewhat difficult to imagine.
According to the Big Bang theory, there was a great explosion, which was the one that gave rise to the appearance of matter. It should be noted that there is a key fact that proves this idea, this was the expansion of the universe. According to many experts in astronomy, if there is a constant expansion of the universe, the movement that occurred must have started at some point. In other words, if the galaxies are moving away from each other, this means that there was a time when they were very close. The distance between the galaxiesit was such that they were all fused. Which implies that all the matter and space that was part of the universe were united at one point. Astronomers call this point "the initial singularity." At that moment was when the great explosion, known as the Big Bang, occurred.
