What is Big Bang

The term Big Bang or Big Bang theory as it is also known, is one of the most popular and disseminated theories within science, as 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 attributed to the British astronomer Fred Hoyle It is important to know that this was the product of the astronomer’s intention to refer to this theory as pejorative, with which he had no affinity. In addition, 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 and, later, the atoms took place.

All these things that can be seen are made of atoms and they are all so tiny that they are impossible to be perceived by the human eye. But before these atoms existed and matter could form, there was absolutely nothing, such a situation being somewhat difficult to imagine.

According to the Big Bang theory, there was a great explosion, which was the one that gave rise to the emergence of matter. It should be noted that there is a fundamental fact that proves this idea, which is the expansion of the universe. According to many astronomy experts, if there is a constant expansion of the universe, the movement that took place must have started at some point.

In other words, if galaxies are moving away from each other, that means there was a time when they were very close together. The distance between the galaxies was such that they were all merged. Which implies that all matter and space that was part of the universe were joined at one point. Astronomers call this point the “initial singularity.” It was at this moment that the great explosion, known as the Big Bang, took place.
