Did you know that the Big Bang theory was first proposed by the Belgian priest and physicist Georges Lemaître?
His hypothesis of the primeval atom aims to explain the origin of the Universe and was the basis of the origin of the Big Bang. This cosmological model is used by scientists to describe the origin and evolution of the Universe. As the originator of the model, Georges Lemaître described the expansion of the Universe in broad terms.
In general, the term "Big Bang" is associated with all the theories describing our Universe as the result of a rapid expansion consistent with an explosion and consistent with the warm period that our Universe was experiencing at that time, several billion years ago.
A crater on the Moon bears his name.
