The big bang was not "discovered" but contrived by mathematicians following the proposal of a Belgian Roman Catholic priest and astronomer, George Lemaitre, for the origin of the universe from a "primeval atom" or "Cosmic Egg exploding at the moment of the creation." The theory defies physics principles and is unrealistic, needing most of the matter in the universe to be invisible (not even dark) and a mysterious 'dark' energy.
