The Big Bang is a physical theory that describes how the universe expanded from a primordial state of high density and temperature. It was first proposed as a physical theory in 1931 by Roman Catholic priest and physicist Georges Lemaître when he suggested the universe emerged from a "primeval atom".
The common name has allowed for the beginnings of our universe to be too often depicted as a massive explosion similar to that of an epic supernova.
