The Google 'doodle' depicts Belgian priest and astronomer Fr Georges Lemaître
Google’s “doodle” for Tuesday, July 18 celebrates the 124th birthday of the Belgian priest who formulated the Big Bang theory.
Fr Georges Lemaître was professor of physics at the Catholic University of Leuven and proposed a theory that said the universe was constantly expanding from a single first point. He named this the “hypothesis of the primeval atom”, or the “Cosmic Egg”.
He also proposed what later become known as “Hubble’s law” and “Hubble’s constant” two years before Edwin Hubble.
