Google Doodle: Remembering cosmologist Georges Lemaitre: On this 17 July, Google paid tribute to Georges Lemaitre, the Belgian priest, cosmologist, and astronomer.

Lemaitre accurately estimated the numerical value that astronomers would come to call the Hubble constant, a unit of measurement that describes the universe's rate of expansion.

Today Google Doodle are celebrating the man who proposed the universe began from a single primordial atom, the "Cosmic Egg".

Lemaitre gave his lecture and theory, Albert Einstein stood up and said: "this is the most handsome and satisfying explanation of the universe that I have ever heard."He was elected a member of the Royal Academy of Sciences and Belgium Arts and the Pontifical Academy of Sciences".

In 1927 he became professor of astrophysics at the Catholic University of Leuven.


Born on July 17, 1894 in the Belgian city of Charleroi, Lemaitre wore many hats in his lifetime.

Georges Lemaitre started studying to be a civil engineering however his education was interrupted when he went to serve as an artillery officer in the Belgian army for the duration of World War I, at the end of which he received the Military Cross with palms.

Lemaitre is known to be a student at University of Cambridge, Harvard and Massachusetts Institute of Technology (MIT). Subsequently, he kept preparing to be a Catholic priest and got ordained in 1923.

Albert Einstein proposed Lemaitre to receive Belgium's highest scientific honor. Moving forward, Lemaitre continued his work on the big bang theory and published more reports with more details about his learning. He called it as the "hypothesis of the primeval atom" or the "Cosmic Egg". In 1953, he won the first Eddington Medal from the Royal Astronomical Society.

The Doodle shows Lemaitres at the center of a "constantly expanding universe" which he had first theorised in his works.
