The Google Doodle on Tuesday that marks Lemaitre's 124th birth anniversary depicts the cosmologist within the constantly expanding universe that he first envisioned, surrounded by galaxies expanding outward just as he said they would.
Lemaitre's 1927 paper theorising that the universe was expanding was soon substantiated by Edwin Hubble's observations, which were published in 1929.
Google doodle dedicated to Belgian astronomer Georges Lemaitre. His role as a priest and a scientist rarely intersected.
At a seminar in California, Einstein reportedly said of Lemaitre's theory: 'This is the most lovely and satisfactory explanation of creation to which I have ever listened'.
His first reference to the Big Bang theory was in an academic paper from 1931.
Lemaitre first became popular after publishing his report, which stated that the universe was in a constant state of expansion. He called this dense state as the "primaeval atom", which gave rise to space and time.
He died on 20 June 1966, shortly after having learned of the discovery of cosmic microwave background radiation, which provided further evidence for his own intuitions about the birth of the universe.
Lemaitre's work was widely recognised around the world, and are hugely influential until this day.
