Google Doodle today is celebrating the 124th birthday of Georges Lemaitre, the Belgian astronomer who was the first to come up with the theory that universe is constantly expanding. Lemaitre today is widely known as the one to also propose the “Big Bang theory”, which suggests that the universe formulated by a huge explosion of a super-atom.
Born on July 17, 1894, Lemaitre went to study civil engineering at the Catholic University of Leuven at the age of 17. He put his studies on hold to serve in the Belgian army as an artillery officer in the first World War. However, after the war, he resumed his study in mathematics and physics, and took up a job as a part-time lecturer at the Catholic University of Leuven.
Lemaitre first became popular after publishing his report, which stated that the universe was in a constant state of expansion. He was the first to derive what is now known as Hubble’s law and made the first estimation of what is now called the Hubble constant – a unit of measurement that denotes the rate at which the universe is expanding. This theory was published by Edwin Hubble, two years after Lemaitre’s article.

Initially, Lemaitre’s theory was also dismissed by Albert Einstein stating that the application of physics was wrong. However, two years later, Einstein accepted the calculations to be correct. Moving forward, Lemaitre continued his work on the big bang theory and published more reports with more details about his learning. He was elected as a member of the Pontifical Academy of Sciences, where he went on to become the president in 1960. He died in 1966, shortly after having learned of the discovery of cosmic microwave background radiation.
