On Tuesday, Google celebrated the 124th anniversary of the birth of the Belgian astronomer George Lemaitre with graffiti. Lemaitre is known as the Big Bang theory, which says that the universe originated from an atom, which he called the cosmic egg. He is also considered to be the first person to propose the theory that the universe is expanding.
He was born in 1894 and served in the Belgian Army during the First World War. He continued to study physics and mathematics and trained to become a pastor. He has studied physics and astronomy at some of the world’s most prestigious institutions, including Cambridge, Harvard and MIT.
In 1927, he published a theoretical paper – a paper from general relativity – that the universe is expanding. Two years later, this theory was confirmed by Edwin Hubble and will soon be called Hubble’s Law.
Albert Einstein initially rejected Lemaitre’s theory, but he later changed his mind. Hubble further studied the theory of the Big Bang, which led to a new branch of science called relative cosmology.
In 1934, Lemaitre won the Francqui Award, the highest scientific honor in Belgium – one of the proponents was Einstein. In 1953, he won the first Eddington Medal from the Royal Astronomical Society. Shortly after discovering the discovery of cosmic microwave background radiation, he died in 1966.
The graffiti website portrays Lemaitre. “In the ever-expanding universe he originally envisioned, the surrounding galaxies expanded as he said.”
