George Lemaitre


George Lemaitre was born in Charleroi, Belgium. When he was a young man, he was interested in science and theology. Wanting to pursue his scientific dream, Lemaitre went to America and got a Ph.D. at the Massachusetts Institute of Technology (MIT). In 1925, he became a professor at the Catholic University of Louvain. Continuing his science career, he wrote a paper explaining why the universe is expanding. Edwin hubble with his giant telescope, was able to observe galaxies beyond the Milky Way. Using Hubble's observation for his theory, Lemaitre was able to convince many astronomers that the universe was expanding.


Lemaitre's idea of how the universe was created, was that in the beginning of time, since the universe expands slowly, everything was compacted into an extremely dense mass. It was a singularity, or in Lemaitre's terms, the "primeval atom", which blew up and formed the universe that still expands today. The idea of the universe forming like that was called the Big Bang Theory.
