The Big Bang Catholic STEM Fair

This annual event is not only a way to provide an opportunity for our Catholic school students to showcase their talents in science, technology, engineering and math, but also to highlight the Catholic Church’s long history of supporting the sciences and note the many Catholic pioneers in the field.

George Lemaître (Father of the "Big Bang")

Georges Lemaître (17 July 1894 – 20 June 1966) was a Belgian Catholic Priest, astronomer and professor of physics at the Catholic University of Leuven. He proposed on theoretical grounds that the universe is expanding, which was observationally confirmed soon afterwards by Edwin Hubble. He was the first to derive what is now known as Hubble's law  which he published in 1927, two years before Hubble's article. Lemaître also proposed what became known as the Big Bang theory of the origin of the universe, which he called his "hypothesis of the primeval atom" or the "Cosmic Egg".
