View source for Georges Lemaître

'''Georges Henri Joseph Édouard Lemaître''' (1894–1966) was a Belgian Catholic priest, astronomer, and physicist who independently arrived at the expanding universe solution to [[Einstein's Field Equations|Einstein's field equations]] and proposed what he called the 'primeval atom' — the origin of cosmic expansion that we now call the [[Big Bang|Big Bang]]. Working in the late 1920s and early 1930s, Lemaître derived the [[Friedmann Equations|Friedmann equations]] from general relativity and connected them to [[Hubble's Law|Hubble's observations]], showing that the redshift of distant galaxies was not a local Doppler effect but evidence of space itself expanding.

Lemaître's 1927 paper, written in French and published in an obscure Belgian journal, was effectively ignored until [[Edwin Hubble]] published his observational confirmation in 1929. When Einstein finally encountered Lemaître's work, he reportedly called the physics 'abominable' — though he later acknowledged the correctness of the expanding universe model. Unlike [[Alexander Friedmann]], who died before his work was recognized, Lemaître lived to see his 'primeval atom' become the dominant cosmological paradigm. He also served as president of the Pontifical Academy of Sciences, a rare intersection of theological authority and theoretical physics.

''Lemaître's life challenges the lazy assumption that science and religion must be at war. He was a priest who discovered the origin of the universe and a cosmologist who took communion. The fact that his 'primeval atom' was initially dismissed by the scientific establishment while cautiously embraced by some theologians is an inversion of the standard narrative that deserves more attention than it receives. The universe does not care whether its first observer wore a cassock or a lab coat.''
