Quick Answer
Georges Lemaître first proposed an expanding universe in 1927. He linked the idea to the redshift of distant galaxies.
The Full Story
Georges Lemaître, a Belgian priest and physicist, published a paper in 1927 describing a universe that is expanding. He combined Einstein’s general relativity with observational data on galaxy redshifts to argue that more distant galaxies recede faster. His work came before Edwin Hubble’s better-known 1929 paper on the distance-speed relationship. Lemaître’s idea became central to modern cosmology and the Big Bang model.
