Which scientist provided the theoretical framework, utilizing General Relativity, that predicted the distance-velocity relationship observed by Hubble?

Answer

Georges Lemaître

While Edwin Hubble provided the definitive observational proof for the expanding universe in 1929, the theoretical groundwork for such a relationship had already been established. Georges Lemaître, two years prior, had used Albert Einstein’s equations derived from General Relativity to theoretically predict that the universe must be expanding, leading to a linear relationship between distance and recessional velocity. Hubble’s empirical compilation of distances and Vesto Slipher’s redshift data validated Lemaître’s theoretical model, making the expansion of the universe the primary observational pillar supporting the Big Bang Theory. This highlights a frequent pattern in science where theorists propose frameworks later confirmed by meticulous observers.
