Edwin HubbleIn existographies, Edwin Hubble (1889-1953) (IQ:170|#316) [RGM:85|1,500+] (Cropper 30:3|NP) (Murray 4000:12|A) was an American astronomer, noted for []

In 1922, Alexander Friedman, using general relativity equations, published a set of equations, aka Friedmann equations, showing that the universe might expand, and presenting the expansion speed if this was the case.

In 1927, Georges Lemaitre proposed the expansion of the universe and suggested an estimated value of the rate of expansion; on this he conjectured (1931) that an expanding universe could be traced back in time to an originating “single point” (see: big bang).

In 1929, Hubble calculated the recession velocity of objects far away from our universe from their redshifts, and therein showed that the universe is expanding; the concluding point of which is known known as Hubble’s law.
