Then Georges Lemaître, in a 1927 article, independently derived that the universe might be expanding, observed the proportionality between recessional velocity of and distance to distant bodies, and suggested an estimated value of the proportionality constant, which when corrected by Hubble became known as the Hubble constant.
There he proposed that the Universe is expanding, and suggested a value for the rate of expansion, now called the Hubble constant.
