In 1929 Hubble discovered a correlation between distance and recession velocity — now known as Hubble's law.

This fact is now known as Hubble's law, though the numerical factor Hubble found relating recessional velocity and distance was off by a factor of ten, due to not knowing at the time about different types of Cepheid variables.

Hubble is generally mistakenly known for Lemaître's law or " Hubble's law " which was discovered by Georges Lemaître.

Using the data collected by Vesto Slipher and his ( Hubble's ) assistant Milton Humason ( a former mule-driver and janitor ), Hubble and Humason found a direct relationship between a galaxy's distance and its relative speed away from the solar system.

The primary source of verification of this expansion was provided by Edwin Hubble who demonstrated that all galaxies and distant astronomical objects were moving away from us (" Hubble's law ") as predicted by a universal expansion.

Subsequently, Edwin Hubble discovered an approximate relationship between the redshifts of such " nebulae " ( now known to be galaxies in their own right ) and the distances to them with the formulation of his eponymous Hubble's law.

Later observations ( by Hubble himself, among others ) showed Hubble's belief to be correct and the S0 class was included in the definitive exposition of the Hubble sequence by Allan Sandage.

The star spectral classification and discovery of the main sequence, Hubble's law and the Hubble sequence were all made with spectrographs that used photographic paper.

In 1929, Hubble and Milton L. Humason formulated what is now known as Hubble's Law by combining Cepheid distances to several galaxies with Vesto Slipher's measurements of the speed at which those galaxies recede from us.

He was also the first to derive what is now known as the Hubble's law and made the first estimation of what is now called the Hubble constant which he published in 1927, two years before Hubble's article.

Another scaling jump of 10 < sup > 9 </ sup > was required to extrapolate to galactic conditions, and a third jump of 10 < sup > 9 </ sup > was required to extrapolate to the Hubble's law # Hubble length | Hubble distance.

* April-Abbé Georges Lemaître publishes in the Annales de la Société Scientifique de Bruxelles " Un Univers homogène de masse constante et de rayon croissant rendant compte de la vitesse radiale des nébuleuses extra-galactiques " proposing the theory of the expansion of the Universe, deriving what will become known as Hubble's law, making the first estimation of what will become called the Hubble constant, and proposing what becomes known as the Big Bang theory of the origin of the Universe, which he calls his ' hypothesis of the primeval atom '.

Owen repairs Hubble's communicator and sends out a message to Hubble about how much he cares for him and the Greater Dane gets it.

* Edwin Hubble publishes his discovery that the speed at which galaxies recede positively correlates with their distance, which becomes known as Hubble's law, the basis for understanding that the universe is expanding.

* 1929 – Edwin Hubble: Hubble's law of the expanding universe

This redshift-distance correlation, nowadays termed Hubble's law, was formulated by Hubble and Humason in 1929 and became the basis for the modern model of the expanding universe.
