The Hubble constant, also known as Hubble's law, is a statement about physical cosmology, which was first formulated in 1929 by Hubble and Milton Emerson after nearly a decade of observation, and is considered to be expanding. The first observational basis on the spatial paradigm is often cited as an important evidence in support of the big bang. With the introduction of Hubble's law, the concept of the expansion of the universe is gradually established.
