The redshift in light coming from distant galaxies is proportional to their distance from earth.
The law was first formulated by Edwin Hubble in 1929 after nearly a decade of observations. It is considered the first observational basis for the Big Bang. Exerpt from Wikipedia. Information held under GNU Free Documentation License.
