The Hubble Law is explained by the ______

Solution

the law was first derived from the general relativity equations by Georges Lemaître in a 1927 article where he proposed the expansion of the universe and suggested an estimated value of the rate of expansion, now called the Hubble constant.

Hubble\'s law is considered the first observational basis for the expansion of the universe and today serves as one of the pieces of evidence most often cited in support of the Big Bang mode

The law is often expressed by the equation v = H₀D, with H₀ the constant of proportionality (Hubble constant) between the \"proper distance\" D to a galaxy
