What is Hubble Constant?

     We know that universe is expanding and now Hubble's law serve as one of the pieces of evidence most often in support of the Big Bang model of expansion of the Universe. Although widely attributed to Edwin Hubble, the law was first derived from the general relativity equations by Georges Lemaitre 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.
