Explanation:
Detailed explanation-1: -We now know that the objects that Hubble observed are galaxies, similar to our own Milky Way, and that there are billions of them in the observable Universe. Hubble’s discovery provided additional evidence for what was to become known as Big Bang theory, first proposed by Georges Lemaître in 1927.
Detailed explanation-2: -Hubble’s observation showed that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. This means that things that are farther away from Earth were moving away more rapidly. In other words, it can be said that the universe must be expanding. He declared his conclusion in 1929.
