Abstract: The galaxies are generating a large amount of energy which in turn is increasing the angular momentum of the galaxies. We, in this paper assume that the total energy of a galaxy is proportional to the angular momentum of the galaxy and thereby derive the famous Hubble law of expansion of the universe. We also show the reason why some of the galaxies are receding away and the others like the Milky Way and the Andromeda galaxies are approaching towards each other. And ultimately we can explain the origin of the cosmological constant in the General Theory of Relativity of Einstein, which can be used to explain the accelerated expansion of the universe without assuming the existence of dark energy and dark matter Keywords: Gravitation, Red shift, Galaxy, Distance Modulus, Cosmology
