Origin of the universe is explained by the Big Bang theory. According to this theory, the universe started from an unimaginably tiny “dot”.This tiny structure is believed to have been infinitely hot and dense, and began expanding like a balloon after a supposed massive blast known popularly as the “big bang”. This theory was proposed in 1931 by Abbe Lemaitre, a Belgian priest, Astronomer and Professor of Physics at the Catholic university of Leuven. Although the reason for the blast remains unknown, it is widely believed that ever since the huge blast, the universe has been gradually and continuously expanding, and it has cooled down, leading to the formation of various atoms which have combined in different ways to form the stars and galaxies of today’s universe.Darwin and Lamarck postulated the theories of evolution which explain the process of evolution of life on earth.
