• The origin of the universe lies in the basics of Big Bang theory. According to this theory, about 1380 crore (13.8 billion) years ago, all matter and energy in the universe were focused into a zone smaller than an atom. The phenomena such as cosmic microwave background, the existence of light elements in abundance, the large-scale structure, and the Hubble’s Law are explained on the basis of big bang theory.Measurements regarding the expansion rate of the universe posit the big bang to have happened 13.8 billion years ago and so, this is accepted as the age of our universe.
