Question

Who proposed 'Big Bang hypothesis'?

• A. C. Darwin
• B. G. Lemaitre
• C. S. Miller
• D. S. Prusiner

Answer 1

The correct option is B G. Lemaitre

Georges Lamaitre was a Belgian priest, astronomer and a professor of physics. He is considered the father of the Big Bang theory. According to the theory, the expansion of the observable universe began with an explosion of a single particle at a definite point in time.
Earlier versions of the 'Big Bang theory' had the universe originating from a singularity, this has been replaced by the idea that the universe originated from literally nothing at all.
