GENERAL KNOWLEDGE

Detailed explanation-1: -This startling idea first appeared in scientific form in 1931, in a paper by Georges Lemaître, a Belgian cosmologist and Catholic priest. The theory, accepted by nearly all astronomers today, was a radical departure from scientific orthodoxy in the 1930s.

Detailed explanation-2: -In 1927, the Belgian Catholic priest Georges Lemaitre proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law. He based his theory on the work of Einstein and De Sitter, and independently derived Friedmann’s equations for an expanding universe.

Detailed explanation-3: -Few people took notice of Lemaître’s conclusions, but one person who did was Einstein himself, who told him: “Your calculations are correct, but your grasp of physics is abominable.”
