Who defined the big bang theory?

Answer 1

The Big Bang Theory was first postulated by the Father Georges Henri Joseph Édouard Lemaître, a Catholic priest from Belgium; he was a physicist and astronomer.


Georges Lemaître, a Belgian physicist and Roman Catholic priest, who, in 1927, independently used Friedmann's equations to propose that the inferred recession of the spiral nebulae (per Edwin Hubble's discovery of 1924) was due to the expansion of the Universe, is considered the father of the Big Bang Theory. As such, the Jesuit priest Georges LeMaitre was credited with being the first to mathematically detail a cosmological study now known as the Big Bang.

However the consensus for modeling cosmology was agreed upon based on the work of four scientists: Alexander Friedmann, Georges Lemaître, Howard Percy Robertson, and Arthur Geoffrey Walker. Occasionally referred to as the FLRW, FRW, FL, or RW (e.g., a complete or partial combination of their last initials) Universe, it presents a metric used to explain Einstein's field equation of general relativity and thus became the foundation for the currently understood version of the standard 'Big Bang Theory'.

Note: While the Friedmann Theory preceded the Big Bang Theory, the developed equations were fundamental to establishing a foundation for the Big Bang Theory. Alexander Alexandrovich Friedmann is best known for his pioneering theory that the universe was expanding, governed by a set of equations he developed from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time. From these equations he postulated three Friedmann models describing positive, zero and negative curvature respectively. This dynamic cosmological model of general relativity would come to form the standard for both the Big Bang and Steady State theories.

The name "Big Bang" was coined by Sir Fred Hoyle, who was a life-long proponent of the alternative "steady-state" theory of the universe. He used the phrase "big bang" in a sarcastic way.

Answer 2

Fred Hoyle coined the term Big Bang. He dismissed the idea of an explosion-like beginning to the Universe as 'cartoon physics' and thus the term Big Bang was derogatory. However the theory is now accepted by most scientists. The term Big Bang has stuck and is no longer derogatory. It may be one of the most entertaining terms of Cosmology.

Answer 3

Georges Lemaitre proposed a theory in 1927 that "hypothesised the primeval atom". Edwin Hubble worked on this theory to help prove it but it was Fred Hoyle that coined the term "BIG BANG" in 1949 when he was trying to take the mick out of the theory! However, he later contributed to the understanding of the origins of the universe. Cosmic background radiation was discovered accidentally in 1964 which became the strongest evidence for the BIG BANG theory and so now it is what most scientists believe to be true.
