The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The concept of an expanding universe was scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations .
The theory he devised to explain what he found is called the Big Bang theory. [citation needed] In 1931, Lemaître proposed in his "hypothèse de l'atome primitif" (hypothesis of the primeval atom) that the universe began with the "explosion" of the "primeval atom" – what was later called the Big Bang.
The theory was one alternative to the Big Bang which, like the Big Bang, agreed with key observations of the day, namely Hubble's red shift observations, and Hoyle was a strong critic of the Big Bang. He coined the term "Big Bang" on BBC radio's Third Programme broadcast on 28 March 1949. [28]
In “The Big Bang Theory,” Kripke was a fellow physicist at Cal-Tech and a frequent rival of Sheldon’s. Bowie originally joined the series in Season 2 and went on to appear in the show ...
After removing all potential sources of noise, including pigeon droppings on the antenna, the noise was finally identified as CMB, which served as important corroboration of the Big Bang theory. In 1970, Wilson led a team that made the first detection of a rotational spectral line of carbon monoxide (CO) in an astronomical object, the Orion ...
The Big Bang Theory has spent eight seasons making science fun and accessible to a wide audience. Now the show is working to make an education in science accessible to students who might not be ...
The astronomer Fred Hoyle introduced the term "Big Bang" in a 1949 BBC radio broadcast to refer to cosmological theories such as Lemaître's, according to which the Universe has a beginning in time. [31] [32] Hoyle remained throughout his life an opponent of such "Big Bang" theories, advocating instead a steady-state model of an eternal Universe.
