The Big Bang itself is a scientific theory, and as such, stands or falls by its agreement with observations. [2] However, as a theory which addresses the nature of the universe since its earliest discernible existence, the Big Bang carries possible theological implications regarding the concept of creation out of nothing.
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.
Big Bang cosmology (standard) – cosmology based on the Big Bang model of the universe. The Big Bang is a theoretical explosion from which all matter in the universe is alleged to have originated approximately 13.799 ± 0.021 billion years ago. Non-standard cosmology – any physical cosmological model of the universe that has been, or still ...
Lemaître is known as the first proponent of the big bang theory of the origins of the cosmos and pioneer in applying Einstein's theory of general relativity to cosmology. Einstein proposed Lemaitre for the 1934 Francqui Prize , which he received from the Belgian King.
The position of the Roman Catholic Church on the theory of evolution has changed over the last two centuries from a large period of no official mention, to a statement of neutrality in the early-1950s, to limited guarded acceptance in recent years, rejecting the materialistic and reductionist philosophies behind it, and insisting that the human ...
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 Big Bang model, or theory, is now the prevailing cosmological theory of the early development of the universe and was first proposed by Belgian priest Georges Lemaître, astronomer and professor of physics at the Catholic University of Leuven, with a Ph.D. from MIT. Lemaître was a pioneer in applying Albert Einstein's theory of general ...
