A INOVAÇÃO DO Pe. GEORGE LEMAÎTRE NA COSMOLOGIA: O BIG- BANG

Abstract

For several decades the physicists, including brazilians, they have traditionally, it has been
considered that the father of theory of Big-Bang is the american- soviet physicist George
Gamow, whose studies and research provide essential contributions to the explanation of
the origins of the universe and the consolidation of the Big Bang theory. But they has overlooked the achievements in Cosmology of the belgian priest and Georges Lemaître. In 1927
he became the first to propose a theory of the expansion of the universe to explain the redshifts of galaxies, an advance that is often attributed to Edwin Hubble. Lemaître published
the original version of the Hubble Law, and he produced the first estimate of the Hubble
constant. He proposed the theory of expansion of the Universe that became better known
as the Big Bang theory for the origin of the universe. Alexander Friedmann, Carl Wilhelm
Wirtz, Vesto Slipher, Knut E. Lundmark, Willem de Sitter, Georges H. Lemaître, and Edwin
Hubble all contributed to the discovery of the expansion of the universe. If only two persons
are to be ranked as the most important ones for the general acceptance of the expansion of
the universe, the historical evidence points at Lemaître and Hubble, and the proper answer
to the question, who discovered the expansion of the universe, is: Georges H. Lemaître.
