Ralph Asher Alpher (February 3, 1921 – August 12, 2007) was an American cosmologist, who carried out pioneering work in the early 1950s on the Big Bang model, including Big Bang nucleosynthesis and predictions of the cosmic microwave background radiation.
In physical cosmology, the Alpher–Bethe–Gamow paper, or αβγ paper, was created by Ralph Alpher, then a physics PhD student, his advisor George Gamow, and Hans Bethe. The work, which would become the subject of Alpher's PhD dissertation, argued that the Big Bang would create hydrogen , helium and heavier elements in the correct ...
Robert Herman (August 29, 1914 – February 13, 1997) was an American astronomer, best known for his work with Ralph Alpher in 1948–50, on estimating the temperature of cosmic microwave background radiation from the Big Bang explosion.
The other was Lemaître's Big Bang theory, advocated and developed by George Gamow, who introduced BBN [76] and whose associates, Ralph Alpher and Robert Herman, predicted the CMB. [77] Ironically, it was Hoyle who coined the phrase that came to be applied to Lemaître's theory, referring to it as "this big bang idea" during a BBC Radio ...
2005 – Ralph A. Alpher is awarded the National Medal of Science for his groundbreaking work in nucleosynthesis and prediction that the universe expansion leaves behind background radiation, thus providing a model for the Big Bang theory.
The Big Bang Theory is over but several members of the original cast have found ways to make cameos on other shows in the franchise — including Young Sheldon and Georgie and Mandy's First Marriage.
Gamow's work led the development of the hot "big bang" theory of the expanding universe. He was the earliest to employ Alexander Friedmann's and Georges Lemaître's non-static solutions of Einstein's gravitational equations describing a universe of uniform matter density and constant spatial curvature. Gamow's crucial advance would provide a ...
The new book, The Big Bang Theory: The Definitive, Inside Story of the Epic Hit Series by Jessica Radloff, details how actresses Marisa Tomei, Tara Reid and Elizabeth Berkley were all up for the ...
