Hace 2 días · Gamow disliked the term, and although Hoyle referred to it in his popular book The Nature of the Universe from 1950, he only used it again in 1965. In their seminal paper in the Astrophysical Journal of July 1965 , Dicke and his coauthors did not employ the term but instead wrote about the “primeval fireball” as the state of the early universe giving birth to the microwave background.
Hace 2 días · [Citation 10] George Gamow introduced the word “thermonuclear” in 1937–1938 [Citation 11] to mean reactions induced by hot ions with a thermalized distribution of kinetic energies. In the 1940s, the Los Alamos scientists used “thermonuclear,” though occasionally one finds variants such as “thermal nuclear” (see Arthur Compton’s 1942 letter that we reproduce in the Appendix ).
Hace 3 días · junio 23, 2024. Hoy, trataremos en nuestra columna uno de los temas misterio en la cosmología actual: la energía oscura. Hace unos 13.800 millones de años, el universo comenzó a experimentar una rápida expansión que llamamos el Big Bang. Después de esta expansión inicial, que duró una fracción de segundo, la gravedad comenzó a ...
Hace 5 días · Por su parte, George Gamow, con su famosa teoría del Big Bang ( o gran explosión) explica que el universo tuvo un origen en el tiempo.
Hace 21 horas · The cosmic microwave background was first predicted in 1948 by Ralph Alpher and Robert Herman, in a correction they prepared for a paper by Alpher's PhD advisor George Gamow. Alpher and Herman were able to estimate the temperature of the cosmic microwave background to be 5 K. [23]
Hace 3 días · Lewis Lichtenstein Strauss ( / ˈstrɔːz / STRAWZ; January 31, 1896 – January 21, 1974) was an American government official, businessman, philanthropist, and naval officer. He was one of the original members of the United States Atomic Energy Commission (AEC) in 1946 and he served as the commission's chair in the 1950s.
asking what came “before” the Big Bang is kinda like asking what is “north” of the North Pole. Not quite true, this is a common misconception (see 1 2 for some easily digestible videos).. The reality is that the Big Bang as we know it is best mathematically describe using Friedmann's solutions to Einstein's equations, extrapolated back in time (initially by George Gamow and others ...
