What year was the first big bang theory?

Answer 1

Georges-Henri Lemaitre was born in Charleroi, Belgium on 17 July 1894. Lemaitre studied humanities at a Jesuit school before entering the civil engineering school of the Catholic University of Leuven at the age of 17. Fred Hoyle is credited with coining the term Big Bang during a 1949 radio broadcast. It is popularly reported that Hoyle, who favored an alternative "steady state" cosmological model, at the time, proposed the term Big Bang as a striking image meant to highlight the difference between the two models. The consensus for modeling cosmology was agreed upon based on the work of four scientists: Alexander Friedmann, Georges Lemaître, Howard Percy Robertson, and Arthur Geoffrey Walker. It was developed independently by the named authors in the 1920s and 1930s. Occasionally referred to as the FLRW, FRW, FL, or RW (e.g., a complete or partial combination of their last initials) Universe, it presents a metric used to explain Einstein's field equation of general relativity and thus became the foundation for the currently understood version of the standard 'Big Bang Theory'.

Answer 2

Georges Lemaître proposed the universe's expansion from a single point in 1927. Fred Hoyle (an opponent) coined the term "Big Bang" in 1949. The event itself is estimated to have occurred 13.73 billion years ago.

Answer 3

The theory of the big bang was first proposed by Georges Lemaitre a Belgian Monsignor born in 1894. He published a paper in 1927 called (in English) "A homogeneous Universe of constant mass and growing radius accounting for the radial velocity of extragalactic nebulae". Roles of the tongue doesn't it! It was Fred Hoyle who gave it the name "The Big Bang" as a sarcastic remark as he didn't think the theory was correct and preferred the Steady State theory of the Universe instead!

Answer 4

When, in 1964, Robert Wilson and Arno Penzias found (COMPLETELY by accident) the existence of radiation that was exactly as predicted by Big Bang Cosmology, this idea went from minority acceptance to almost universal acceptance in the scientific community. When a hypothesis makes a prediction that turns out to perfectly match an observation, and a counter-hypothesis completely fails to make such a prediction, the scientific approach demands that the latter hypothesis must be abandoned.

Answer 5

It premiered on CBS on 24th September 2007 which means it is almost six years old.
