Until the 1960's, scientists held to the Steady State theory that the universe has no beginning or end in time and that the earth has always existed in one form or another. They scoffed at the Bible for saying that the earth had a beginning.
The first use of the term 'big bang' was by astronomer Fred Hoyle on a BBC broadcast in 1949 when he said: 'These theories were based on the hypothesis that all matter in the universe was created in one big bang at a particular time in the remote past.'
He argued against the theory and said was 'irrational and outside science.'
But, as a result of better telescopes and observations of the universe's constant expansion, by the 1980's the 'big bang' was the predominant theory of astronomers and astrophysicists.
