The theory of the Big Bang was a culmination by various scientists of the 20th century such as Edwin Hubble, Albert Einstein, Aleksander Friedmann, George Ganau and finally termed by Fred Hoyle in 1950. It is interesting to see that this theory was discovered as recently as the 20th century, but was actually written in the Quran 21:30 in 600AD. "The heavens & the Earth were joined together and We split them thereunder" It is this splitting of the Heavens & the Earth that is referred to as the Big Bang.
