Coined by English astronomer Fred Hoyle on the BBC Third Programme, broadcast at 18:30 GMT on 28 March 1949. It is a popular but misinformed belief that this was intended as a derogatory term, Hoyle being a proponent of the opposing steady state theory, but Hoyle himself has rejected that notion.

The Big Bang model or theory is the prevailing cosmological theory of the early development of the universe. According to the Big Bang model, the universe was originally in an extremely hot and dense state that expanded rapidly. This expansion caused the universe to cool and resulted in the present diluted state that continues to expand today. Based on the best available measurements as of 2010, the original state of the universe existed around 13.7 billion years ago, which is often referred to as the time when the Big Bang occurred. The theory is the most comprehensive and accurate explanation supported by scientific evidence and observations.
