Big Bang
The standard cosmological model in Astronomy, holding that the universe began about 13.8 billion years ago in an extremely hot, dense state and has been expanding ever since.
'Big Bang' was named by the theory's chief opponent. British astronomer Fred Hoyle coined it in a 1949 BBC lecture to contrast his Steady State cosmology with the notion that all matter erupted from nothing at one moment. The label went global; Hoyle never accepted the theory.
