The Big Bang

The educational documentary "The Big Bang" explores the disputed scientific theory on the origins of the universe. The Big Bang has been one of the dominant theories regarding the beginnings of the universe since the 1950s, and was initially suggested by the observation, made in 1928 by astronomer Edwin Hubble, that the universe itself seems to be expanding. This theory posits that the entire visible universe was once packed into a piece of matter the size of an atom, but that the massive energy contained within it caused it explode massively, launching the creation of the universe as we know and experience it. "The Big Bang" looks at the scientific knowledge that supports this unusual and still contentious theory.
