British astronomer Sir Fred Hoyle first coined the term the Big Bang in 1950. The theory explains much of what we have observed in the universe, but it does leave some things unexplained. The video discusses the Cosmic Inflation theory proposed in the 1980s, which solves two of the biggest problems with the original Big Bang theory.
