This 13 minute video in 3 parts explains how the Big Bang theory developed by looking at the evidence that supports it, including Hubble's theory of the birth of the universe, Hoyle's naming of it and Einstein's theory of energy and matter. Part 2 looks at what happened after the Big Bang - the emergence of the 4 fundamental forces - gravity, electromagnetism, strong and weak nuclear forces, and the formation of matter - quarks, protons, neutrons and electrons, in the form of a plasma. The ending of the plasma allowed atoms to form, and allowed photons to move freely. Part 3 presents further evidence for the Big Bang theory with the discovery in the 1960's of the flash of energy released.
