Tom Whyntie: The beginning of the universe for beginners (2013x149)

How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat energy and activity of the first few seconds of our universe from right after the Big Bang. [Directed by Dan Abdo and Jason Patterson, narrated by R.J. Glass].
