The Big Bang theory changed how we understand our universe. But who do we have to thank for it? On this ID The Future, host Andrew McDiarmid concludes his conversation with esteemed cosmologist Jean-Pierre Luminet, who sets the record straight on the real heroes of the Big Bang Theory with his new book The Big Bang Revolutionaries, available now from Discovery Institute Press. In Part 2, Dr. Luminet sheds more light on chief architect George Lemaitre, as well as Alexander Friedmann and George Gamow. He also discusses how the Big Bang model stands up to scrutiny today. This is Part 2 of a two-part conversation.
