HARDtalk

How did the universe come to be? Are there laws of physics which explain everything from the smallest particles to black holes? Theoretical physicist Lee Smolin is hoping that a hugely expensive experiment in particle physics to be conducted in a tunnel under a Swiss mountain may answer these questions. In his new book "The Trouble with Physics" he argues that scientists have been misled by a damaging dogma, so-called "string theory". Stephen Sackur asks him if that isn't the answer, what is?

Professor Richard Dawkins is a scientist who has set out to debunk the world's monotheistic religions. Stephen Sackur asks him if his brand of atheism is any less fundamentalist and faith-based than the religions it seeks to replace.
