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?
