What is the Big Bang, who came up with idea and why do we believe in it? Simon Singh told the story of the Big Bang theory, from its birth in the 1920s to the observational evidence that backed it and then clinched it. As well as discovering the development of the Big Bang theory, Simon also discussed more generally how new scientific ideas are invented, developed and adopted, which included the partnership between theory and experiment and the role of personalities and politics.
Simon Singh is the author of Fermat's Last Theorem and The Code Book, and he has just published Big Bang, the story behind one of the most important theories in the history of science.
