'Black holes have become one of the liveliest areas of theoretical research. By thinking about these cosmic objects, using quantum theory and relativity, theorists are clarifying our understanding of information, gravity and the other fundamental forces of nature. Stanford University’s Lenny Susskind is one of the leaders in this field. In this lively interview, he describes how he made the transition from plumbing to particle physics, and why theoretical physics is now so exciting.



This is one of a series of interviews given by world-class experts to Graham on the themes he explores in his new book The Universe Speaks in Numbers.
