String Theory or Loop Quantum Gravity?

David Gross vs Carlo Rovelli

String theory has dominated discussions at the frontiers of physics for decades, especially in the attempts to build a quantum theory of gravity. But does it deserve its exalted status? Nobel Prize winner and String Theory pioneer David Gross debates Carlo Rovelli, one of the founding fathers of Loop Quantum Gravity. The discussion is lively; full of insights, insults, backhanded compliments and even some common ground as to the nature of physics.
