Einstein dreamed of a unified theory of nature’s laws. String theory has long promised to deliver it: a mathematically elegant description that some have called a “theory of everything.” Join one of the most influential groups of theorists ever assembled on a single stage to evaluate the current state of this most ambitious of theories.

The Big Ideas Series is supported in part by the John Templeton Foundation.
