Thirty-five years ago, string theory took physics by storm, promising the coveted unified theory of the forces of nature that Einstein valiantly searched for but never found. In the decades since, string theory has introduced a mind-boggling set of possibilities into the lexicon of mainstream thought: additional dimensions of space, holographic worlds, and multiple universes. Some researchers view these developments as symptoms of a misguided string theory. Others argue that string theory, although still a work in progress, reveals astonishing new qualities of reality. Join the greatest minds in theoretical physics for a whirlwind journey through the twists and turns of string theory: its past, its future, and what it tells us about the search for the final theory of the universe.

PARTICIPANTS: Marcelo Gleiser, Michael Dine, Andrew Strominger
