Brian Greene | What is String Theory?

Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never found.

Brian Greene explains the basic idea of String Theory in under 3 minutes.

In the intervening decades, string theory has brought a collection of mind-boggling possibilities into the lexicon of mainstream thinking - extra dimensions of space, holographic worlds, and multiple universes.

Some researchers view these developments as symptoms of string theory having lost its way. Others argue that string theory, although very much still a work in progress, is revealing stunning new qualities of reality.

Join leading minds in theoretical physics for a whirlwind ride through the twists and turns of string theory - its past, its future, and what it tells us about the search for the universe’s final theory.
