TED Talks - Brian Greene: The Universe on a String

A cool TED Talk by Brian Greene on superstring theory, made simple for the rest of us.

In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva.)

If you want to know more -- and you know you do -- you can check our Greene's series over at PBS, The Elegant Universe.
