TED's posted a couple of talks based on the search for extra-dimensional space and the Large Hadron Collider (LHC). Brian Cox and Brian Greene believe there's more to the universe than the conventional three-plus-one dimensions, mainly because there's a bunch of equations out there that don't seem to work. So rather than spend $1.50 on a pad of paper and a 2B pencil to create new equations that do work, physicists instead spent US$10 billion on a machine to tell them how the wrong equations could work. Or something.
In any case, both speakers wax on about string theory, relativity, and sub-atomic particles in a way that a child could understand. Greene's talk is below, and head to over to TED to see Cox and hundreds of other smart and creative people be smart and creative.
