A relatively straight-forward (given the subject matter) video presentation explaining the mind boggling concept of not four dimensions (time being the fourth) but rather ten dimensions, based on the book Imagining the Tenth Dimension by Rob Bryanton.

Up until a few days ago I had no idea that there are (theoretically) ten dimensions to our universe. We’re all pretty familiar with 2D and 3D, but anything beyond that is pretty crazy.
