Seeing New Dimensions

The video's not too bad. Pretty cheesey, but good in terms of the informational content. How'd you find it anyway? Another thing to point out about extra spatial dimensions though is that they don't have to extended as in the movie, meaning that they don't have to be large like the spatial dimensions we're used to. They could instead be "curled up" into little compact manifolds, just like the little curled up dimension of a garden hose isn't all that apparent unless you examine it close-up. In fact in string theory, 6 of the extra predicted dimensions are of the curled up variety, meaning that at every point in our universe there are 6 extra space dimensions bound up in a shape called a Calabi-Yau manifold. There's a nice little article on Wikipedia about this kind of "compactified" dimenion: http://en.wikipedia.org/wiki/Compactification_%28physics%29
