Higher Dimensions from String Theory

String Theory predicts the existence of more than the 3 space
dimensions and 1 time dimension we are all familiar with. According
to string theory, there are additional dimensions that we are
unfamiliar with because they are curled up into tiny complicated
shapes that can only be seen on tiny scales. If we could shrink to
this tiny, Planck-sized scale we could see that at every 3D point in
space, we can also explore 6 additional dimensions. This animation
shows a Calabi-Yau surface which is a projection of these
higher dimensions into the more familiar dimensions we are aware of.
Brian Greene's book, The Elegant Universe, was made into a
documentary and has a chapter that does a good job of explaining this
concept. See Chapter 7 of Hour 2, titled "Multiple Dimensions", to watch
a 7 minute
Quicktime movie that describes this in more detail.
