Suppose there is an extra compact spacial dimension in addition to familiar space dimensions x, y, and z. Let us suppose that matter is some kind of 3 dimensional surface moving in these 4 spacial dimensions, 4-space, in some cyclical manner. Let us suppose that from the shape of the surface we can get physics. Assume as an observer we ourselves are some complicated 3 dimensional surface in 4-space. Now as observers we only notice the dimensions x, y, and z. At a given instant matter is "distributed" about in 4-space so that in 3-space at a given instant matter is but a 2 dimensional surface in 3-space. Matter is nowhere and in time everywhere. Thanks for any thoughts or help making this more interesting.
