We have a somewhat similar problem of the man in Flatland trying to understand time. We cannot really define time because it is not in our three- dimensional framework. Anything functioning in any of these eleven dimensions beyond our X,Y and Z directions is not able to be observed or described in physical terms. The evidence from light that dimensions influence the behavior of matter. Another area which shows dimensional considerations different than our own is seen in the nature of light.
Light is a two-dimensional quantity.
Like the man in Flatland, light has no thickness. Light is referred to as electromagnetic radiation because it has an electrical component, and a magnetic component, but no thickness. Light has some very strange properties. When it is moving, it has mass properties, but when you stop it, the mass disappears. Not only does light have a zero rest mass, but it can be polarized.
