Is this the foundation for the "holographic" description of the universe? Photons, traveling at the speed of light, effectively don't see one of the dimensions, so can be described using "N-1" dimensions. (Edit: Or does zero rest mass make them a special case?) Can someone also confirm whether the following thinking is valid? The expansion of space means that the edge of the observable universe appears to be receding at the speed of light. As such, it has "N-1" dimensions and that is where the idea of a holographic boundary comes from? The same reasoning applies to the "N-1" dimensions of the event horizon in a black hole?
