I've just started reading up on the holographic principle and eventually want to work my way to figuring out what Verlinde has proposed using it for. One thing I've noticed in a couple of papers is the mapping of the entropy of a black hole onto a holographic screen. Why are families of light rays considered for how the entropy is mapped to the screen? To me, it sounds like by introducing the light rays and the focusing theorem, we are talking about real physical photons mapping out the entropy, but that doesn't seem to make any sense since I haven't imagined the screen as a physical object.
We also know there exists orbits for photons around a BH, what is there to say about these paths? Would they simply not correspond to a point on the holograph that carries information about the BH? Or are these light rays simply tools to characterize the mappings?
