What is the medium thru which light waves are transmitted across space? Can we reasonably distinguish light from the information it is carrying? What would light that doesn't carry information be like? Is there any calculation of the amount of information that a light wave can carry? Does each wave of light correspond to one or many photons? Is the information carried by a light wave the same or different from the information carried by a photon? Where does the information light is carrying go when a light wave is absorbed into matter?
