What is Information? The strange thing is that the maximum information of a number of particles inside a volume can be calculated from the information content on a surface corresponding to these particles. When these particles form a black hole then the number of Planck areas on the Schwarzschild radius of this hole corresponds to the maximum information to be present inside that volume. Likewise, if we imagine a spherical surface somewher arbitrary in space, the maximum information matter can aquire inside this surface cirresponds to the number of Planck areas on that surface again. If the matter particles, carrying information, have the mass of a black hole with a Schwarzschild radius and event horizon that is the same as the enclosing imaginary surface, then that matter particles are in a state of maximum informatiin. Invariably. That is a boring state though. It the state of all that matter at one point or, complementary, of all matter evenly spread out on the surface.
Now nice forms of information, INformation, that is, are the ones that correspind to intermediate numbers. Which means not complete, or total order (all particles at one point for example, like in the center of a black hole), nor completd, or total disorder (like on the event horizon of a hole). It corresponds to ordered structures of matter or particles. The black hole is a complementary unit jn that it contains bith forms at once. Matter inside a volume (not having the configuration of a black hole state yet, can be nicely ordered and whirl around in formation. Not too much information and not too little being there.
