Or put in more simplistic terms, as Bekenstein and Hawking argued in the mid-70s, the amount of information that a black hole can store is a function of its surface area, not its volume as one might naively expect. So the maximum amount of information that can be stored in *any* volume of space will always be bounded - the same amount of information that can be stored on the surface of a black hole that contains exactly that volume of space. So for any chunk of space, a full description of it could be encoded by the surface that encompasses it - much as a 2-dimensional hologram can encode all the information of a 3-dimensional scene. If this is true for a chunk of space, it should be true for the whole universe. (Of course, we're rather ignorant of any "surface" encompassing the universe.)
