My understanding previously was that black holes are hashing the universe in a way, irretrievably reducing information to a more fundamental and irreversible state, while this article implies that actually, they're merely transforming the information and we have the ability to read a map (holographic extra-dimensional information from the emitted radiation) to resequence at least some of that information. Interesting to think about.
