It is all the more puzzling that the result goes unmentioned in the book, especially as in places Penrose goes to great lengths to defend implausible assumptions—including some that fail to help his case. He sup-
poses that information is lost in black holes, apparently in the belief that this would imply that black holes destroy disorder. But if this assumption were true, it would only make his task more hopeless. Information, in a
very precise sense, is the opposite of dis-order. Penrose’s assumed information loss would introduce fundamental ignorance
about the microscopic state of the Hawk-ing cloud (thus increasing its “fi ne-grained entropy”) while having no effect on the macroscopic disorder (the “coarse-grained entropy”), which increases in any case.
