    "abstract": "According to the universal entropy bound, the entropy (and hence information\ncapacity) of a complete weakly self-gravitating physical system can be bounded\nexclusively in terms of its circumscribing radius and total gravitating energy.\nThe bound\u0027s correctness is supported by explicit statistical calculations of\nentropy, gedanken experiments involving the generalized second law, and\nBousso\u0027s covariant holographic bound. On the other hand, it is not always\nobvious in a particular example how the system avoids having too many states\nfor given energy, and hence violating the bound. We analyze in detail several\npurported counterexamples of this type (involving systems made of massive\nparticles, systems at low temperature, systems with high degeneracy of the\nlowest excited states, systems with degenerate ground states, or involving a\nparticle spectrum with proliferation of nearly massless species), and exhibit\nin each case the mechanism behind the bound\u0027s efficacy.",
