Black holes are considered mysterious due to their time evolution and information processing. We claim that these properties are not specific to gravity but are generic for a class of objects, called saturons, that have maximal microstate entropy compatible with unitarity.
Saturons appear in a variety of calculable renormalizable theories in the form of solitons and other bound states. This universality has a wide range of implications not only for black hole physics but also for particle physics and quantum information processing in many-body systems.
