Abstract: Black holes  are considered mysterious due to their time evolution  and information processing.  We show that these properties are not specific to gravity but are generic for a class of objects, called saturons, which  saturate the upper bound on microstate degeneracy imposed by unitarity.  Saturons appear in a variety of calculable theories in the form of solitons and other bound states. We shall first explain the essence of the phenomenon using a simple prototype model applicable to many systems both in QFT and in many-body physics and later discuss implications.  The universality of the phenomenon allows us to understand the known black hole properties and to predict new features. Saturons have a wide range of implications not only for black hole physics but also for particle physics and for many-body systems.  These include prospects of laboratory studies.
