Abstract

In the work [7], the classical concepts of thermodynamic entropy are systematized and modern approaches to assessing the tribo-fatigue and mechanothermodynamic entropy of non-additive systems are outlined. In this article, the concept of the analogy of thermodynamics and mechanics of black holes is presented and analyzed, which made it possible to estimate their (thermodynamic) entropy. The insufficiency of this concept is that thermodynamic entropy is a characteristic of energy dissipation, whereas black holes are characterized by the absorption of energy and matter. In this regard, it is proposed to consider the event horizon as a hermodynamic medium, and a black hole as a tribo-fatigue object. And then the “black hole — event horizon” system is presented as a combined mechanothermodynamic non-additive multisystem. Methods for estimating the total (mechanothermodynamic) entropy and its components — tribo-fatigue and thermodynamic entropy in black hole mechanics are presented. With regard to individual (specific) zones and objects of the universe, the well-known theory of Zeldovich is accordingly modified: the universe is a thermodynamic medium with discretely distributed (scattered) dense and/or solid bodies (objects) — stars, galaxies, etc. Behavior of such a system (direct and back effects in the universe) are described. The peculiarity of the action of the medium on the stars and, conversely, the action of the cluster of stars on the interaction between them consists in the fact that it is non-Newtonian: action is not equal to reaction. It is the inequality of action against counteraction, which has radically different mechanisms and consequences (results), or, in other words, the imbalance of the universe that determine its general motion in space–time. The changing set of all states is the evolution of the universe. The analysis of possible strategies for the evolution of mechanothermodynamic systems is carried out on the basis of the fundamental principle: the damageability of everything that exists has no conceivable boundaries. This principle is formulated in mechanothermodynamics and used in philosophy to create a generalized theory of the evolution of the material world.
