Properties of a closed subsystem in an infinite system

One of the main shortcomings of modern theories for describing reality is the introduction of the concepts of space and time into the theory regardless of the object of study (matter). In this paper, we study the properties of a closed subsystem in an infinite system. It is shown that with successive transitions from one subsystem to another, the Minkowski space is induced in the subsystem, taking into account the presence of matter in it. Using the example of modeling the localization and motion of a free particle, interpretations are given for concepts such as the wave function, the Heisenberg uncertainty principle, the particle spin, the phase velocity, and the fine structure constant. According to the proposed concept, the theory assumes the existence of splitting of energy levels in a free charged particle. The representation allows us to identify the relationship between the principle of least action and the law of increasing entropy of a closed system. The developed model assumes accelerated expansion of the subsystem space, which leads to the emergence of gravitational interaction between the objects of the subsystem. It is shown that the law of increasing entropy is reflected inside the subsystem in the form of the principle of least action and the phenomenon of gravity. The proposed representation can be used in developing the theory of quantum gravity.
