Gravitational field and cosmological expansion

In fundamental theories, where the concepts of space and time are introduced a priori, a contradiction arises. According to the relational concept of space and time, the latter should not be considered separately from matter. This concept is due to the general theory of relativity. Experimental studies carried out in order to check Bell's inequality have proved that quantum nonlocality takes place in the fundamental structure of reality, i.e. some holistic structure. This means that each particle has some mysterious connection with its environment, which is also consistent with the relational concept of spacetime. Therefore, in the study of the fundamental structure of reality, we relied on the idea that physical reality manifests itself as a result of the superposition of independent systems. This view differs in that it is consistent with the relational concept of space-time. At the end of the twentieth century, an accelerated expansion of the space of our universe was discovered. This discovery contributed to the emergence of the idea of the presence of dark energy. The accelerated expansion of space is due to the law of increasing entropy of a closed system. On the basis of the concept of superposition of systems, the condition of the closedness of the system was determined, from which the law of increasing entropy and expansion of the Minkowski space follow. In this paper, we consider the gravitational field induced by the accelerated expansion of space according to the Hubble law. It is shown that with the exponential expansion of space, a radial gravitational field is induced. Calculations have shown that this field corresponds to the gravitational field of field sources uniformly distributed over the volume of space. Moreover, each object has a mass and a property that attracts other objects. A cosmological model of the universe with similar objects is presented. In it, the universe is limited by the event horizon and is a closed system in it. The developed mathematical model allows calculating the distribution of the gravitational potential of the proposed model. Einstein's formula E = mc2 is obtained, which represents the potential energy of an object.
