This work was conceived as a study tool, in order to expand the horizon of knowledge of the universe, by establishing some relationships of similarity between the microcosm and the macrocosm, regarding the ways of organizing matter in the two micro and macrocosmic levels, taking into account the interaction relationships of particles, respectively of bodies, existing in a certain space. If we refer to the form of organization of matter, we observe that at the microcosm level, matter is presented in granular, discrete form, such as; electrons, nucleons, mesons and other particles, while at the macrocosm level matter is presented in the form of satellites, planets, stars, nebulae, etc. Both in the microcosm and in the macrocosm matter is organized in systems of particles or celestial bodies, which are characterized by a periodic movement in a central field. In other words, cosmic systems of any size are rotational harmonic oscillators, in a permanent state of energetic balance with the environment. Any deviation from this balance leads to manifestations of energy absorption or emission from the respective systems, until their energetic rebalancing with the environment. If in the microcosm these energy exchanges can be observed in the laboratory in real time, in the macrocosm the events occur in thousands or millions of years, becoming impossible to study in their entirety. Although the nature of the fields that interact in the microcosm is different from that of the macrocosm fields, namely the electromagnetic and gravitational fields, they still have a common characteristic, that of being the binder of matter organized in harmonic systems, having an unlimited range of action, whose intensity decreases with the square of the distance, ensuring the conditions for the organization of particles or bodies in micro or macrocosm systems.
