We present here a self-consistent analysis of the physical effects recognizable if the accelerated expansion of the Universe is not the prerogative of the large structure of the Universe, but affects all the scales measurable. Some expansion phenomena observed in our vicinity are examined in detail from this point of view. The very fact that galaxies accelerate under the influence of dark energy is considered as the crucial evidence of the interaction between baryonic matter and the carrier of dark energy. Therefore, the second law of thermodynamics is applicable to this interaction process. Then one should take into account that all the baryonic objects starting with atomic nuclei and up to galaxies and their systems exist exceptionally due to their negative potential energy or mass defect in the case of atomic nuclei, while dark energy is purely positive. Bearing this in mind one arrive at a conclusion that due to this interaction: (1) the nuclear binding energy decreases gradually due to injection of positive energy into the atomic nuclei; (2) it makes the nuclei more and more unstable; (3) the decreased part of binding energy transforms into the mass, which increases the mass of nuclei. We argue that this effect shows up in all cosmic objects at all the hierarchical levels and governs their evolutional path. Particularly, this conclusion allows one to state that all the cosmic objects and the Universe as a whole increase their mass during their evolution. We suggested a method and calculated the solar mass annual growth using the relevant observational data. The results presented in the talk are published in the recent papers of the author.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
