Can the Existence of Dark Energy Shed Light on the Dark Sides of the ”Byurakan Concept”?

The Ambartsumian’s idea on the existence of superdense matter and its decay due to evolution is considered using the new observational data. We suggest a new approach to the problem using the number density of baryons for describing the cosmic object instead of mass density. The atomic nuclei and baryons increase their mass due to the gradual decrease of the nuclear binding energy, which, in its turn, takes place as a result of the influence of dark energy. This effect increases the mass of all cosmic objects and the Universe as a whole. Apparently, the smart mechanism of transformation of the mass into energy and vice versa in the atomic nuclei level regulates mass density everywhere. The self-consistent change of the baryonic mass and their number density maintain the balance in the baryonic world.
