The nature of dark matter is one of the issues most actively discussed in both cosmology and particle physics. The progress in observational cosmology and determination of many parameters of the standard cosmological model (SCM) is insufficient to shed light on the nature of dark energy, the origin of the particle-antiparticle asymmetry in the Universe, the causes of the inflationary period, the cosmological lithium problem, etc. This paper attempted to gain a new insight into the nature of the dark matter through the idea of G. Gamow (1946) who assumed that a primordial hot universe consisted only of neutrons. The assumption is argued that the dark matter consists of baryons (neutrons) similar to ordinary matter (neutrons and protons). Experiments are proposed to confirm this hypothesis.
