  The largest and most detailed map of the distribution of dark matter in the
Universe has been recently created by the DES team. The distribution was found
to be slightly (be few percent) smoother, less clumpy than predicted by the
general relativity. This result was considered as a hint of some new physical
laws. In the present paper we offer a relatively simple model that could
explain the above result without resorting to any new physical laws. The model
deals with the dynamics of a system consisting of a large number of gravitating
neutral particles, whose mass is equal to the mass of hydrogen atoms. The
central point of the model is a partial inhibition of the gravitation for a
relatively small subsystem of the entire system. It would be sufficient for
this subsystem to constitute just about few percent of the total ensemble of
the particles for explaining the few percent more smooth distribution of dark
matter (observed by the DES team) compared to the prediction of the general
relativity. The most viable candidate for the dark matter particles in this
model is the second flavor of hydrogen atoms (SFHA) that has only S-states and
therefore does not couple to the electric dipole radiation or even to higher
multipole radiation, so that the SFHA is practically dark. The SFHA has the
experimental confirmation from atomic experiments, it does not go beyond the
Standard Model, it is based on the standard quantum mechanics, and it explains
the puzzling astrophysical observations of the redshifted line 21 cm from the
early Universe. Thus, our model explaining the DES result of a little too
smooth distribution of dark matter without resorting to any new physical laws
seems to be self-consistent.
