  The detection and the research of the neutrinos background of
  Universe are the attractive problems. This problems do not seem the
unpromising one in the case of the high neutrinos density of Universe. It is
offered to use the low energy neutrinos background of Universe for the
explanation of the gravitational phenomena with the quantum position attracting
the Casimir's effect for this. As a result it can consider the normal matter
(not neutrinos) in the capasity of the
  Brownian particles by the help of which it can make the attempt to estimate
the statistic characteristics of the Universe neutrinos background.
