The homogeneous isotropic empty space was described here based on its metric. The only parameter of this metric was taken to be equal to the Hubble constant. The tensor of energy-momentum of empty space was calculated. Upon this, the density of the empty homogeneous space turned to be equal to the expected density of the Universe. In other words, the density of the empty space is the “dark energy”. Of not less importance is the fact that the same metric imposes the exponentially increasing law of the red shift asymptotically close to the Hubble law at little red shift values. The solution has no singularities.
