Abstract In Einstein equation, there is seen an absence of a gravity field as a source of another gravity field. That is why for the Einstein equation solutions, the local law of energy-momentum conservation is not true. Lass proposed a homogeneous metric. Based on this metric, we obtained the exact metric of a homogeneous gravitational field. This metric generates a plausible field energy density and regular vacuum tensions. The exact metric of homogeneous fields does not belong to Einstein equation solutions. That is why, the problem arouses of constructing of a gravity field equation based on new principles.
