We present an enlargement of General Relativity governed by a scalar Lagrangian mass, function of all the independent even scalars one is intelligent to build apiece powers of the Ricci tensor. The new conditions arising in the statement Einstein filed equatings, in the viewpoint of common General Relativity, may be elucidated as dark matter and dark strength contributions. Metricity condition completed by a new tensor different than the common metric tensor is too obtained. More it is proved that Schwarzschild-De Sitter, Robertson-Walker-De Sitter and Kerr-De Sitter metrics are exact answers to the new field equatings. Remarkably the form of the equation of the geodesic courses of particle motions across time in relativity theory remains the same in Einstein General Relativity unless the cosmological loyal Λ is no longer a uninterrupted appropriate a function of the space-time coordinate.
