The description of gravitation by curved spacetime is a grand concept due to Albert Einstein. The form of his field equations for the determination of the metric coefficients for a given distribution of matter and field stress-energy is an assumption. The source term (right hand side) of these equations for the Einstein-Hilbert curvature tensor is taken to be the stress-energy tensor [] of all matter and fields except that of the gravitational field itself [].
