Einstein formula for gravitational radiation does not follow from general relativity theory

It is shown that the intensity of gravitational radiation and complete intensity defined in general relativity theory according to Einstein are dependent of the choice of coordinate system and as a result they may vanish or even become negative. Hence the well-known Einstein quadrupole formula which is as a rule used for calculations in general relativity theory is not a consequence of general relativity theory and is not contained in the latter. This result is just one particular consequence of the general statement about the absence of energy-momentum conservation laws for a system including the matter and the gravitational field in general relativity theory
