N2 - Equation for gravitational wave (GW) propagation over arbitrary curved spacetime is derived in the presented work. Two new terms are found which absent in the conventional homogeneous and isotropic Friedmann cosmology. In conclusion we emphasize that these new terms can significantly change the character of solutions and assume that one of the terms may be the cause of relic GW amplitude suppression.
