Gravitational Waves Versus Cosmological Perturbations: Commentary to Mukhanov's Talk

Authors: Lukasz Andrzej Glinka

Recently, on the conference "Quantum Theory and Gravitation" held in Zürich on June 14-24, 2011, V.F. Mukhanov has been presented talk "Massive Gravity" discussing the relationships between massive gravitational waves and Cosmological Perturbations of the Minkowski background. His crucial result was modification of the Newtonian potential of universal gravitation due to a multiplicative constant equal to 4=3. However, this presentation has been stirred up my negative opinion. The controversy has been caused by absence of a lot of details, what have been made the talk manifestly misleading. The lecturer did not respond to my questions satisfactory. Mukhanov's deductions are at most half-true, and they can be easily verified by straightforward calculations. In this paper I explain shortly what is right and what is wrong in the approach propagated by Mukhanov. Particularly, I shall to show that restoration of the Newton law of universal gravitation is unambiguous.
