A critical analysis of the general theory of relativity shows that the adoption of its conception leads, first, to the abandonment of the conservation laws for energy, momentum, and angular momentum of matter and the gravitational field taken together and, second, to the abandonment of the idea of a gravitational field as a classical field of Faraday-Maxwell type possessing an energy-momentum density. For many physicists who have occupied themselves with general relativity the first point is still obscure, while others are inclined to regard this abandonment as the greatest achievement of the theory in overthrowing a concept such as energy. However, neither in the macroscopic nor the microscopic world is there a single experimental indication that directly or indirectly casts doubt on the validity of the conservation laws for matter, and therefore there are no physical grounds for abandoning these laws. Everything just mentioned is discussed in sufficient detail in our monograph [i], where references to original studies are also given.
