Actual picture of the law of universal gravitation and the quantum gravity theory describing the real state of the universe

This paper presents the real sense of the classical and quantum theory of gravitation as a component of the actual picture of the universe where the volume, as the size of the expanding universe, approaches infinity, while the total of material masses goes to zero. At present, these two standard theories describe the phenomenon of gravitation but do not explain the very mechanism and the cause of this process. This constant and real lack of information on that subject is consistent with natural laws and the same with the laws of physics, which were already experimentally determined by Werner Heisenberg in 1927. The paper also presents the causes of inability to explain up to the present the actual picture of the essence of the universe.
