—The paper is devoted to some of the difficulties which the Wheeler-DeWitt quantum geometrodynamics encountered, in particular, a strong mathematical proof that this theory is gauge-invariant, the definition of the wave function of the Universe through a path integral and the illegality of asymptotic boundary conditions in quantum gravity, the derivation of the Wheeler-DeWitt equation from the path integral and the equivalence of the Dirac quantization scheme with other approaches, the problem of definition of physical states in quantum gravity, possible realizations of the Everett concept of “relative states.” These problems are rarely discussed in the literature. They are related to the guiding idea that quantum theory of gravity must be gauge-invariant. It will lead to the question if it is possible to achieve this goal in a mathematically consistent way.
