General relativity is an excellent model of gravity, but the theory is classical, not described by a quantum theory. There are many models of quantum gravity, they can be divided into background and independent from the background of the theory. In this paper, we consider the canonical approach to quantum gravity. But a completely different geometry and the concept of space is used. Instead of real space, consider the geometry of the fields in the momentum space. For this, the coordinates are considered by operators who are set in the space of momentum.
