We discuss the physical meaning of the nonmetricity vector. A relationship between the time derivative of the nonmetricity vector and the Hubble constant is revealed. On the basis of a solution to the equation for the nonmetricity field, it is concluded that the expansion rate of the Universe is different at different points of the Universe. This process can be a cause of the large-scale inhomogeneity of the Universe.
