Abstract
The fundamental absence of dilation of the intrinsic time of matter, which moves in a gravitational field by inertia, and therefore the unreality of the Etherington's identity, is substantiated. The Hubble linear dependence of the redshift of the wavelengths of radiation on the transverse comoving distance instead of the luminosity distance is proved. The corre-spondence of this dependence to astronomical observations is shown. The variability of the Hubble constant in time, and therefore the presence of dark energy in the Universe, which supposedly accelerates or, vice versa, slows down the expansion of the Universe in the people's World, is refuted.
