Abstract

This paper describes the derivation of formula for the galaxies’ recession velocities in the finite size model of the Universe. From this formula it is then derived the Hubble constant dependency on the distance from the Universe’s center, which is relatively near the Milky Way galaxy. It is shown that for this model of the Universe the Hubble constant for very distant objects is significantly reduced and, therefore, shouldn’t be measured and evaluated using the standard methods without corrections such as, for example, in gravitational lensing when such large distances and consequently the large redshifts are involved. The Hubble constant in this Universe is also independent of time.
