Our model is inspired by the tired-light theory that was first proposed by [1] to explain

cosmological redshifts, which has been subject to other investigations [2-4].

under the assumption that the cosmological redshift is a result of the Doppler effect in an expanding space.

As a result, the predicted cosmological redshift is limited by the numerical value [z.

So, in his theory, Lemaitre calculated the cosmological redshift in a roundabout way: by substituting, into the Doppler formula of classical physics, the speed of change of the curvature radius R he obtained his redshift law, i.

The cosmological redshift of a remote galaxy is figured from this simple expression:

Perhaps with the Doppler interpretation of the cosmological redshift reconsidered -- and rejected -- we can at last embrace the essential beauty and mystery of cosmic expansion as originally envisioned by its discoverers.

Observations of galaxies and distributions of galaxies are beginning to suggest conflicts with the standard concept of an expanding Universe and its interpretation of a high-z redshift as a cosmological redshift.

There is no need for expansion of space and its cosmological redshift to explain the SNe1a data.

Distant redshifted SNe1a light sources from the Universe that are usually interpreted as cosmological redshifts are shown to be universal gravitational redshifts seen by all observers in the quantum celestial mechanics (QCM) approach to cosmology.

The difference between dopplerian and cosmological redshifts is discussed by Bedran [2].

Note that the galactic density profiles obtained with cosmological redshifts and dopplerian redshifts are very similar.

The theoretical evolution of the galactic density with respect to the present density assuming no new formation of galaxies (figure 3) was computed assuming cosmological redshifts with eq.
