On the nature of red shift of Metagalaxy

"In some cases the velocity of galaxies removal determined from the Doppler shift was very large and reached 0,3- 0,4 light velocity in a void (the blue and green lines were shifted to the red region of spectrum). Fig. 1 illustrates such measurement.

These observations qualitatively corroborated the hypothesis expressed by Soviet scientist Fridman (1923) about the expanding Universe which can be considered as the corollary of general Relativity, but the grandiose realm of phenomenon required to interpret and discuss it both physically and philosophically. In the course of this discussion, some astrophysical aspects of the problem have been refined and some suppositions of possible additional causes of the observed phenomenon have been expressed. We have to reject some of such suppositions as contradicting the entire amount of experimental facts (for example, the hypothesis of 'quanta ageing' that was popular at due time; it meant the frequency variation of light reaching us from the far galaxies and being the result of the energy lost which grows during the way the light has passed)" [9, p. 360- 361].

"The discussion of possibility to explain otherwise the metagalactic red shift showed that all other physical processes that have been used for such explanation, both hypothetical and actual, are insufficient. They either cannot at all cause the red shift (such is, for instance, the photon scattering on the Dirac's electron background or the spontaneous splitting of photons) or they cause too small red shift (such is, for instance, the gravity waves radiation by the EM waves) or they have to cause, except the red shift, such spurious phenomena which are actually absent (such is, for instance, the photon scattering at some particles). Thus, the longitudinal Doppler effect (in relation to the accompanying reference frame) is the only physical phenomenon with whose help we can explain the properties of metagalactic red shift" [8, p. 511- 512].

However the abundant discussions evidence that not everything is unambiguous in the red shift interpretation on the basis of longitudinal Doppler effect. In particular, we can see from (1) that the Hubble regularity itself does not describe any physical process - Doppler effect, photons ageing, multiple scattering, neither something else. The Hubble law only registers the fact of frequencies shift dependently on location of the source and observer in space. We do not see immediately the velocities of source and observer in this law. Supposing the relation between the Hubble law and Doppler effect, these velocities are introduced by the addition to this law some redetermining premises which do not follow from it directly. But it would be a logical requirement, the consequences of the introduced additional premises to be not discrepant with the known today conceptions of physical processes, in particular with the regularities of behaviour of gravitating bodies.

As we will show in this paper, the hypothesis of the galaxies scattering from the region of Big Bang is not non-discrepant. This does not allow us to be thinking that we have no problem with the conventional interpretation of metagalactic red shift.
