Session R9 - Non-Doppler Redshift Mechanisms with Possible Cosmological Applications.
ORAL session, Monday afternoon, April 07
Washington A, Loews Philadelphia Hotel
Deviations of the expanding Universe from the Hubble flow - peculiar motions and accelerated expansion - are remedied with artificial sources of gravitation, like an ad hoc Great Attractor and “dark energy” exacerbating the cosmological constant problem of general relativity that disagrees with its quantum mechanics counterpart by 120 orders of magnitude. These controversies can be evaded considering a different kinematical scheme with a periodic of sequence of Big Bangs. The dynamical mechanism behind this process has been investigated elsewhere. This scheme presents a harmonious picture of cosmological phenomena. Thus, it explains incongruity in physical and redshift positions of stellar objects ascribed to the acceleration of the Universe - slow far-away objects had been materialized in a previous Big Bang while fast nearby objects merely belong to the current Big Bang. A sensible explanation is provided to the existence of a small circle of blueshifted galaxies in the Virgo cluster - those are the slowest in the preceding Big Bang. In the suggested approach, the CMB is due to a different mechanism and contains a substantial non-Dopplerian dipole ingredient. Besides elucidating the origin of peculiar motions this offers a decisive Experimentum Crucis. As the non-Dopplerian ingredient is subtracted from the whole CMB dipole, the remaining velocity must aim at the Virgo cluster.
