Discovery Of A Major Contradiction In Big Bang Cosmology Points To The New Cosmic Center Universe Model

Abstract: The BAL z =3 .91 quasar’s high Fe/O ratio has led to a reexamination of big bang’s spacetime expansion postulate and the discovery that it predicts a CBR redshift of z> 36000 instead of the widely accepted z ∼ 1000. This result leads an expansion-predicted CBR temperature of only T =0 .08 K, which is contradicted by the experimental TCBR =2 .73 K. Contrary to longheld belief, these results strongly suggest that the F-L expanding spacetime paradigm, with its expansion redshifts, is not the correct relativistic description of the universe. This conclusion agrees with the earlier finding (gr-qc/9806061) that the universe is relativistically governed by the Einstein static spacetime solution of the field equations, not the F-L solution. Disproof of expansion redshifts removes the only support for the Cosmological Principle, thus showing that the spherical symmetry of the cosmos demanded by the Hubble redshift relation can no longer be attributed to the universe being the same everywhere. The Cosmological Principle is flawed. Instead of the universe being both homogeneous and isotropic, instead it is only isotropic about a nearby universal Center. These results suggest that the new Cosmic Center Universe model, based on Einstein’s static spacetime solution of the field equations, deserves the attention of the scientific community. One significant advantage of the new model is that it restores conservation of energy to physics, in stark contrast to the big bang, which involved gargantuan nonconservation of CBR energy losses amounting to more than thirty million times the baryonic mass of the visible universe (gr-qc/9806061).

Particle Horizons in Cosmology

Abstract: The importance of investigating particle horizons in order to interpret a cosmological solution of Einstein’s field equations has been described. We have presented the formula and studied the particle horizons in some of the cosmological models presented in our earlier papers. It is well known that the Friedman-Robertson-Walker (F-R-W) models, the energy density of the free gravitational field denoted by e, equivalently denoted by MacCallum parameter ξ, vanishes but the particle horizons exist and thus the former has no bearing on the latter. However, we have shown in our models presented herein that e is related with particle horizons. Further, it is shown that as e grows, the segment of the corresponding particle horizon decreases and thus the radius of the corresponding visible universe decreases.

Random inflation and global geometry of the universe

Abstract: Either an inflationary fluctuation in the early universe is a mole's hole (this is possible in either a closed or open universe) or the fluctuation occupies more than half of a closed universe. Other possibilities are extremely exotic.
