"SIGNIFICANT PROBLEMS WITH THE CURRENT THEORY OF INFLATIONARY COSMOLOGY"
Two discoveries: one theoretical (A.Friedmann, 1922-24)
of non-stationary cosmological solutions of Einstein equations, and the
other observational (V.Slipher, 1910; E. Hubble, 1929) of the expansion
of our Universe determined the success of the Big Bang cosmological idea.
It, however, predicts in the past a "cosmological singularity" that cannot
be physically described either directly or indirectly. The origin of the
universe, the cause of its expansion, its homogeneity on the large scale,
its flatness, etc., remain obscure; not to mention the time-break-off in
the finite past. In hope to avoid these difficulties, there has been introduced
a vacuum-like medium (E. Gliner, 1965). If initially our universe was vacuum-like,
under the phase transition of this medium to matter the latter is accelerated;
an expanding Friedmann universe arises as a result (E. Gliner & I.
Dymnikova, 1975). Some inflationary scenarios do not comply with this pattern
and can be in variance with GR. .
