Does the Planck unit system relate to a non-singular primordial state of the universe?
(English)Manuscript (preprint) (Other academic)
Recently, a new model for flat-metric expansion of the universe that eliminates several problems arising in the expansion theory of standard cosmology was presented. In the original version of this dark source flux (DSF) model, Big Bang is manifested by a mathematical singularity with infinite initial matter density and infinite initial expansion rate. However, an integration constant (a time shift) with extremely small value was for simplicity set equal to zero in this theory. A closer analysis reveals that if this constant is assigned a very small nonzero value, Big Bang will not have started from a mathematical singularity, but from a primordial state of extremely high, yet limited density and expansion rate. This primordial state constitutes a non-singular Planck epoch of extremely short duration. It turns out that all primordial state parameters assume values of the order of Planck units. Thus, the Planck unit system may have found an attractive physical significance: it relates to the primordial Planck state of the universe where the three fundamental theories of physics merge.
There is a well known, puzzling ratio (of the order 10120) between ground state (‘vacuum’) density values based on quantum field theory on one hand, and experimental values derived from ΛCDM (or DSF) on the other. This discrepancy has been called the worst theoretical prediction in the history of science. The present article offers a possible explanation to this issue.
