Cosmological Distance Scale. Part 11. “Extraordinary” Evidence and the “Cosmic Jerk” Problem

A statistical test of the “extraordinary” evidence for the “accelerated expansion of the Universe” owing to the “cosmic jerk” over a range of red shifts z = 0.46 ± 0.13 and for z = 0.763 based on data from SN Ia supernovae for which photometric distances have been determined is carried out. The transition from “deceleration” to “acceleration” is treated as a “disruption”– a change in the structure and parameters of the model for the cosmological distance scale. It is shown that the data from different sources do not form a compositionally uniform set. “Discrepancies” in the model for the scale are discovered for z = 0.44–0.48 in a sample of 10 SN Ia over an interval from z = 0.30–0.97 according to data from the High-Z Supernovae Search Team and for red shifts z = 0.763–0.828 in a sample of 42 SN Ia over an interval from z = 0.172–0.83 according to data from the Supernovae Cosmology Project. The reason for these “discrepancies” may be an unbalanced and random distribution of the SN Ia over the observed range of red shifts for a scale with a clearly distinct non-metric character.
