Description/Abstract | A recent manuscript by Wright (1987) which purports to invalidate the chronometric cosmology by a comparison of its predictions with source counts is criticized.^The main observational problem with the manuscript is found to be its gross exaggeration of the statistical definitiveness of the rise in the radio source log N-log S slope above the Euclidean value and its failure to recognize the extreme complexity of radio source count interpretation.^Its statement that in the chronometric cosmology a source can appear bright by being close to the antipode where z = infinity is here stated to be false.^It is argued that Wright`s study ignores the statistics of the flux-redshift relation that is fundamental for testing theories as to the nature of the redshift, is based on the logically inconclusive question of the spatial distribution of sources, and indicates levels of significance derived by a posteriori reasoning, involving unrealistic assumptions.^21 references. |
