After the publication of Calogero's original paper, "[The] [c]osmic origin of quantization" a response was published by Giuseppe Gaeta of the University of Rome in which he discussed the compatibility of the conjecture with present bounds on variation of fundamental constants, but also outlined his focus on the modification of the relation between redshift and distance, and of the estimations attained from observations of elapsed time from the production of cosmic radiation and implications —both being related also, to the observed blackbody distribution of background cosmic radiation.
