Lack of Cosmological Expansion Versus the Hubble Crisis

Authors: Michael A. Ivanov

Based on the low-energy quantum gravity model, it is shown that the overestimation of the Hubble constant at small z, characteristic of the cosmological model, can be eliminated using a two-parameter luminosity distance function that takes into account the change in the number of photons. This new function was fitted to a similar function in the model, which best describes observations. Estimates were obtained for the light attenuation parameter, which replaces the effect of dark energy, and for the Hubble constant in the new model without cosmological expansion. Such a resolution of the Hubble crisis could cause a serious conceptual crisis in modern cosmology.
