Mass of the Universe and the Redshift

摘要

Cosmological redshift is commonly attributed to the continuous expansion of the universe starting from the Big-Bang. However, expansion models require simplifying assumptions and multiple parameters to get acceptable fit to the observed data. Here we consider the redshift to be a hybrid of two effects: recession of distant galaxies due to expansion of the universe, and resistance to light propagation due to cosmic drag. The weight factor determining the contribution of the two effects is the only parameter that is needed to fit the observed data. The cosmic drag considered phenomenologically yields mass of the universe style="white-space:nowrap;">≈?2 × 1053 kg. This implicitly suggests that the mass of the whole universe is causing the cosmic drag. The databases of extragalactic objects containing redshift z and distance modulus style="white-space:nowrap;">μ of galaxies up to z = 8.26 resulted in an excellent fit to the model. Also, the weight factor w_D for expansion effect contribution to style="white-space:nowrap;">μ obtained from the data sets containing progressively higher values of style="white-space:nowrap;">μ?can be nicely fitted with src="Edit_8cccb1a1-b1ec-45b6-8f23-5ef8c212c25d.bmp" alt="" />.
