Relativity and Cosmology


Apparent Time-Dependence of the Hubble Constant Deduced from the Observed Hubble Velocity-Distance Equation

Authors: Feng Xu

An apparent time dependence of the Hubble constant was deduced from the linear correlation between the recession velocity of galaxies and the traveled distance of their photons under the assumption of the space expansion being homologous. The time dependence of the space expansion velocity at early era implied that the currently used relativistic Doppler equation, invalid for accelerating/deaccelerating reference frames, would lead to inaccurate measurement of the cosmological recession velocity for highly redshifted galaxies/quasars.
