Abstract

Currently the present-time value of the Hubble constant is estimated through finding the optimum fit to the observationally measured data. Here, assuming a flat universe with zero cosmological constant, based on the conservation of total mass-energy and a correction for the effect of time dilation, the total present-time value of the energy density parameter is found to be equal to 0.703091. Based on the Friedmann-Robertson-Walker (FRW) equation, the first law of thermodynamics, and Einstein’s Equivalence Principle, we present an analytical approach which yields a value for the Hubble constant equal to H_0=69.05398 km s^(-1) 〖Mpc〗^(-1). Using this value, Hubble diagrams are constructed. These diagrams are remarkably consistent with the available observational data.
