An Alternative Approach of the Dark Energy Beyond the Equation of State

Abstract

Several concepts have been proposed to explain the mystic nature of dark energy and the accelerating universe. Among them, geometrical dark energy is one such class that is based on the scalar curvature, and another type is based upon the “equation of state”. Also, another model suggests that neutrino rest-mass interaction is responsible for the “equation of state” with constant energy density. In this work, we have investigated another dark energy approach which is based on the illusive mass of the photon and a new geometrical perspective. Photon reveals its illusive mass behavior when it interacts with the surface of matter, i.e., photon manifests itself into different forms of mass. Hence, photon might hide some of its energy due to this new characteristic. This photon’s energy is embedded in the form of a curvature dependent complex number and could be considered as the new form of dark energy. Hence, we propose that the dark energy might be hiding in the photon’s illusive form and could pave the way towards unravelling the secrets of the dark energy of the universe and hence the accelerating universe.
