Cumulative-Phase-Alteration of Galactic-Light Passing Through the Cosmic-Microwave-Background: A New Mechanism for Some Observed Spectral-Shifts

Abstract

Currently, whole of the measured "cosmological-red-shift" is interpreted as due to the "metric-expansion-of-space"; so for the required "closer-density" of the universe, we need twenty times more mass-energy than the visible baryonic-matter contained in the universe. This paper proposes a new mechanism, which can account for good percentage of the red-shift in the extra-galactic-light, greatly reducing the requirement of dark matter-energy. Also, this mechanism can cause a new kind of blue-shift reported here, and their observational evidences. These spectral-shifts are proposed to result due to cumulative phase-alteration of extra-galactic-light because of vector-addition of: (i) electric-field of extra-galactic-light and (ii) that of the cosmic-microwave-background (CMB). Since the center-frequency of CMB is much lower than extra-galactic-light, the cumulative-phase-alteration results in red-shift, observed as an additional contributor to the measured "cosmological red-shift"; and since the center-frequency of CMB is higher than the radio-frequency-signals used to measure velocity of space-probes like: Pioneer-10, Pioneer-11, Galileo and Ulysses, the cumulative-phase-alteration resulted in blue-shift, leading to the interpretation of deceleration of these space-probes. While the galactic-light experiences the red-shift, and the ranging-signals of the spaceprobes experience blue-shift, they are comparable in magnitude, providing a supportiveevidence for the new mechanism proposed here. More confirmative-experiments for this new mechanism are also proposed.
