Understanding the gravitational and cosmological redshifts as Doppler shifts by gravitational phase factors

From the viewpoint of gauge gravitational theories, the path dependent gravitational phase factors define the Lorentz transformations between the local inertial coordinate systems of different positions. With this point we show that the spectral shifts in the curved spacetime, such as the gravitational and cosmological redshifts, can be understood as Doppler shifts. All these shifts are interpreted in a unified way as being originated from the relative motion of the free falling observers instantaneously static with the wave source and the receiver respectively. The gravitational phase factor …

Doppler、引力与宇宙学红移

Doppler, gravitational and cosmological redshifts

针对Ortiz和Ibarra-Castor仅考虑能量守恒的红移公式，本文强调推导Doppler、引力与宇宙学三种红移需同时考虑能量与动量，并一致性地阐述了这三种物理效应及补充了相关文献。

Resolving Spacecraft Earth-Flyby Anomalies with Measured Light Speed Anisotropy

Doppler shift observations of spacecraft, such as Galileo, NEAR, Cassini, Rosetta and MESSENGER in earth flybys, have all revealed unexplained speed `anomalies' - that the doppler-shift determined speeds are inconsistent with expected speeds. Here it is shown that these speed anomalies are not real and are actually the result of using an incorrect relationship between the observed doppler shift and the speed of the spacecraft - a relationship based on the assumption that the speed of light is isotropic in all frames, i.e. invariant. Taking account of the repeatedly measured light-speed anisotr…

Combining NASA/JPL One-Way Optical-Fiber Light-Speed Data with Spacecraft Earth-Flyby Doppler-Shift Data to Characterise 3-Space Flow

We combine data from two high precision NASA/JPL experiments: (i) the one-way speed of light experiment using optical fibers: Krisher T.P., Maleki L., Lutes G.F., Primas L.E., Logan R.T., Anderson J.D. and Will C.M., Phys. Rev. D, vol 42, 731-734, 1990, and (ii) the spacecraft earth-flyby doppler shift data: Anderson J.D., Campbell J.K., Ekelund J.E., Ellis J. and Jordan J.F., Phys. Rev. Lett., vol 100, 091102, 2008, to give the solar-system galactic 3-space average speed of 486km/s in the direction RA=4.29hrs, Dec=-75.0deg. Turbulence effects (gravitational waves) are also evident. Data also …

A quantum description for charged fermions in strong gravitational field

The falling charge puzzle in gravitational field is well known due to the discussions of radiation. The puzzle lies in the heart of linking the electromagnetism and gravity. Up to date few discussions have fully taken account of quantum effect of a falling charged-fermion in strong gravitational field from the first principle. Based on the hypothesis that 4-dimension conformal symmetry may underly its dynamics, in this paper we try to establish a quantum equation for the falling process. The resultant equation provides a manner accounting for the strong CP violation at the beginning of the Big…
