Hi all, I've been wondering:
Thinking of Arthur Eddington's relativistic oriented 1919 eclipse observation, would the photon deviation due to the Sun's gravitational imposition have caused the photons to exhibit a qualitative redshift due to the time photons had spent within the Sun's gravitational influence? When the photons reached the Earth, would a spectrometer or somesuch device discern a qualitative redshift difference on the photons that would be different from when the Sun was not an influence?
Any knowledge, opinions welcomed.
