Abstract: The influence of the Coriolis inertial force, generated by orbital and spin motions of distant objects, on the energies of electromagnetic radiation during the exchange of photons between them is shown. The presence of a red or blue spectral shift arising from this influence has been demonstrated, which is fully consistent [...] Read more.
