Einstein's refinement of Newtonian gravitation repeated for General Relativity (GR) by quantum cosmology requires inflationary models of the universe to be critically reevaluated; the Hubble redshift is shown not to result from Doppler velocity, but anisotropic coupling to vacuum zero point fluctuations through harmonic structure described in terms of the Wheeler -Feynman absorber theory of radiation in the context of a Dirac vacuum and compactification dynamics. The quantum gravity of the comoving hyperstructure of a universe topologically both open and closed like a Klein bottle, also implies that frequency shift in photon propagation over cosmological distances is an inherent part of the spin exchange process, removing the ad hoc criticism of the well known Vigier theory of 'tired light'.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
