The redshift periodicity of galaxies as a probe of the correctness of general relativity

TL;DR

This paper investigates whether the observed periodicity in galaxy redshift distribution can validate or challenge general relativity by analyzing scalar field models and their coupling constants.

Contribution

It proposes using galaxy redshift periodicity as a probe to test the correctness of general relativity through scalar field coupling analysis.

Findings

Redshift periodicity can constrain scalar field coupling constants.

Observations may support or challenge the validity of general relativity.

The approach links galaxy data to fundamental gravitational theory.

Abstract

Recent theoretical work determines the correct coupling constant of a scalar field to the Ricci curvature of spacetime in general relativity. The periodicity in the redshift distribution of galaxies observed by Broadhurst {\em et al.}, if genuine, determines the coupling constant in the proposed scalar field models. As a result, these observations contain important information on the problem whether general relativity is the correct theory of gravity in the region of the universe at redshifts z<0.5.
