Gravitation theory in multimessenger astronomy II: crucial observational tests based on GW and optical observations Yu.V. Baryshev, S.A. Oschepkov

Abstract

     Multimessenger astronomy provides crucial observational tests of gravity physics for two alternative theories of gravitation – Einstein's geometrical General Relativity Theory (GRT) and Feynman's non-metric field gravitation theory (FGT), which we considered in the first report. Such tests are able to clarify the key question on the nature of gravitational interaction: is gravity the curvature of space? or is gravity a material field in Minkowski flat space as other physical forces? Up to now all actually performed experiments/observations do not allow to distinguish between these two alternatives in gravity physics, however forthcoming multimessenger astronomy will bring the answer to this fundamental question.
