Abstract

I summarize experimental and theoretical constraints on gravity theories. I explore metric f(R) gravity, and explore scalar field theory analogs. I present a different kind of mechanism to raise the effective scalar mass in f(R) gravity in environments with particular ranges of background scalar curvatures, and thus suppress scalar effects on solar system curvature scales, while allowing scalar effects at different curvature scales. I review the post-Newtonian and post-Minkowskian mathematical machinery for General Relativity, and generalize these expansions to metric f(R) gravity up to second order in small parameters.
