Screening and Absorption of Gravitation in Pre-Relativistic and Relativistic Theories

Abstract

Abstract. After commenting on the early search for a mechanism explaining the Newtonian action-at-a-distance gravitational law we review nonNewtonian effects occurring in certain ansatzes for shielding, screening and absorption effects in pre-relativistic theories of gravity. Mainly under the aspect of absorption and suppression (or amplification), we then consider some implications of these ansatzes for relativistic theories of gravity and discuss successes and problems in establishing a general framework for a comparison of alternative relativistic theories of gravity. We examine relativistic representatives of theories with absorption and suppression (or amplification) effects, such as fourth-order theories, tetrad theories and the Einstein-Cartan-Kibble-Sciama theory.
