Abstract
I show that spin-spin contact interactions occur in a quantum version of Einstein's conventional theory, which are of the same order of magnitude as those occurring in Einstein-Cartan-Sciama-Kibble (ECSK) theory. Thus, all the features which were thought to be peculiar to the ECSK theory—singularity behavior, possibility of stopping gravitational collapse, and so on—actually occur in Einstein's theory. In addition, I examine a contact term (independent of spin orientations and analogous to the Darwin term of quantum electrodynamics) which always gives rise to repulsive gravitation forces.This publication has 16 references indexed in Scilit:
