Potential observable consequences at astrophysical scales

Abstract

The influence of space-time torsion on gravitational interaction at cosmological and astrophysical scales is discussed within the framework of gauge gravitation theory in Riemann-Cartan space-time. It is shown that the interaction of the vacuum torsion with proper angular momentums of gravitating objects leads to appearance of additional gravitational force which can be manifested at astrophysical scale.
