Query: Torsion and gravitational interaction in Riemann-Cartan space-time   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.
