Einstein's general theory of relativity gives rise to a far field gravitational force (gravito-radiative force) in addition to the Newtonian gravitational force which is a near field, just like Maxwell's theory gives a far field electro-magnetic radiative force in addition to the near field Coulombic and Lorentzian (magnetic) forces. The gravito-radiative force transmits energy and momentum from an accelerated gravitational source mass carried by gravitational waves. A violent collision between balack-holes at the center of a galaxy produces a gravito-radiative force by which some stars orbiting near the center are kicked out forming a pair of bars with a 180 degree rotational symmetry. The stars in these bars orbit around the galactic center maintaining the initial angular momentum given by the gravito-radiative force forming a pair of galactic spiral arms maintaining the 180 degree rotational symmetry.
