My question is this: Does the direction of spin of a supermassive black hole exert an affect on the spin of its surrounding galaxy (given that the above described black hole is at the center of such a galaxy)? Is there a direct or correlative effect? If so, can an in-depth explanation be provided? Example: The supermassive black hole at the center of the Milky Way galaxy spins clockwise. Therefore, the Milky Way spins clockwise. Is this true/false, and why?
