The Newtonian and general relativistic equations for radial motion in the field of a central massive object are identical, and have the property that particles infalling from rest at infinity, and black hole “wind” particles with relativistic velocity leaking out of a Schwarzschild-like black hole nominal horizon, both have the same magnitude of velocity at any radius from the hole. Hence when equally massive infalling and wind particles collide at any radius, they yield collision products with zero center of mass velocity, which can then nucleate star formation at the collision radius. We suggest that this gives a general mechanism by which a central black hole can catalyze galaxy formation.
