Recognized wisdom suggests that when an object collapses behind its event horizon the objects in orbit will experience no change in force. I am putting together a mathematical model to show this is not the case. Initially I had thought that the gravitation would be amplified. However, initial work shows that the force of gravity will reduce. This results in a drift of objects away from the central black hole. This will result in longer more extended orbits around the central mass. Rather than the black hole clearing the centre by consuming mass the galactic masses drift outward to settle into larger and slower orbits. This explains why we have an empty region around black holes.
