Mackay et. al determined that propagation of negative phase velocity in this region is concentrated at the equator.
Mackay et. al determined that propagation of negative phase velocity in this region is concentrated at the equator. One hypothesis is that this region drives the production of jets according to the Blandford-Znajek mechanism. Within this region, objects must rotate in the direction of motion according to the Lense-Thirring effect. The static surface is located at its outermost region, while its inner boundary is the event horizon. A particle within this region cannot be motionless as viewed by an outside observer. The maximum radius of this region equals the Schwarzchild radius. This region was first defined by Kerr and is present in his namesake black holes. For 10 points, name this region of a black hole from which energy could be extracted according to Roger Penrose.
