NEW PERSPECTIVE, “While the transition to the white hole is still assumed to be on a spacelike hypersurface at a minimum circumferential radius r = a separating the trapped surfaces in the interior of the black hole from the anti-trapped 2-surfaces in the interior of the white hole, I consider alternative scenarios for evolution of the white hole, in which the white hole only emits negative energy for a limited Planck-scale range of retarded time.”
