Abstract

We consider the evaporation of the (shell-focusing) naked singularity formed during the self-similar collapse of a marginally bound inhomogeneous dust cloud, in the geometric optics approximation. We show that, neglecting the back reaction of the space-time, the radiation on I+tends to infinity as the Cauchy horizon is approached. Twoconsequences can be expected from this result: (a) the back reaction of space-time will be large and eventually halt the formation of a naked singularity thus preserving the Cosmic Censorship Hypothesis, and (b) matter attempting to collapse into a naked singularity will radiate away energy at an intense rate, thereby possibly providing experimental signatures of quantum effects in curved space-times.

    This leaves just the first option, that the Hawking radiation is pure. In 1993, Susskind et al. [7], building on the work of 't Hooft [8] and Preskill [9], proposed that the unitarity of the Hawking radiation could be preserved if information is both emitted at the horizon and passes through it, so an observer outside would see it in the Hawking radiation and an observer who falls into the black hole would see it inside but no single observer would be able to confirm both pictures. Although there is no precise mechanism by which it can be said to occur, thought experiments that appear to support this picture of “Black Hole Complementarity” rely on three fundamental assumptions, viz., (a) the unitarity of the Hawking radiation, (b) the validity of effective field theory outside a “stretched” horizon and (c) the equivalence principle.
