What can we do to understand singularities in gravitational collapse?
Bernard Whiting
University of Florida at Gainesville and Australian National University, Canberra
Abstract: The possibility of singularities in general relativity has been clear, if unpalatable, almost from its inception. But the unavoidability of collapse in a classical theory took more than 50 years to be clearly established, and was based on very specific, but conceptually broad, physical principles. Within a further decade, Hawking had completely inverted our perspective by showing that, semiclassically, collapse would lead to a quantum state with outgoing radiation at infinity. The same calculations, when extended to a black hole environment, showed that the physical principles, upon which singularity formation had rested, no longer held outside classical physics. This turnaround has left us in a state of perplexity ever since, and has added, besides, the unresolved entropy and remnant problems for an evaporating black hole. We will take look at where things stand today, and refer to possible hints at a way forward from here.
