Abstract ‘Black Holes and the Edge of Physics’ delves into the mysteries of black holes, and shows how these enigmatic objects may transcend quantum physics. We begin with a review of how black holes form and eventually evaporate, resulting in the notorious problem of ‘information loss’. We show how pilot-wave theory could solve the problem by allowing information to escape at superluminal speeds. We describe an experiment that could test these and related ideas, involving astrophysical black holes in space. The chapter ends with an account of the life cycle of black holes and the role they may play in ‘reprocessing’ our quantum universe.

We study a proposal for the resolution of the black hole information puzzle within the context of modified versions of quantum theory involving spontaneous reduction of the quantum state. The theories of this kind, which were developed in order to address the so-called measurement problem in quantum theory have, in the past, been framed in a nonrelativistic setting and in that form they were previously applied to the black hole information problem. Here, and for the first time, we show in a simple toy model, a treatment of the problem within a fully relativistic setting. We also discuss the issues that the present analysis leaves as open problems to be dealt with in future refinements of the present approach.
