One possible fate of information lost to black holes is its preservation in black hole remnants. It is argued that a type of effective field theory describes such remnants (generically referred to as informons). The general structure of such a theory is investigated and the infinite pair production problem is revisited. A toy model for remnants clarifies some of the basic issues; in particular, infinite remnant production is not suppressed simply by the large internal volumes as proposed in…

White holes as remnants: a surprising scenario for the end of a black hole

Quantum tunneling of a black hole into a white hole provides a model for the full life cycle of a black hole. The white hole acts as a long-lived remnant, providing a possible resolution to the…

It is argued that couplings in Reissner-Nordstroem black holes as a paradigm for a theory of remnants may give finite production despite an infinite spectrum, and naive arguments for infinite production fail.

The possibility of stable or quasi-stable Planck mass black hole remnants as solution to the black hole information paradox is commonly believed phenomenologically unacceptable. Since we need a black…

It is argued that the rate is proportional to the thermodynamic quantity Tr e-H, where the trace is over the internal states of a black hole; this is in agreement with estimates from an effective field theory for black holes.
