Black Hole Information
arXiv:hep-th/9305040
Abstract
Hawking's 1974 calculation of thermal emission from a classical black hole led to his 1976 proposal that information may be lost from our universe as a pure quantum state collapses gravitationally into a black hole, which then evaporates completely into a mixed state of thermal radiation. Another possibility is that the information is not lost, but is stored in a remnant of the evaporating black hole. A third idea is that the information comes out in nonthermal correlations within the Hawking radiation, which would be expected to occur at too slow a rate, or be too spread out, to be revealed by any nonperturbative calculation.
48 pages, 292 references, LaTeX. Spaces were removed before reference abbreviations, so that citation numbers would be LaTeXed correctly by the current software, as the previous version of the paper had been by the old LaTeX software in use when that version was submitted. After Eq. (7), a new reference [290] was added, to Foong and Kanno's paper, which appeared after this review was published in the Proceedings of the 5th Canadian Conference on General Relativity and Relativistic Astrophysics
