# A"black hole theorem,"and its implications

@inproceedings{Giddings2021AblackHT, title={A"black hole theorem,"and its implications}, author={Steven B. Giddings}, year={2021} }

A “black hole theorem” is stated, exhibiting the basic conflict of the information problem. This is formulated in a more general context than that of quantum field theory on a background, and is based on describing a black hole as a quantum subsystem of a larger system, including its environment. As with the Coleman-Mandula theorem, the most important point is probably the loophole in the “theorem,” and what this tells us about the fundamental structure of quantum gravity. This “theorem” in…
