Are black holes black?

Abstract

This work presents a resolution of the causality paradox formulated by T. D. Lee in the theory of the Unruh effect and in the theory of black holes. The basis of the resolution is to take into account the transformation of a pure state into a mixed state in a measurement, which leads to a corresponding modification of the Bogolyubov transformations, so that “black holes remain black.”
