Quantum Physics of Black Holesnditions). In quantum theory, negative energy density may arise in a region of space because an external field applied to the vacuum may either increase or reduce the local energy density of zero point fluctuations. It is this phenomenon, known as ., that is to be expected to play an important role in the neighborhood of black holes.

Die Durchdringungslinien von Vielflachenr to answer these questions, the definition must first of all be extended to the general case of non-stationary spacetime. This generalization is obvious. It is reasonable to define the . in general as the region of spacetime from which no information-carrying signals are allowed to escape to a distant observer.

Die Durchdringungslinien von Vielflacheniscussed two examples of such processes; namely, the Penrose process (Section 6.2.3) and superradiance (Section 4.8.2). In this section, we establish some general restrictions on the possible efficiency of this kind of process.

This property is directly connected with the non-trivial causal structure of spacetime in the presence of a black hole
