the situation of the Kerr black-hole uniqueness proofs, since in these proofs very strong symmetry requirements are made, which are inconsistent with the generic condition: The generators of the Kerr event horizon, for example, never feel tidal forces. However, the black-hole uniqueness theorems are frequently used to argue that the final black-hole state is of Kerr type; the symmetry requirements are then not expected to hold exactly for all time, just approximately in the limit of a long time after the black hole formation. In this actual physical case the generic condition does hold, for the reasons given on page 101 of HE. Thus Theorem 2 tells us that although there may be nonsingular causality-violating black-hole solutions, they would have to satisfy strong symmetry requirements exactly over their entire history. In other words, the existence of CTL would be an unstable property of black holes. Hence, no physically realistic, causality-violating, nonsingular black-hole solutions exist.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
