Abstract

We prove the Penrose-Wall singularity theorem in the full semiclassical gravity regime, significantly expanding its range of validity. To accomplish this, we modify the definition of quantum-trapped surfaces without affecting their genericity. Our theorem excludes controlled “bounces” in the interior of a black hole and in a large class of cosmologies.

  14. It is difficult to think of any other regime in which a bounce could be operationally established. Note that causal structure would have to be preserved in order to transmit information through a bounce and thus make the bounce verifiable. But then the GSL is applicable across the bounce and the contradiction established in our theorem still excludes the bounce.
