Abstract

This thesis discusses the philosophy behind models of quantum black holes in AdS/CFT. These models display a variety of foundationally and metaphysically interesting features, ranging from modifications to the semiclassical structure of spacetime, to wide-ranging impacts on the metaphysics of laws of nature and the nature of spacetime emergence in Quantum Gravity.

In particular, on the philosophy of physics side in this thesis I discuss the relation between AdS/CFT constructions introducing certain non-local connections within the spacetime structure of General Relativity and the topic of causality conditions on evaporating black holes in General Relativity. On the metaphysics side, I use AdS/CFT to illustrate how Humeanism can be articulated in Quantum Gravity. I also argue that in AdS/CFT, black holes make standard approaches to spacetime emergence untenable. Finally, I argue that in AdS/CFT we should prefer a Humean metaphysics in regard to laws of nature.
