In this talk I will explain how certain aspects of black-hole physics can be understood using ideas from effective field theory. Many of the familiar notions from particle physics will play a role, including the renormalization group, universality and naturalness. In particular, I will explain why black holes naively seem like fine-tuned systems, but they are ultimately not thanks to a accidental symmetry of General Relativity.
