The simplicity of two dimensional nearly AdS$_2$ or dS$_2$ gravity and its connection to four dimensional physics.
After reviewing how certain black holes develop AdS$_2$ or dS$_2$ regions, we will describe some observables that are dominated by physics in these regions. Quantum gravity effects become relatively simple and calculable in this regime. We will describe various applications from wormholes to the computation of the Hartle-Hawking wave function for certain non-trivial topologies.
