We construct an infinite family of microstates with geometric interiors for eternal black holes in general relativity negative cosmological constant any dimension. Wormholes the Euclidean path integral gravity cause these states to have small, but non-zero, quantum mechanical overlaps that a universal form. The dramatic consequence: span Hilbert space log dimension equal Bekenstein-Hawking entropy. semiclassical we contain Einstein-Rosen bridges arbitrary size behind their horizons. Our results imply all can be interpreted as superpositions wormholes at most exponential
