If black holes leave empty spacetime after they evaporate, the information about quantum matter forming black hole is lost. This is the celebrated information paradox originally stated by Hawking. Researchers focus on some aspects of the relation of spacetime and quantum mechanics and the study counterparts (in Set) of the categorical local symmetries of smooth 4-manifolds. In the set-theoretic limit, there emerge some exotic smoothness structures on  R 4 (hence the Riemannian nonvanishing curvature), which fit well with the quantum mechanical lattice of projections on infinite-dimensional Hilbert spaces.
