  We argue that the infall time to the singularity in the interior of a black
hole, is always related to a classical thermalization time. This indicates that
singularities are related to the equilibration of infalling objects with the
microstates of the black hole, but only in the sense of classical
equilibration. When the singularity is reached, the quantum state of the black
hole, initially a tensor product of the state of the infalling object and that
of the black hole, is not yet a "generic" state in the enlarged Hilbert space,
so its complexity is not maximal. We relate these observations to the
phenomenon of mirages in the membrane paradigm description of the black hole
horizon and to the shrinking of the area of causal diamonds inside the black
hole. The observations are universal and we argue that they give a clue to the
nature of the underlying quantum theory of black holes in all types of
asymptotic space-times.
