> What's a black hole without a singularity? A black hole with a lumpy interior. (It does not have to be always lumpy). Consider two black holes of the type you envisage, where the mass and charge of each is entirely at the singularity point of each black hole. Let the black holes merge. How do two singularities become one singularity?
