Well, there’s the hypothesis of a “naked singularity” whereas if enough charge or spin could be added to a black hole, the event horizon, aka, the black part of a black hole, could just vanish. This would expose the singularity at its center but its just a hypothesis. Or better yet, a thought experiment at best. This wouldn’t eliminate its mass though.
Does this also mean that black holes are totally indestructible?
Basically.
They slowly decay as hawking radiation, but there’s nothing you can do to speed up the process.
