Yep. The big unanswered question as far as I know (from a layman's perspective) is whether the matter/energy in the singularity at the center of a black hole even follows the laws of nature as we have observe them or if all of that is out of the window past the event horizon. If you don't know the laws of nature describing what happens inside (and you can't study them due to the destructive nature of those forces), no amount of computation will be able to help.
