Just a note about my major annoyance with black hole discussions:
Accepting there are singularities within the event horizon as a foregone conclusion derived under a non applicable physics model annoys me immensely.
Under relativity nothing stops matter, energy and spacetime from being crushed into a singularity within the event horizon, but its pretty clear relativity doesn't apply within this framework - so why apply its dictates at all?
Model what can happen under quantum mechanics, quantum gravity, loop quantum gravity, SuSy etc
Treat three (?) dimensional space, one dimensional time (?), the equivalance that are matter and energy, which affect properties of both the shape of spacetime and the rate that time passes at a given locale within said spacetime as complex interrelated variable and come up with a scenario that works.
As it stands this singularity as a foregone conclusion is really sloppy science from my perspective. I'd rather it be called X and unknown and try and model it out.
Even the work on massive grav-stars showed if during collapse your sun had massive spin (angular momentum) then a singularity could be avoided.
Personally I think you're going to end up with some pretty wierd, interdependent framework as all the variables interact with one another so they are all kinda self referential. Think about it mass is meaningless without time and space to exist within. Same goes for energy. But energy and mass shape both space and time so they must be able to both move within it, and shape or change it as they move. Mass and energy must interact with both each other and time and space. We still can't model what happens with these interactions when one or more of these properties gets either really big, really small, really heavy, really energetic. At a quantum level all our sciences break down and we need a way of fixing this before we talk about what happens in this domain.
So lets be crystal clear - the four forces affecting matter and energy (gravity, electomagnetism, strong nuclear, weak nuclear) - don't interact clearly in any sort of describable, sensible fashion once you get down to distances that are the size of an atom or smaller! All our powerful, modern physics breaksdown at this level and you really do have to transition to the very wierd and incompletely understood world of quantum mechanics (things appearing, dissappearing, tunnelling, being in more then one place at one time, not always absolutely conserving mass nor energy, not every having a specific location, inbuilt uncertainity dominating their actions, never being at absolute rest etc ... acting probablistically) to model reality. Until we better understand the interactions between all the dynamic changes to the geometry of spacetime and things within it at both the nano and macro scales - our physics and understanding of reality is very incomplete.
My brain is full, can I go home now sir?
