Can a black hole avoid becoming a singularity?

Could a black hole be held up from collapse to a singularity by the unified force?

As a black hole collapses, it becomes hotter and hotter. Wouldn't it eventually become so hot that the unification temperature for all four forces is reached and the gravity within the core of the black hole ceases to be gravity as we know it? The lack of gravity may cause the hole to stop collapsing and begin to expand. This expansion causes the hole to cool and gravity reenters the picture when it breaks off from the hyperweak force. This causes it to begin collapse again. This repeats until an equilibrium or quasi-equilibrium is reached and the core retains a fairly constant radius. A finite radius. Larger than zero. If the core is below the Schwarzchild radius (and I imagine it would be, given how much it would have to collapse to reach these amazingly high temperatures), then it would look like a classical "singularity model" black hole because it would still have an event horizon. The horizon would also keep heat from escaping the black hole to allow it to collapse all the way to a singularity.

This depends much on the behavior of the unified force, of course. Are there any predicted properties of the force? If it is a purely attractive force, then we can throw this idea out of the window. If it is repulsive, or simply a non-directional sort of thing (sort of like the weak nuclear force), then this scenario might play out.

Any thoughts? This is speculation, of course.

I am not sure how much is known about the intersection of that part of GR which predicts a singularity and that part of the Standard model that governs super high energy unification and degeneracy.  We just do not really know too much about neutron degeneracy (when gravity is strong enough to force inverse beta decay) even less about quark degeneracy (proposed state under even higher gravity when neutrons split to constituent up/down quarks) - and the next stage is guess work.  Regarding the unification of the forces - again it is fun but ultimately unrewarding to guess as so little is actually known. 

In all empirical physics the black hole is the event horizon - there is a complete separation between inside and outside, unknown and unknowable with present axioms.  Not to say we should not speculate - but it is not testable and thus unfalsifiable, and that's a big no no

The question might be how 'hot' that mass becomes as it compress. Assuming a infinite compression at the centre it seems reasonable to assume a infinite 'heat'. That should mean that the energies produced there will be infinite too. A reversed Big Bang :) but under our arrow
