Quantum_Conundrum
At the moment the critical density is acheived and a star begins collapsing into a black hole, what happens to the force fields for the Strong and Weak Nuclear forces which are still left over in the remaining neutrons and stray atoms just before?

Clearly, the force fields do not "disappear," after all, gravity and electromagnetism overcome one another in ordinary situations all the time, especially with human invention, yet neither field necessarily disappears. I still have some permanent magnets self-levitating after two years, for example.


Shouldn't there be some sort of "nuclear force halo" created when all of the neutrons are crushed into a single particle? This would seem to prevent the formation of microscopic black holes, except by some sort of absurd quantum fluctuation, i.e. a trillion kilograms of matter being created all at the same point spontaneously or something like that, which would seem more absurd than most any other theoretical device in science.

Or is the nuclear force simply converted to pure "rest mass" in the black hole?

Well, nobody ever explains what happens to this energy once the weight of the star's mass overwhelms the nuclear force.

In a black hole, the energy would seem to not be able to escape either way, but it must still be there in some form, and there seems to be no good reason it shouldn't remain as a sub-atomic field.

For example, in the instant the first two neutrons at the very core of a collapsing neutron star are smashed into one another, becoming a microscopic super-particle, shouldn't it have roughly twice the nuclear force of either of the original neutrons, and thereby be twice as resistant to future particle mergers as the original neutrons?

All the 'particles' of matter are currently believed by most physicists as real objects. But in my opinion, 'particles' of 'matter' are a 'process' or a 'phenomenon' of fluctuations or vibrations spontaneously sprung in some still-more-fundamental-reality. Energy and matter are the dynamic-aspect of that fundamental-reality. This is the reason why all short-lived-particles generated in the 'accelerators' decay into some other particles. This is the reason why a pair of electron-and-positron annihilate into a pair of photons. So, the belief that all matter and fields get compressed to 'singularity' in a 'black-hole' can not be correct. At some point a black-hole must start evaporating, radiating-out all the energy it possessed.

Physicists are trying to solve the problem of "What is 'matter' and what are its interactions?"
And the statement: "All the 'particles' of 'matter' are a 'process' or a 'phenomenon' of fluctuations or vibrations spontaneously sprung in some still-more-fundamental-reality. Energy and matter are the dynamic-aspect of that fundamental-reality." is like an answer printed in the last pages of mathematics-text-book.

Wiki here say: A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.[1] The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.[2][3] Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Sure.
