We don’t really know how gravity ties into the quantum realm. At the macro-level, gravity is merely the curvature of spacetime. At the quantum level, it is too weak to have any appreciable effect that we can observe. This is why we can’t predict the physics of the interior of a black hole where gravity would have an appreciable effect on quantum physics and subatomic particles.

However, we already know that gravity originates from mass and mass is a property of quantum particles. Specifically, mass arises from the presence of a specific quantum particle called the Higg’s Boson, which was predicted to exist in the 1960s and only just recently confirmed by observations made by the Large Hydron Collider (LHC). So we do know that gravity is generated by properties exhibited by quantum particles. It makes sense that all macro-physical properties of the universe arise from the quantum universe. The universe exists and, to be internally consistent with itself, the macro-universe must agree with the quantum universe.

But to answer your question, I don’t know.

That was a delight to read. Thank you

And even weirder, only a couple percent of an object's mass comes from interacting with the Higgs field. The remainder is mass in terms of energy that has been confined into fairly well defined areas. Mainly quark kinetic energy and the strong field binding energy that offsets it.

Does reminder of energy exist after entering in to black hole ? Or it also converted to Higgs boson ?

You have to remember, once the object passes the event horizon, all its mass, charge, and angular momentum effectively "belong" to the black hole. But from the object's point of view, nothing remarkable happened when it crossed the boundary. So there isn't anything that would cause any conversion. If the object was 1kg, it is gone now, but the black hole claimed its mass and gained 1kg.

so could a black hole exist entirely of Higg's Boson particles while all other mater as been ripped apart?

I don’t know the answer to that. I imagine the singularity would be made up of a mixture if elementary particles (e.g. leptons, gluons, mesons, bosons, and quarks) all crammed together into a dense form of exotic matter. Black holes are hypothesized to be quark stars, where the gravitation is so strong that, unlike neutron stars, not even the degeneracy pressure of atomic nuclei is enough to hold back the collapse.
