Here is my view which is as much a guess as a guess can get
also applies to gravity. Its my TOE.
Your welcome to tear this down, and point out possible errors in my imagination.
We know atoms are hollow, it is a visual mind screw that object are solid to our 3 dimensional brains.
BH = black hole
I believe/imagine the atoms are broken down to electrons and protons and separated, not any smaller in a BH. I believe they are squished together causing the unknown reaction in the singularity. Basically the space has been removed and we have multiple small elements in different degrees depending on where they reside in the singularity. Elements meaning not matter as we know it, but still matter. An unknown atomic structure that is still an energy plant like a sun but on an extreme scale of gravity that changes atomic structures. Sun equals atoms still being able to hold their typical structure. BH meaning gravity so strong it has broken down atomic structure.
So take that and I address gravity as being created from the combination of dark matter/energy as being the fabric of our space, and that inside of atoms before they are broken down this fabric is naturally compressed, and in that when enough are compiled together we can measure the weak force. The weak force is cause by quantum entanglement, as when the fabric of space is compressed even if just slightly in an atom, pulls its counter parts of the fabric outside the atom towards the atom. The force so weak it Is not really measurable on its own. But with large masses of atoms this stretching of the fabric can be measured.
The reason a BH shows much more gravity then a sun is because as the space of the atoms has been reduced to nothing, the fabric of space is puled inwards exponentially. [if I worded that properly] then just compiled atoms.
Just my imagination.
