Hi ScientificSorcerer
There is probably something at the center of the blackhole, maybe a quark-gluon fluid or whatever. However, light stays inside the BH because of its gravitationnal field. The source of the gravitationnal field could be anything.
Also, at the horizon of a large BH, like a galactic BH, the gravitationnal field is in fact low and space is flat at the horizon. Anything that falls in the large BH would see nothing special happening, it wouldn't even know it's inside a BH.
I don't know what would happen at the center but things may change however because the gravitationnal field would be huge there, which would possibly desintegrate the small BH.
We can speculate on what happens at the center but it's really speculative because we don't have a good theory of quantum gravity.
I was talking about such things in another thread above yours, called "Big bang and first law of thermodynamics" you might find my theory on the subject enlightening. As for your question about black holes, yes the small black hole remains intact as it merges with a bigger black hole. This is because of the "state of matter" that black holes are in. you see black holes are in a 5th state of matter called the bose-einstine condensate (bec) In which the empty space of atoms is turned into 0% this is because of the way gravity pushes the nuclei of atoms together so much that the force of gravity overcomes the electromagnetic repulsion force of the electron cloud. when black-holes merge the state of matter that they are in doesn't change, the small black hole just adds it's clump of atoms in the BEC state to the larger black hole's atoms in the BEC state.
the light trapped in the BEC still can't escape because the "state of matter" hasn't changed.
