TLDR
Theoretically, the center of a black hole is occupied by an ultra-dense, spheroidal core whose diameter is greater than that of the theoretical disk singularity as mentioned in this paper.Abstract:
Growth of a black hole requires the participation of a near-by accretion disk if it is to occur at a significant rate. The Kerr solution of Einstein’s equation is a vacuum solution, but the center of a realistic Kerr black hole is not a vacuum, so the predicted disk singularity does not exist. Instead, the center of a black hole is occupied by an ultra-dense, spheroidal core whose diameter is greater than that of the theoretical disk singularity. The surface of a black hole’s core is continually bombarded by energetic particles from the external universe. Hence the cold remnant of a gravitationally-collapsed star that has often been assumed to be present at the center of a black hole must be replaced conceptually by a quark-gluon plasma whose temperature is of the order of 1012 K or more. The gravitational potential well of a black hole is extremely deep (TeV), but the number of discrete energy levels below the infinite-red-shift surface is finite. Information can be conveyed to observers in the external universe by thermally-excited fermions that escape from levels near the top of a black hole potential well.read more

TL;DR: These two neutrino-induced events could be a first indication of an astrophysical neutrinos flux; the moderate significance, however, does not permit a definitive conclusion at this time.

Discreteness of space from the generalized uncertainty principle
TL;DR: In this article, a Generalized Uncertainty Principle (GUP) consistent with string theory, Doubly Special Relativity and black hole physics was proposed, and it was shown that this can predict an upper bound on the quantum gravity parameter in the GUP, from current observations.

Discreteness of space from GUP II: Relativistic wave equations
TL;DR: In this paper, the Generalized Uncertainty Principle (GUP) was applied to a particle in a one-dimensional box and it was shown that the box length must be quantized in terms of a fundamental length, which could be interpreted as a signal of fundamental discreteness of space itself.
