Specifically, in this work he has applied geometric structures similar to those of a crystal or graphene layer, not typically used to describe
black holes, since these geometries
better match what happens inside a
black hole: «Just
as crystals have imperfections in their microscopic structure, the central region of a
black hole can be interpreted
as an anomaly in space - time, which requires new geometric elements in order to be able to describe them more precisely.

black hole and in fact it is not very
well known, but that energy is there for the taking — up to 29 percent of the so - called rest mass energy of a spinning
black hole is extractable — an d original conjecture, which is not,
as I say [said], yet established fact, but certainly taken much more seriously than it was at that time — 10 or 15 percent of the rest mass energy of the
black hole, about half of the spin energy, is in practice according to our conjecture, is in fact, the power source for these relativistically moving jets.
