Black Holes in Quantum Theories of Gravity
It is possible, in some theories of quantum gravity, to calculate the quantum corrections to ordinary, classical black holes. Contrarily to conventional black holes which are solutions of gravitational field equations of the general theory of relativity, quantum gravity black holes incorporate quantum gravity effects in the vicinity of the origin, where classically a curvature singularity occurs. According to the theory employed to model quantum gravity effects, there are different kinds of quantum gravity black holes, namely loop quantum black holes, noncommutative black holes, asympotically safe black holes. In these approaches black holes are singularity free.

“I put on
the body-armor of black rubber
the absurd flippers
the grave and awkward mask.”
—Adrienne Rich (b. 1929)
“Keyholes are the occasions of more sin and wickedness, than all other holes in this world put together.”
—Laurence Sterne (1713–1768)
“The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical.”
—Henry David Thoreau (1817–1862)
