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.

Famous quotes containing the words black, holes, quantum, theories and/or gravity:
“... the black woman can never forget—however lukewarm the party may to-day appear—that it was a Republican president who struck the manacles from her own wrists and gave the possibilities of manhood to her helpless little ones; and to her mind the Democratic Negro is a traitor and a time-server.”
—Anna Julia Cooper (1859–1964)
“But Father John went up,
And Father John went down;
And he wore small holes in his shoes,
And he wore large holes in his gown.”
—William Butler Yeats (1865–1939)
“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)
“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)
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
