Black Holes in Quantum Gravity
The no-hair theorem is formulated in the classical spacetime of Einstein's general relativity, assumed to be infinitely divisible with no limiting short-range structure or short-range correlations. In such a model, each possible macroscopically-defined classical black hole corresponds to an infinite density of microstates, each of which can be chosen as similar as desired to any of the others (hence the loss of information).

Famous quotes containing the words black holes, black, holes, quantum and/or gravity:
“The shadow of the Venetian blind on the painted wall,
Shadows of the snake-plant and cacti, the plaster animals,
Focus the tragic melancholy of the bright stare
Into nowhere, a hole like the black holes in space.”
—John Ashbery (b. 1927)
“You can’t be what you don’t see. I didn’t think about being a doctor. I didn’t even think about being a clerk in a store—I’d never seen a black clerk in a clothing store.”
—Joycelyn Elders (b. 1933)
“A person taking stock in middle age is like an artist or composer looking at an unfinished work; but whereas the composer and the painter can erase some of their past efforts, we cannot. We are stuck with what we have lived through. The trick is to finish it with a sense of design and a flourish rather than to patch up the holes or merely to add new patches to it.”
—Harry S. Broudy (b. 1905)
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
