The formula for the Bekenstein–Hawking entropy ( S) of a black hole, which depends on the area of the black hole ( A ). The constants are the speed of light ( c ), the Boltzmann constant ( k ), Newton's constant ( G ), and the reduced Planck constant ( ħ ). In Planck units, this reduces to S = A 4. See more A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. The theory of general relativity predicts that a sufficiently compact See more The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent … See more By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists searching for black holes must generally rely on indirect observations. For example, a black hole's existence can … See more Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any … See more The idea of a body so big that even light could not escape was briefly proposed by English astronomical pioneer and clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same … See more Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether they were merely pathological solutions to Einstein's equations. Einstein himself wrongly thought black holes would not form, because … See more The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star. The size of this limit heavily depends on the assumptions made about the properties of dense matter. New exotic phases of matter could … See more

WebMay 13, 2024 · The first so-called numerical relativity solutions to the Einstein equations for the case of a black hole merger were calculated only in 2005 — after decades of attempts. They required a supercomputer running on and off for two months. A gravitational wave observatory like LIGO needs to have a large number of solutions to draw upon.
WebThe quest to understand the quantum aspects of gravity has a long history.
