Black hole - Wikipedia

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 mass can deform spacetime to form a black hole. The boundary of … 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 … 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 … 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 The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent physical properties: mass, electric charge, and angular momentum; the black hole is otherwise featureless. If the conjecture is … See more By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists … See more Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any … See more • Binary black hole • Black brane or Black string • Black Hole Initiative • Black hole starship See more WebMay 13, 2024 · For the first time, astronomers have captured an image of the supermassive black hole at the center of our Milky Way galaxy, confirming the presence of the cosmic … WebThere are four types of black holes: stellar, intermediate, supermassive, and miniature.
