Definition of black hole in English English dictionary: A gravitationally domineering celestial body with an event horizon from which even light cannot escape; the most dense material in the universe, condensed into a singularity, usually formed by a collapsing massive star; A sphere of influence into which or from which communication or similar activity is precluded
you'll have to love U.S. District Court Judge John Kane's decision to keep Denver-based Exactis.com out of an Internet black hole.... MAPS maintains a database of Internet addresses that it believes send or relay spam. It’s called the Realtime Blackhole List.; An entity which consumes time or resources without demonstrable utility
I finished some client work and gave myself 30 minutes to fall down one of my favorite internet black holes: genealogical research. Four hours plus some later, my eyes were burning in my head.; caused by the death of an extremely large star, black holes have gravitational fields strong enough to trap light Black holes consist of a singularity, the center where all the mass resides, and an event horizon, a black disk encircling the singularity and the point at which light can no longer escape the gravitational forces of the black hole; a region of space resulting from the collapse of a star; extremely high gravitational field; An object so dense that light cannot escape from it; Area in space where matter is so densely packed that the gravitational field produced permits nothing to leave, not even light [Image]; {i} theoretical space object which has an extremely strong gravitational force; dungeon; The configuration of a massive star that has undergone gravitational collapse, in which gravitation at the surface is so intense that even the star's own light cannot escape; A star which has collapsed on itself because of its extremely large gravitational force from which not even light can escape; A region of space surrounding a very massive collapsed star, or "collapsar" from which not even light can escape; An object with such high gravity that not even light can escape These may be formed when the most massive of stars die, and their cores collapse into a superdense mass; A region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull; Black holes are areas in space, where gravity is so strong that nothing, not even light, can escape from them. Black holes are thought to be formed by collapsed stars. Cosmic body with gravity (see gravitation) so intense that nothing, not even light, can escape. It is suspected to form in the death and collapse of a star that has retained at least three times the Sun's mass. Stars with less mass evolve into white dwarf stars or neutron stars. Details of a black hole's structure are calculated from Albert Einstein's general theory of relativity: a "singularity" of zero volume and infinite density pulls in all matter and energy that comes within an event horizon, defined by the Schwarzschild radius, around it. Black holes cannot be observed directly because they are small and emit no light. However, their enormous gravitational fields affect nearby matter, which is drawn in and emits X rays as it collides at high speed outside the event horizon. Some black holes may have nonstellar origins. Astronomers speculate that supermassive black holes at the centres of quasars and many galaxies are the source of energetic activity that is observed. Stephen W. Hawking theorized the creation of numerous tiny black holes, possibly no more massive than an asteroid, during the big bang. These primordial "mini black holes" lose mass over time and disappear as a result of Hawking radiation. Although black holes remain theoretical, the case for their existence is supported by many observations of phenomena that match their predicted effects; An object whose gravity is so strong that the escape velocity exceeds the speed of light; one possible end point of a star's life A black hole's gravity is so strong that not even light can escape it's surface; (a) Formed when a star of greater than about 10 solar masses reaches the end of its lifespan, having fused as much matter as possible The star collapses under its own gravity to a size determined by the Schwarzschild radius, at which point its gravity becomes so great that not even light can escape These objects are responsible for gravitational lensing effects and are also thought to be the explanation for some types of active galactic nuclei (b) Formed deliberately by goblins as a repository for all the socks you lose in the laundry; A region of spacetime, surrounding an extremely dense concentration of matter, in which the gravitational force is so strong that matter and energy cannot escape from it; a region in space where gravity is so strong that not even light can escape from it Black holes in our galaxy are thought to be formed when stars more than ten times as massive as our Sun end their lives in a supernova explosion There is also evidence indicating that supermassive black holes (more massive than ten billion Suns) exist in the centers of some galaxies; If the mass of a dying star is greater than about 2 to 3 solar masses then it cannot form a neutron star This is because the neutron degeneracy pressure will no longer support the star at this mass The star then completely collapses to a singularity The mass is concentrated into an infinitesimally small volume and this distorts the space-time continuum to such an extent that nothing can escape from the black hole Click here for more; a body whose escape velocity is greater than the speed of light, causing gravity to pull back toward the body any light it would otherwise emit (see black holes); A region of space around a very small and extremely massive collapsed star within which the gravitational field is so intense that not even light can escape; An object whose gravitational pull is so strong that — within a certain distance of it — nothing can escape, not even light Black holes are thought to result from the collapse of certain very massive stars at the ends of their lives, but other kinds have been postulated as well: "mini black holes,'' for example, which might have been formed in turbulance shortly after the Big Bang "Supermassive black holes'' — with masses millions of times the Sun's — may exist in the cores of large galaxies; Any object with gravity so strong that not even light can escape; A collapsed star that is so massive that its force of gravity is so strong that not even light can escape its surface; –A region of spacetime where mass has collapsed to such a degree that the escape speed from its surface exceeds the speed of light Such objects form at the end of the lives of massive stars and possibly at the beginning of the lives of galaxies; The collapsed core of a massive star Stars that are very massive will collapse under their own gravity when their fuel is exhausted The collapse continues until all matter is crushed out of existence into what is known as a singularity The gravitational pull is so strong that not even light can escape; The remains of the death and collapse of an extremely massive star The gravitational pull of a black hole is so strong that light itself cannot escape; An object whose gravity is so strong that not even light can escape from it; Superdense configuration that a body assumes when it collapses gravitationally in such a way that its powerful gravitational field prevents radiation or matter from escaping into external space; see event horizon; A dungeon or dark cell in a prison; a military lock-up or guardroom; now commonly with allusion to the cell (the Black Hole) in a fort at Calcutta, into which 146 English prisoners were thrust by the nabob Suraja Dowla on the night of June 20, 17656, and in which 123 of the prisoners died before morning from lack of air; A region of space where gravity is so strong that nothing, not even light, can escape Black holes with over a million times the sun's mass are found in quasars
Black Hole of Calcutta: a small room used as a prison in Calcutta, India. In 1756, 146 British prisoners were put into it, and most of them died in one night. People sometimes say that a small very crowded room or dark place is "like the Black Hole of Calcutta
black hole of calcutta: a dungeon (20 feet square) in a fort in Calcutta where as many as 146 English prisoners were held overnight by Siraj-ud-daula; the next morning only 23 were still alive
