Black hole Definition, Formation, Types, Pictures, & Facts
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 no … 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 By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists … 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 … See more • Binary black hole • Black brane or Black string • Black Hole Initiative • Black hole starship • Black holes in fiction 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 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 Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any … See more WebMay 17, 2012 · The result of this recoil matches observations of the universe's shape, geometry, and distribution of mass. In turn, the torsion mechanism suggests an astonishing scenario: every black hole would … Before Stephen Hawking came up with the concept of Hawking radiation, the question of black holes having entropy had been avoided. However, this concept demonstrates that black holes radiate energy, which conserves entropy and solves the incompatibility problems with the second law of thermodynamics. Entropy, however, implies heat and therefore temperature. The loss of energy also implies that black holes do not last forever, but rather evaporate or decay slowly.
