WebA black hole is made when the centre of a very big star falls in upon itself, or collapses. All the matter of the star becomes squeezed into a tiny space and the force of gravity … 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 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 … 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 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
