Theoretical black hole
WebbSupermassive black holes (SMBHs) are theoretically predicted to be at the center of every galaxy and that possibly, a galaxy cannot form without one. Stephen Hawking [2] and others have proposed that these supermassive black holes spawn a supermassive white hole.

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 … Visa mer 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 … Visa mer 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 … Visa mer Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge. This result, now known as the Visa mer The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent physical … Visa mer Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether they were … Visa mer 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 … Visa mer • Binary black hole • Black brane or Black string • Black Hole Initiative • Black hole starship Visa mer Webb11 mars 2024 · A black hole is a region of the Universe where gravity is so extreme that it is impossible to escape from. The closer you get, the faster you need to travel in order to successfully run in the opposite direction. But get too close – past a boundary known as the ‘event horizon’ – and you’ll need to travel faster than the speed of light to flee.
