The centers of galaxy clusters contain the universe’s most massive galaxies, which, in turn, contains gigantic black holes ranging in mass from millions to tens of billions of times that of the ...
The term "black hole" was used in print by Life and Science News magazines in 1963, and by science journalist Ann Ewing in her article " 'Black Holes' in Space", dated 18 January 1964, which was a report on a meeting of the American Association for the Advancement of Science held in Cleveland, Ohio.

In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
The observations stretch back to about 12.3 billion years ago, when the universe was roughly a tenth Ferocious black holes reveal 'time dilation' in early universe Skip to main content
A major constraining factor for theories of supermassive black hole formation is the observation of distant luminous quasars, which indicate that supermassive black holes of billions of M ☉ had already formed when the Universe was less than one billion years old. This suggests that supermassive black holes arose very early in the Universe ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
Supermassive black holes sometimes shoot vast jets of high-energy particles into space, but no such jet has been detected in this instance, according to astrophysicist and study co-author Lorena ...
A black hole cosmology (also called Schwarzschild cosmology or black hole cosmological model) is a cosmological model in which the observable universe is the interior of a black hole. Such models were originally proposed by theoretical physicist Raj Kumar Pathria, [1] and concurrently by mathematician I. J. Good. [2]
