1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
Intermediate-mass black hole – black hole whose mass is significantly more than stellar black holes yet far less than supermassive black holes. Supermassive black hole – largest type of black hole in a galaxy, on the order of hundreds of thousands to billions of solar masses. Quasar – very energetic and distant active galactic nucleus.
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.

Scientists have discovered the oldest black hole yet, a cosmic beast formed a mere 470 million years after the Big Bang. The findings, published Monday, confirm what until now were theories that ...
Astronomers detected the black hole in a galaxy called UHZ1. At first glance, the galaxy appeared in the same direction as a cluster of galaxies known as Abell 2744, which is located about 3.5 ...
2016 – Topological order – topological phase transitions and order – recognized (Nobel prize, David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz) 2019 – First image of a black hole; 2023 – Experimental evidence of stochastic Gravitational wave background [14]
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 Black Hole Era is defined as "40 < n < 100". In this era, according to the book, organized matter will remain only in the form of black holes. Black holes themselves slowly "evaporate" away the matter contained in them, by the quantum mechanical process of Hawking radiation. By the end of this era, only extremely low-energy photons ...
