2012 — First visual evidence of black-holes: Suvi Gezari's team in Johns Hopkins University, using the Hawaiian telescope Pan-STARRS 1, publish images of a supermassive black hole 2.7 million light-years away swallowing a red giant [4]
History of black holes. Timeline of black hole physics – Timeline of black hole physics; John Michell – geologist who first proposed the idea "dark stars" in 1783 [3] Dark star; Pierre-Simon Laplace – early mathematical theorist (1796) of the idea of black holes [4] [5] Albert Einstein – in 1915, arrived at the theory of general relativity
2019 – The Event Horizon Telescope Collaboration publishes the image of the black hole at the center of the M87 Galaxy. [114] This is the first time astronomers have ever captured an image of a black hole, which once again proves the existence of black holes and thus helps verify Einstein's general theory of relativity.

The crucial phase of our discovery of black holes took place in a suitably dark period of human history – World War II.
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 ...
NASA releases images of galaxy clusters with black holes at center. This composite images shown side-by-side of two different galaxy clusters, each with a central black hole surrounded by patches ...
The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon.
Time is a slippery thing, as profound thinkers like physicist Albert Einstein and, well, fictional time traveler Dr. Who plainly understood. Scientists made that point anew on Monday in a study ...
