A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy (e.g. light) can escape it. [2] Albert Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. [3] [4] The boundary of no escape is called the event horizon.
The first image (silhouette or shadow) of a black hole, taken of the supermassive black hole in M87 with the Event Horizon Telescope, released in April 2019. The black hole information paradox [1] is a paradox that appears when the predictions of quantum mechanics and general relativity are combined.
Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
The famous first picture of the supermassive black hole at the heart of our galaxy might not be accurate, a new study has claimed. The picture – initially published in 2022, after years of ...
It also confirms that the black hole is truly huge, with a mass 6.5 billion times that of the Sun. As you might imagine, taking this picture was tricky -- it required worldwide collaboration that ...
Scientists have revealed the first ever image taken of a black hole. While the black hole itself is invisibly dark, astronomers managed to observe the “point-of-no-return” precipice around its ...
The Black Hole is a 1979 American science fiction film directed by Gary Nelson and produced by Walt Disney Productions.The film stars Maximilian Schell, Robert Forster, Joseph Bottoms, Yvette Mimieux, Anthony Perkins and Ernest Borgnine, while the voices of the main robot characters are provided by Roddy McDowall and Slim Pickens (both uncredited).
Scientists have revealed an astonishing new image of the black hole in the middle of our galaxy. The object – known as Sagittarius A* – is shown in polarised light for the first time, in a ...
