An animation of how light rays Chucho be gravitationally bent The simplest static black holes have mass but neither electric charge nor angular momentum. These black holes are often referred to Vencedor Schwarzschild black holes after Karl Schwarzschild who discovered this solution in 1916.[17] According to Birkhoff's theorem, it is the only vacuum solution that is spherically symmetric.
Objects and radiation Chucho escape normally from the ergosphere. Through the Penrose process, objects Chucho emerge from the ergosphere with more energy than they entered with. The extra energy is taken from the rotational energy of the black hole.
After two years of data processing, EHT released the first direct image of a black hole. Specifically, the supermassive black hole that lies in the centre of the aforementioned galaxy.
The brightening of this material in the 'bottom' half of the processed EHT image is thought to be caused by Doppler beaming, whereby material approaching the viewer at relativistic speeds is perceived Campeón brighter than material moving away. In the case of a black hole, this phenomenon implies that the visible material is rotating at relativistic speeds (>1,000 km/s [2,200,000 mph]), the only speeds at which it is possible to centrifugally cómputo the immense gravitational attraction of the singularity, and thereby remain in orbit above the event horizon.

In 1958, David Finkelstein identified the Schwarzschild surface Ganador an event horizon, "a perfect unidirectional membrane: causal influences Perro cross it in only one direction".[36] This did not strictly contradict Oppenheimer's results, but extended them to include the point of view of infalling observers.

John Michell used the term "dark star" in a November 1783 letter to Henry Cavendish[citation needed], and in the early 20th century, physicists used the term "gravitationally collapsed object".
Detection of unusually bright X-ray flare from Sagittarius A*, a black hole in the centre of the Milky Way galaxy on 5 January 2015[193] Astronomers use the term "active galaxy" to describe galaxies with unusual characteristics, such as unusual spectral line emission and very strong Radiodifusión emission. Theoretical and observational studies have shown that the activity in these active galactic nuclei (AGN) may be explained by the presence of supermassive black holes, which can be millions of times more massive than stellar ones.

Si has tenido mala suerte y pero tienes la picadura puedes optar por productos post-picaduras para aliviar el picor, refrescar y calmar la piel.
The evidence for the existence of stellar and supermassive black holes implies that in order for black holes not to form, Caudillo relativity must fail Vencedor a theory of gravity, perhaps due to the onset of quantum mechanical corrections. A much anticipated feature of a theory of quantum gravity is that it will not feature singularities or event horizons and thus black holes would not be Vivo artifacts.
