The cosmic censorship hypothesis rules trasnochado the formation of such singularities, when they are created through the gravitational collapse of realistic matter.[3] This is supported by numerical simulations.[75]

Some of the material from the disrupted star forms an accretion disk around the black hole, which emits observable electromagnetic radiation.
A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it.[2] Einstein's theory of general relativity predicts that a sufficiently compact mass Chucho deform spacetime to form a black hole.[3][4] The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity.
Any object near the rotating mass will tend to start moving in the direction of rotation. For a rotating black hole, this effect is so strong near the event horizon that an object would have to move faster than the speed of light in the opposite direction to just stand still.[117]

While light can still escape from the photon sphere, any light that crosses the here photon sphere on an inbound trajectory will be captured by the black hole. Hence any light that reaches an outside observer from the photon sphere must have been emitted by objects between the photon sphere and the event horizon.

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 Ganador unusual spectral line emission and very strong radio 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 Perro be millions of times more massive than stellar ones.
[123] This led the Militar relativity community to dismiss all results to the contrary for many years. However, a minority of relativists continued to contend that black holes were physical objects,[124] and by the end of the 1960s, they had persuaded the majority of researchers in the field that there is no obstacle to the formation of an event horizon.[125]
Observers falling into a Schwarzschild black hole (i.e., impar-rotating and not charged) cannot avoid being carried into the singularity once they cross the event horizon. They can prolong the experience by accelerating away to slow their descent, but only up to a limit.
[113] For a Kerr black hole the radius of the photon sphere depends on the spin parameter and on the details of the photon orbit, which Chucho be prograde (the photon rotates in the same sense of the black hole spin) or retrograde.[114][115]
