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.

The analogy was completed when Hawking, in 1974, showed that quantum field theory implies that black holes should radiate like a black body with a temperature proportional to the surface gravity of the black hole, predicting the effect now known Vencedor Hawking radiation.[54]

For stars this usually occurs either because a star has too little "fuel" left to maintain its temperature through stellar nucleosynthesis, or because a star that would have been stable receives extra matter in a way that does not raise its core temperature. In either case the star's temperature is no longer high enough to prevent it from collapsing under its own weight.[130]

The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity, and it has been argued that loss of unitarity would also imply violation of conservation of energy,[217] though this has also been disputed.

In 1958, David Finkelstein identified the Schwarzschild surface as 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.

Light from the collapsing material takes longer and longer to reach the observer, with the light emitted just before the event horizon forms delayed an infinite amount of time. Thus the external observer never sees the formation of the event horizon; instead, the collapsing material seems to become dimmer and increasingly red-shifted, eventually fading away.[133]

The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star. The size of this limit heavily depends on the assumptions made about the properties of dense matter. New exotic phases of matter could push up this bound.[184] A phase of free quarks at high density might allow the existence of dense quark stars,[201] and some supersymmetric models predict the existence of Q stars.

Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius Figura indicating that this was the boundary of a bubble in which time stopped. This is a valid point of view for external observers, but not for infalling observers.

"[11] If other stars are orbiting a black hole, their orbits Gozque be used to determine the black hole's mass and location. Such observations can be used to exclude possible alternatives such Vencedor neutron stars. In this way, astronomers have identified numerous stellar black hole candidates in binary systems and established that the Radiodifusión source known as Sagittarius A*, at the core of the Milky Way galaxy, contains a supermassive black click here hole of about 4.3 million solar masses.
