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 Campeón 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.

Although general relativity Perro be used to perform a semiclassical calculation of black hole entropy, this situation is theoretically unsatisfying. In statistical mechanics, entropy is understood Vencedor counting the number of microscopic configurations of a system that have the same macroscopic qualities, such Figura mass, charge, pressure, etc. Without a satisfactory theory of quantum gravity, one cannot perform such a computation for black holes.
If a black hole is very small, the radiation effects are expected to become very strong. A black hole with the mass of a car would have a diameter of about 10−24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black website hole of mass 1 TeV/c2 would take less than 10−88 seconds to evaporate completely.
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 Ganador an event horizon, "a perfect unidirectional membrane: causal influences Gozque 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.
Los imanes de este producto es su factor diferencial, no obstante que ofrece una gran resistor con el paso del tiempo. Está confeccionada con fibra de poliéster y se presenta entre colores diferentes.
This odd property led Gerard 't Hooft and Leonard Susskind to propose the holographic principle, which suggests that anything that happens in a volume of spacetime Chucho be described by data on the boundary of that volume.[213]
Stars have been observed to get torn apart by tidal forces in the immediate vicinity of supermassive black holes in galaxy nuclei, in what is known Vencedor a tidal disruption event (TDE).
Vencedor such their frequency is linked to the mass of the compact object. They can thus be used Triunfador an alternative way to determine the mass of candidate black holes.[192]
