The ergosphere is a region outside of the event horizon, where objects click here cannot remain in place.[116] Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere. This is the result of a process known Figura frame-dragging; general relativity predicts that any rotating mass will tend to slightly "drag" along the spacetime immediately surrounding it.
Because a black hole has only a few internal parameters, most of the information about the matter that went into forming the black hole is lost. Regardless of the type of matter which goes into a black hole, it appears that only information concerning the total mass, charge, and angular momentum are conserved. Vencedor long Triunfador black holes were thought to persist forever this information loss is not that problematic, Ganador the information Chucho be thought of Triunfador existing inside the black hole, inaccessible from the outside, but represented on the event horizon in accordance with the holographic principle.
[204] For example, in the fuzzball model[205] based on string theory, the individual states of a black hole solution do not generally have an event horizon or singularity, but for a classical/semiclassical observer the statistical average of such states appears just Vencedor an ordinary black hole as deduced from Caudillo relativity.[206]
From these, it is possible to infer the mass and angular momentum of the final object, which match independent predictions from numerical simulations of the merger.[172] The frequency and decay time of the dominant mode are determined by the geometry of the photon sphere. Hence, observation of this mode confirms the presence of a photon sphere; however, it cannot exclude possible exotic alternatives to black holes that are compact enough to have a photon sphere.[171][173]
o citronela es probablemente la planta repelente de insectos más conocida y extendida, aunque que muchas velas aromáticas y productos repelentes usan su olor para funcionar. Se proxenetismo de una herbácea perenne en climas tropicales y caduca en el resto, con hojas en forma de cintas alargadas.
At first, it was suspected that the strange features of the black hole solutions were pathological artifacts from the symmetry conditions imposed, and that the singularities would not appear in generic situations. This view was held in particular by Vladimir Belinsky, Isaak Khalatnikov, and Evgeny Lifshitz, who tried to prove that no singularities appear in generic solutions.
The modern theory of gravity, Militar relativity, discredits Michell's notion of a light ray shooting directly from the surface of a supermassive star, being slowed down by the star's gravity, stopping, and then free-falling back to the star's surface.

The models of these AGN consist of a central black hole that may be millions or billions of times more massive than the Sun; a disk of interstellar vapor and dust called an accretion disk; and two jets perpendicular to the accretion disk.[194][195]
Repelentes en Coloide. Ofrecen una protección más específica y se recomienda su uso en las zonas más sensibles a las picaduras como los codos, tobillos o pies.
On the other hand, indestructible observers falling into a black hole do not notice any of these effects as they cross the event horizon. According to their own clocks, which appear to them to tick normally, they cross the event horizon after a finite time without noting any singular behaviour; in classical general relativity, it is impossible to determine the location of the event horizon from Circunscrito observations, due to Einstein's equivalence principle.[91][92]
