[106] It also appears to be possible to follow closed timelike curves (returning to one's own past) around the Kerr singularity, which leads to problems with causality like the grandfather paradox.[107] It is expected that none of these peculiar effects would survive in a proper quantum treatment of rotating and charged black holes.[108]
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. Campeón long Triunfador black holes were thought to persist forever this information loss is not that problematic, Vencedor the information Chucho be thought of as existing inside the black hole, inaccessible from the outside, but represented on the event horizon in accordance with the holographic principle.

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]
Nevertheless, these observations strongly suggest that the central object is a supermassive black hole Figura there are no other plausible scenarios for confining so much invisible mass into such a small volume.[177] Additionally, there is some observational evidence that this object might possess an event horizon, a feature unique to black holes.[178]

The modern theory of gravity, Caudillo 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.
Models for the gravitational collapse of objects of relatively constant size, such as stars, do not necessarily apply in the same way to rapidly expanding space such Figura the Big Bang.[134]
Observations have been made of weak gravitational lensing, in which light rays are deflected by only a few arcseconds. Microlensing occurs when the sources are unresolved and the observer sees a small brightening. In January 2022, astronomers reported the first possible detection of a microlensing event from an isolated black hole.[199]

.. when a star is Campeón small Vencedor the critical circumference, the curvature is strong but not infinite, and space is definitely not wrapped around the star. Eddington may have known this, but his description made a good story, and it captured in a whimsical way the spirit of Schwarzschild's spacetime curvature." ^

[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 Perro be prograde (the photon rotates in the same sense of the black hole spin) or retrograde.[114][115]
