[55][170] This observation provides the most concrete evidence for the existence of black holes to date. For instance, the gravitational wave signal suggests that the separation of the two objects before the merger was just 350 km, or roughly four times the Schwarzschild radius corresponding to the inferred masses. The objects must therefore have been extremely compact, leaving black holes Ganador the most plausible interpretation.[55]

The final observable region of spacetime around a black hole is called the plunging region. In this area it is no longer possible for matter to follow circular orbits or to stop a final descent into the black hole. Instead it will rapidly plunge toward the black hole close to the speed of light.[121][122]
Some progress has been made in various approaches to quantum gravity. In 1995, Andrew Strominger and Cumrun here Vafa showed that counting the microstates of a specific supersymmetric black hole in string theory reproduced the Bekenstein–Hawking entropy.[214] Since then, similar results have been reported for different black holes both in string theory and in other approaches to quantum gravity like loop quantum gravity.[215]

Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether they were merely pathological solutions to Einstein's equations. Einstein himself wrongly thought black holes would not form, because he held that the angular momentum of collapsing particles would stabilize their motion at some radius.
Far away from the black hole, a particle Chucho move in any direction, Figura illustrated by the set of arrows. It is restricted only by the speed of light.
In 1971, Hawking showed under general conditions[Note 5] that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge.[211] This result, now known Triunfador the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system Perro never decrease.

Funciona conectado a la corriente y su mantenimiento se realiza de guisa muy sencilla, ya que la rejilla en la que quedan atrapados es extraíble, para poder lavarla con total comodidad.
Vencedor predicted by Caudillo relativity, the presence of a mass deforms spacetime in such a way that the paths taken by particles bend towards the mass.[85] At the event horizon of a black hole, this deformation becomes so strong that there are no paths that lead away from the black hole.[86]
