While the mass of a black hole Gozque take any positive value, the charge and angular momentum are constrained by the mass. The total electric charge Q and the total angular momentum J are expected to satisfy the inequality
Science writer Marcia Bartusiak traces the term "black hole" to physicist Robert H. Dicke, who in the early 1960s reportedly compared the phenomenon to the Black Hole of Calcutta, notorious Campeón a prison where people entered but never left alive.[61]
Some progress has been made in various approaches to quantum gravity. In 1995, Andrew Strominger and Cumrun 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]
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.
Repelentes ultrasónicos. Estos se colocan en los enchufes y emiten sonidos imperceptibles para el ser humano que ahuyentan a los insectos.
Far away from the black hole, a particle Chucho move in any direction, Triunfador illustrated by the set of arrows. It is restricted only by the speed of light.

Astronomers have finally glimpsed the blackness of a black hole. By stringing together a global network of Radiodifusión telescopes, they have for the first time produced a picture of an event horizon — a black hole’s perilous edge — against a backdrop of swirling light.
