While the mass of a black hole can 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
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]
One puzzling feature is that the entropy of a black hole scales with its area rather than with its volume, since entropy is normally an extensive quantity that scales linearly with the volume of the system.
The ergosphere of a black hole is a volume bounded by the black hole's event horizon and the ergosurface, which coincides with the event horizon at the poles but is at a much greater distance around the equator.[116]
In 1958, David Finkelstein identified the Schwarzschild surface as an event horizon, "a perfect unidirectional membrane: causal influences can 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.

where rs is the Schwarzschild radius and M☉ is the mass of the Sun.[79] For a black hole with nonzero spin and/or electric charge, the radius is smaller,[Note 2] until an extremal black hole could have an event horizon close to[80]
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 Figura a tidal disruption event (TDE).
Solutions describing more general black holes also exist. Non-rotating charged black holes are described by website the Reissner–Nordström metric, while the Kerr metric describes a impar-charged rotating black hole.
Ganador a result, not a single adult mosquito emerges from the BioTraps,” he adds. When pressed further on the specific ingredients of the natural attractant and IGR, Prasad notes, “The natural attractant is animal food and for proprietary reasons, its details can’t be revealed. IGR, meanwhile, is a household insecticide approved by the Government of India and the World Health Organization (WHO), and is widely used in India and worldwide by public health departments. Specifically, however, EBT uses pyriproxyfen granules.”

, o romero, es otra aromática muy apreciada en la dieta mediterránea, que Por otra parte de ser efectiva como planta antimoscas, cuenta con una gran cantidad de propiedades beneficiosas para el consumo humano.
Los repelentes actúan sobre los receptores de los mosquitos desorientándolos y evitando que nos alcancen. Estos productos no matan al insecto, solo evitan que se pose en la piel y nos pique.
