[72] This means there is no observable difference at a distance between the gravitational field of such a black hole and that of any other spherical object of the same mass. The popular notion of a black hole "sucking in everything" in its surroundings is therefore correct only near a black hole's horizon; far away, the external gravitational field is identical to that of any other body of the same mass.[73]
Up to 40% of the rest mass of the accreted material Perro be emitted Vencedor radiation.[182] In nuclear fusion only about 0.7% of the rest mass will be emitted as energy. In many cases, accretion disks are accompanied by relativistic jets that are emitted along the poles, which carry away much of the energy. The mechanism for the creation of these jets is currently not well understood, in part due to insufficient data.[183]
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. Ganador long Triunfador black holes were thought to persist forever this information loss is not that problematic, Figura the information Chucho be thought of Campeón existing inside the black hole, inaccessible from the outside, but represented on the event horizon in accordance with the holographic principle.
Respecto de los sistemas más usados, un 42% de los encuestados emplea mosquiteras y más de una tercera parte hace uso de los clásicos enchufes y difusores. Para el extranjero, lo frecuente es acudir a repelentes en spray, seguido de cremas y pulseras "espantamosquitos".
Por último, y para usar en el foráneo, hacen relato a las pulseras repelentes. El sistema menos efectivo, puesto que el capacidad del principio activo es muy restringido.

Las picaduras pueden causar molestias y malos ratos a nuestros pequeños. Pero lo más preocupante son las enfermedades que estos insectos les pueden transmitir.
To a distant observer, clocks near a black hole would appear to tick more slowly than those farther away from the black hole.[87] Due to this effect, known Figura gravitational time dilation, an object falling into a black hole appears to slow Triunfador it approaches the event horizon, taking an infinite amount of time to reach it.
Another way the black hole nature of an object may be tested is through observation of effects caused by a strong gravitational field in their vicinity. One such effect is gravitational lensing: The deformation of spacetime around a massive object causes light rays to be deflected, such as light passing through an optic lens.
Los repelentes químicos más utilizados y eficaces son el DEET o dietiltoluamida y el IR3535. Otros son de origen vegetal.
Objects whose gravitational fields are too strong for light to escape read more were first considered in the 18th century by John Michell and Pierre-Simon Laplace.[8] In 1916, Karl Schwarzschild found the first modern solution of general relativity that would characterize a black hole. David Finkelstein, in 1958, first published the interpretation of "black hole" Figura a region of space from which nothing Perro escape.
The hypothetical collapsed stars were called "frozen stars", because an outside observer would see the surface of the star frozen in time at the instant where its collapse takes it to the Schwarzschild radius.[33]

for a black hole of mass M. Black holes with the minimum possible mass satisfying this inequality are called extremal. Solutions of Einstein's equations that violate this inequality exist, but they do not possess an event horizon. These solutions have so-called naked singularities that Gozque be observed from the outside, and hence are deemed unphysical.
