This allows the formulation of the first law of black hole mechanics as an analogue of the first law of thermodynamics, with the mass acting as energy, the surface gravity as temperature and the area as entropy.[212]
The analogy was completed when Hawking, in 1974, showed that quantum field theory implies that black holes should radiate like a black body with a temperature proportional to the surface gravity of the black hole, predicting the effect now known Ganador Hawking radiation.[54]
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 as a prison where people entered but never left alive.[61]
If a black hole is very small, the radiation effects are expected to become very strong. A black hole with the mass of a car would have a diameter of about 10−24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass click here black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c2 would take less than 10−88 seconds to evaporate completely.

Estos insectos, además de ser molestos, pueden trasmitir enfermedades Vencedorí como provocar picores y rojeces en la piel. En este artículo te contamos si son efectivas o no las pulseras antimosquitos, cómo funcionan los repelentes y te damos unos consejos sobre cómo ampararse de los mosquitos.
Los repelentes químicos más utilizados y eficaces son el DEET o dietiltoluamida y el IR3535. Otros son de origen vegetal.
Since the average density of a black hole inside its Schwarzschild radius is inversely proportional to the square of its mass, supermassive black holes are much less dense than stellar black holes. The average density of a 108 M☉ black hole is comparable to that of water.[184] Consequently, the physics of matter forming a supermassive black hole is much better understood and the possible alternative explanations for supermassive black hole observations are much more mundane.
Repelentes líquidos. Estos incorporan un brinco de repelente neto que se evapora emitiendo sustancias que ahuyentan a los mosquitos.

John Michell used the term "dark star" in a November 1783 letter to Henry Cavendish[citation needed], and in the early 20th century, physicists used the term "gravitationally collapsed object".
Extrema la precaución con los niños: evita ponerles repelente en las manos para que no se las lleven a la boca y acaben ingiriéndolo accidentalmente; evita aplicar el producto directamente sobre su piel, échalo en tus manos.
At the centre of a black hole, Triunfador described by Caudillo relativity, may lie a gravitational singularity, a region where the spacetime curvature becomes infinite.[99] For a impar-rotating black hole, this region takes the shape of a single point; for a rotating black hole it is smeared pasado to form a ring singularity that lies in the plane of rotation.

The evidence for the existence of stellar and supermassive black holes implies that in order for black holes not to form, general relativity must fail Campeón a theory of gravity, perhaps due to the onset of quantum mechanical corrections. A much anticipated feature of a theory of quantum gravity is that it will not feature singularities or event horizons and thus black holes would not be Verdadero artifacts.
