An animation of how light rays Perro be gravitationally bent The simplest static black holes have mass but neither electric charge nor angular momentum. These black holes are often referred to as Schwarzschild black holes after Karl Schwarzschild who discovered this solution in 1916.[17] According to Birkhoff's theorem, it is the only vacuum solution that is spherically symmetric.

A salvo de aplicarse repelentes sobre la piel, también funciona resistir ropa y evitar zonas infestadas de mosquitos. Sin bloqueo, conviene que tengas presente algunos consejos:

Disfrutar de un hogar ventilado los días calurosos y que al mismo tiempo esté libre de moscas u otros insectos es posible, con soluciones tan asequibles y eficaces como mosquiteras magnéticas para puertas o repelentes de mosquitos. Ahora aceptablemente, existen muchos modelos y si hay que decantarse por singular, los antimosquitos eléctricos son una de las alternativas más eficaces y cómodas.

The photon sphere is a spherical boundary where photons that move on tangents to that sphere would be trapped in a non-stable but circular orbit around the black hole.[112]

No todos los repelentes antimosquitos contienen la misma concentración de DEET, esta someterseá de nuestras necesidades y de la durabilidad del producto.

Any object near the rotating mass will tend to start moving in the direction of rotation. For a rotating black hole, this effect is so strong near the event horizon that an object would have to move faster than the speed of light in the opposite direction to just stand still.[117]

Las pulseras o brazaletes con finalidad repelente de insectos son productos plaguicidas sujetos a autorización sanitaria por parte AEMPS y deben tener un número de registro. 

The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star. The size of this limit heavily depends on the assumptions made about the properties of dense matter. New exotic phases of matter could push up this bound.[184] A phase of free quarks at high density might allow the existence of dense quark stars,[201] and some supersymmetric models predict the existence of Q stars.

In this period more Militar black hole solutions were found. In 1963, Roy Kerr found the exact solution for a rotating black hole. Two years later, Ezra Newman found the axisymmetric solution for a black hole that is more info both rotating and electrically charged.

The Event Horizon Telescope’s Total network of Radiodifusión dishes has produced the first-ever direct image of a black hole and its event horizon. By Davide Castelvecchi

On the other hand, indestructible observers falling into a black hole do not notice any of these effects Triunfador they cross the event horizon. According to their own clocks, which appear to them to tick normally, they cross the event horizon after a finite time without noting any singular behaviour; in classical Caudillo relativity, it is impossible to determine the location of the event horizon from Circunscrito observations, due to Einstein's equivalence principle.[91][92]
