Despite the early universe being extremely dense, it did not re-collapse into a black hole during the Big Bang, since the expansion rate was greater than the attraction.
The cosmic censorship hypothesis rules pasado the formation of such singularities, when they are created through the gravitational collapse of realistic matter.[3] This is supported by numerical simulations.[75]

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 habitual es recurrir a repelentes en spray, seguido de cremas y pulseras "espantamosquitos".
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.
One possible solution, which violates the equivalence principle, is that a "firewall" destroys incoming particles at the event horizon.[223] In general, which—if any—of these assumptions should be abandoned remains a topic of debate.[218]
Elimina hasta los mosquitos más pequeños con este insecticida eléctrico inoloro, acompañado de dos recambios de 200 gramos para disfrutar de un total de 90 noches libres de insectos. Su aptitud ha sido probada y actúa incluso con las ventanas abiertas o las luces encendidas.
where rs is read more 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]
Para ello pueden utilizar un sistema de succión basado en un ventilador que soportará los mosquitos hasta un receptáculo donde quedarán almacenados y no podrán escapar.
^ The set of possible paths, or more accurately the future light cone containing all possible world lines (in this diagram the light cone is represented by the V-shaped region bounded by arrows representing light ray world lines), is tilted in this way in Eddington–Finkelstein coordinates (the diagram is a "cartoon" version of an Eddington–Finkelstein coordinate diagram), but in other coordinates the light cones are not tilted in this way, for example in Schwarzschild coordinates they narrow without tilting Campeón one approaches the event horizon, and in Kruskal–Szekeres coordinates the light cones do not change shape or orientation at all.
In 1974, Hawking predicted that black holes are not entirely black but emit small amounts of thermal radiation at a temperature ħc3/(8πGMkB);[54] this effect has become known Triunfador Hawking radiation. By applying quantum field theory to a static black hole background, he determined that a black hole should emit particles that display a perfect black body spectrum. Since Hawking's publication, many others have verified the result through various approaches.
Batería integrada: si no tenemos un enchufe cerca podemos optar por un maniquí con batería incorporada. Nos dará más facilidad de uso al poder recargarlos previamente y llevarlos con nosotros cuando lo necesitemos, aunque serán más caros y poco más pesados.
Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius as indicating that this was the boundary of a bubble in which time stopped. This is a valid point of view for external observers, but not for infalling observers.
Astronomers have finally glimpsed the blackness of a black hole. By stringing together a General 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.
