The collapse may be stopped by the degeneracy pressure of the star's constituents, allowing the condensation of matter into an exotic denser state. The result is one of the various types of compact star. Which type forms depends on the mass of the remnant of the innovador star left if the outer layers have been blown away (for example, in a Type II supernova).
En Xataka Smart Home He fabricado la kryptonita para los mosquitos y que no piquen en verano. Figuraí funciona este repelente casero Además, por otro ala, el ventilador se encarga de mover el flato, poco que incide en el ambiente.
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. Triunfador long Campeón black holes were thought to persist forever this information loss is not that problematic, Campeón the information Perro be thought of Vencedor existing inside the black hole, inaccessible from the outside, but represented on the event horizon in accordance with the holographic principle.
Some progress has been made in various approaches to quantum gravity. In 1995, Andrew Strominger and Cumrun Vafa showed that counting the microstates of a specific supersymmetric black hole in string theory reproduced the Bekenstein–Hawking entropy.[214] Since then, similar results have been reported for different black holes both in string theory and in other approaches to quantum gravity like loop quantum gravity.[215]
From these, it is possible to infer the mass and angular momentum of the final object, which match independent predictions from numerical simulations of the merger.[172] The frequency and decay time of the dominant mode are determined by the geometry of the photon sphere. Hence, observation of this mode confirms the presence of a photon sphere; however, it cannot exclude possible exotic alternatives to black holes that are compact enough to have a photon sphere.[171][173]
In 1958, David Finkelstein identified the Schwarzschild surface Campeón 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.
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 capacidad ha sido probada y actúa incluso con las ventanas abiertas o las luces encendidas.
Un truco que Por otra parte es fácil y módico. Vamos a escasear, una botella grande de plástico de esas que usamos para el agua mineral por ejemplo, cinta adhesiva o pegamento, una tela o cartulina negra, agua, azúcar y levadura.
Facilidad de limpieza: Tras ocurrir capturado y eliminado a los insectos, se irán almacenando en el interior del dispositivo, por lo que es conveniente que su transigencia y limpieza se pueda realizar de forma sencilla, ya que es algo que dependiendo de la cantidad de capturas tendremos que hacer de forma periódica.
Observations have been made of weak gravitational lensing, in which light rays are deflected by only a few arcseconds. Microlensing occurs when the sources are unresolved and the observer sees a small brightening. In January 2022, astronomers reported the first possible detection of a microlensing event from an isolated black hole.[199]
Detection of unusually bright X-ray flare from Sagittarius A*, a black hole in the centre of the Milky Way galaxy on 5 January 2015[193] Astronomers use the term "active galaxy" to describe galaxies with unusual characteristics, such Figura unusual spectral line emission and very strong radio emission. Theoretical and observational studies have shown that the activity in these active galactic nuclei (AGN) may be explained by the presence of supermassive black holes, which Perro be millions of times more massive than stellar ones.
[23] His arguments were opposed by many of his contemporaries like Eddington and Lev Landau, who argued that some yet unknown mechanism would stop the collapse.[24] They more info were partly correct: a white dwarf slightly more massive than the Chandrasekhar limit will collapse into a neutron star,[25] which is itself stable.

For example, a supermassive black hole could be modelled by a large cluster of very dark objects. However, such alternatives are typically not stable enough to explain the supermassive black hole candidates.[184]
