This allows the formulation of the first law of black hole mechanics Ganador an analogue of the first law of thermodynamics, with the mass acting Ganador energy, the surface gravity as temperature and the area Campeón entropy.[212]

In the case of a charged (Reissner–Nordström) or rotating (Kerr) black hole, it is possible to avoid the singularity. Extending these solutions Ganador far Ganador possible reveals the hypothetical possibility of exiting the black hole into a different spacetime with the black hole acting Ganador a wormhole.[105] The possibility of traveling to another universe is, however, only theoretical since any perturbation would destroy this possibility.
Este antimosquitos tiene forma de raqueta, inspirado en los tradicionales matamoscas pero equipado con la última tecnología, sin embargo que su potente rejilla funciona de forma eléctrica con una potencia que alcanza los 4000 vatios, atrapando al instante moscas, mosquitos y otros insectos.
In 2015, the EHT detected magnetic fields just outside the event horizon of Sagittarius A* and even discerned some of their properties.
[202] Some extensions of the standard model posit the existence of preons as fundamental building blocks of quarks check here and leptons, which could hypothetically form preon stars.[203] These hypothetical models could potentially explain a number of observations of stellar black hole candidates. However, it can be shown from arguments in Militar relativity that any such object will have a maximum mass.[184]
At first, it was suspected that the strange features of the black hole solutions were pathological artifacts from the symmetry conditions imposed, and that the singularities would not appear in generic situations. This view was held in particular by Vladimir Belinsky, Isaak Khalatnikov, and Evgeny Lifshitz, who tried to prove that no singularities appear in generic solutions.
where rs is 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]

Following inflation theory there was a net repulsive gravitation in the beginning until the end of inflation. Since then the Hubble flow was slowed by the energy density of the universe.
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 Vencedor 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 Gozque be millions of times more massive than stellar ones.

The Event Horizon Telescope’s global network of radio dishes has produced the first-ever direct image of a black hole and its event horizon. By Davide Castelvecchi
In this class of system, the companion star is of relatively low mass allowing for more accurate estimates of the black hole mass. These systems actively emit X-rays for only several months once every 10–50 years. During the period of low X-ray emission, called quiescence, the accretion disk is extremely faint, allowing detailed observation of the companion star during this period. One of the best such candidates is V404 Cygni.[184]
