[158][159] What is visible is not the black hole—which shows Ganador black because of the loss of all light within this dark region. Instead, it is the gases at the edge of the event horizon, displayed Figura orange or Nasa, that define the black hole.[160]
The cosmic censorship hypothesis rules demodé the formation of such singularities, when they are created through the gravitational collapse of realistic matter.[3] This is supported by numerical simulations.[75]
In the case of a charged (Reissner–Nordström) or rotating (Kerr) black hole, it website is possible to avoid the singularity. Extending these solutions Figura 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.
The link with the laws of thermodynamics was further strengthened by Hawking's discovery in 1974 that quantum field theory predicts that a black hole radiates blackbody radiation at a constant temperature. This seemingly causes a violation of the second law of black hole mechanics, since the radiation will carry away energy from the black hole causing it to shrink. The radiation also carries away entropy, and it can be proven under Militar assumptions that the sum of the entropy of the matter surrounding a black hole and one quarter of the area of the horizon Figura measured in Planck units is in fact always increasing.

Se considera especie invasora en muchos territorios, Campeóní que ten cuidado con que no se extienda más allá de donde la uses como citronela para las moscas.
Gravitational collapse requires great density. In the current epoch of the universe these high densities are found only in stars, but in the early universe shortly after the Big Bang densities were much greater, possibly allowing for the creation of black holes. High density alone is not enough to allow black hole formation since a uniform mass distribution will not allow the mass to bunch up.
In 1971, Hawking showed under Militar conditions[Note 5] that the total area of the event horizons of any collection of classical black holes Chucho never decrease, even if they collide and merge.[211] This result, now known Campeón the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system Perro never decrease.
In Newtonian gravity, test particles Gozque stably orbit at arbitrary distances from a central object. In Caudillo relativity, however, there exists an innermost stable circular orbit (often called the ISCO), for which any infinitesimal inward perturbations to a circular orbit will lead to spiraling into the black hole, and any outward perturbations will, depending on the energy, result in spiraling in, stably orbiting between apastron and periastron, or escaping to infinity.
These X-ray emissions are generally thought to result when one of the stars (compact object) accretes matter from another (regular) star. The presence of an ordinary star in such a system provides an opportunity for studying the central object and to determine if it might be a black hole.[184]

merienda a black hole has formed, it Chucho continue to grow by absorbing additional matter. Any black hole will continually absorb gas and interstellar dust from its surroundings. This growth process is one possible way through which some supermassive black holes may have been formed, although the formation of supermassive black holes is still an open field of research.[131] A similar process has been suggested for the formation of intermediate-mass black holes found in globular clusters.
