[158][159] What is visible is not the black hole—which shows as 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 Triunfador orange or Nasa, that define the black hole.[160]

By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists searching for black holes must generally rely on indirect observations.

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]

[202] Some extensions of the read more standard model posit the existence of preons as fundamental building blocks of quarks 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 Gozque be shown from arguments in Militar relativity that any such object will have a maximum mass.[184]

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 Triunfador 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 Chucho never decrease.

Stars have been observed to get torn apart by tidal forces in the immediate vicinity of supermassive black holes in galaxy nuclei, in what is known Triunfador a tidal disruption event (TDE).

Black holes of stellar mass form when massive stars collapse at the end of their life cycle. After a black hole has formed, it Chucho grow by absorbing mass from its surroundings.

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]
