Furthermore we should point that the nonsingular charged black holes obtained from NEM models in curved space-time cause the photons to not move along null geodesics. Recently, however, Mbonye and Kazanas have found an exact solution to Einsteins equations which contains no central singularity.1 Mbonye and Kazanas arrived at their solution by assuming a black hole contains exotic matter. Today some of the most viable candidates for the end result of the collapse of a star with mass well above the Chandrasekhar limit include the gravastar and the dark energy star. Later the same authors reinterpreted the first non-singular black hole geometry, the Bardeen toy Model,[9] as a nonlinear-electrodynamics-based regular black hole.

To the five then plus uh twice X cubed. (: Sonic Black Hole) Dumb Hole . We describe a possible generalization of a nonsingular black-hole metric to the case when this equality is violated. Nonsingular black hole models have been proposed since theoretical problems with black holes were first realized. In other words, an infalling object causes the horizon of a black hole to expand, which only occurs after the object has fallen into the hole, allowing an observable horizon in finite time. This requires an accurate theory of black hole formation, of which several have been proposed. Paula, Marco; Leite, Luiz; Crispino, Lus (12 November 2020). A quasar (/ k w e z r / KWAY-zar; also know Another approach to the problem is to find a mechanism by which the singularity never forms in the first place. Bardeen, JM (1968). One way to get around singularities is by simply ignoring them.

Exotic matter is a theoretical material which has a negative energy density instead of the usual positive energy density. Unlike CGHS, the modified models are non-singular and For a black hole to physically exist as a solution to Einstein's equation, it must form an event horizon in finite time relative to outside observers. For example, several alternative black hole models were shown to be unstable in extremely fast rotation,[6] which, by conservation of angular momentum, would be a not unusual physical scenario for a collapsed star (see pulsar). [citation needed] Today some of the most viable candidates for the result of the collapse of a star with mass well above the Chandrasekhar limit include the gravastar and the dark energy star. Roger Penrose even went so far as to propose the cosmic censorship hypothesis, which argues that every singularity must be enclosed by an event horizon, which hides it from the universe. "Formation and evaporation of non-singular black holes". This page was last edited on 24 October 2022, at 02:16. Unlike CGHS, the modied models are non-singular and geodesically complete.

This negative energy density means that exotic matter can hold its own against gravity. ; ESA An artist concept of a black hole. We dont know what dark energy is, but we do know two things: it cannot be regular matter, and it has a negative energy density. For a black hole to physically exist as a solution to Einstein's equation, it must form an event horizon in finite time relative to outside observers. This means gravity cant win no matter how hard it tries, and it is impossible to form a singularity. (26 January 2006). Contents. It is this feedback loop which means that gravity wins in the end. In other words, an infalling object causes the horizon of a black hole to expand, which only occurs after the object has fallen into the hole, allowing an observable horizon in finite time.
