Zhang, Shuang Nan; Liu, Yuan (2008). A nonsingular black hole model is a mathematical theory of black holes that avoids certain theoretical problems with the standard black hole model, including information loss and the unobservable nature of the black hole event horizon. 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. The metric was written down by Sean Hayward as the minimal model that is regular, static, spherically symmetric and asymptotically flat. We employ a probability distribution inspired mass function m ( r) to replace the Kerr black hole mass M to represent a nonsingular rotating black hole that is identified asymptotically ( r \gg k, k>0 constant) exactly as the Kerr-Newman black hole, and as the Kerr black hole when k=0. [10] Nowadays, it is known that the Ayn-BeatoGarca model may mimic the absorption properties of the ReissnerNordstrm metric, from the perspective of the absorption of massless test scalar fields. As a result all the matter within a black hole is squeezed down to a point of zero volume and infinite density, known as a singularity. 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. Nonsingular black hole models have been proposed since theoretical problems with black holes were first realized. In addition, the nonsingular black hole (14) is a novel class of regular black hole, unlike the Bardeen and Hayward regular black holes, has an asymptotically Minkowski core [45]. Matter and energy can fall into a black hole, but anything that crosses the event horizon is forever stuck inside. 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).

We describe a possible generalization of a nonsingular black-hole metric to the case when this equality is violated. In 2007, Shuan Nan Zhang of Tsinghua University proposed a model in which the event horizon of a potential black hole only forms (or expands) after an object falls into the existing horizon, or after the horizon has exceeded the critical density. green card spillover 2023 predictions trackitt. Function: view, File: /home/ah0ejbmyowku/public_html/index.php Zhang, Shuang Nan; Tang, Sumin (2007-07-06). The Hayward metric is the simplest description of a black hole that is non-singular. By mathematically sewing the two solutions together, one gets a non-singular black hole. "Electrically charged black holes in linear and nonlinear electrodynamics: Geodesic analysis and scalar absorption". While black holes were a well-established part of mainstream physics for most of the end of the 20th century, alternative models received new attention when models proposed by George Chapline and later by Lawrence Krauss, Dejan Stojkovic, and Tanmay Vachaspati of Case Western Reserve University showed in several separate models that black hole horizons could not form.[3][4].

It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [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. When gravity squeezes on exotic matter, its energy density goes down. This requires an accurate theory of black hole formation, of which several have been proposed. Find if this function has an inverse, right? A nonsingular black hole model is a mathematical theory of black holes that avoids certain theoretical problems with the standard black hole model, including information loss and the unobservable nature of the black hole event horizon. Most of the effort in this area has been to find patchwork solutions to Einsteins equations for general relativity. The recent theoretical results have therefore undergone much scrutiny and most of them are now ruled out by theoretical studies. Nonsingular black hole models have been proposed since theoretical problems with black holes were first realized. Mbonye and Kazanas dont specify what this exotic matter is, but their formulation implies one possible candidate: dark energy. 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. The root cause of all black holesbe they tiny primordial black holes, solar mass black holes, or supermassive galactic black holesis gravity. Nonsingular black hole models and Outline of astronomy Collapse Mathematical theory of black holes that avoids certain theoretical problems with the standard black hole model, including information loss and the unobservable nature of the black hole event horizon. Since the singularity always resides within the event horizon, we can never observe it from the outside. The recent theoretical results have therefore undergone much scrutiny and most of them are now ruled out by theoretical studies. A nonsingular black hole model is a mathematical theory of black holes that avoids certain theoretical problems with the standard black hole model, including information loss and the unobservable nature of the black hole event horizon. There is an explanation why the Krauss model is wrong.The simply reason why these models are not ruled out by other is that one does't take them serious except some persons who have no idea of GR, too. This means gravity cant win no matter how hard it tries, and it is impossible to form a singularity. ity.

[7], The Ayn-BeatoGarca model is the first exact charged regular black hole with a source. One way to get around singularities is by simply ignoring them. The depicted spacetime which is type [II, (II)], by Petrov classification, is an exact solution of the Einstein equations and contains two horizons. We also obtain a metric for a charged nonsingular black hole obeying similar restrictions as the neutral one and construct higher dimensional models of neutral and charged black holes. Such research has attracted much media attention,[5] as black holes have long captured the imagination of both scientists and the public for both their innate simplicity and mysteriousness. Black hole formation in a contracting universe . This page was last edited on 24 October 2022, at 02:16. So you have 1/27 uh multiplied by this X. But this hypothesis has never been proven in general, and several theoretical counter-examples (known as naked singularities) have been found. The metric was written down by Sean Hayward as the minimal model that is regular, static, spherically symmetric and asymptotically flat. In this paper, we study shadow of this nonsingular black hole using three kinds of observers, i.e. Communication . CGHS model has 2D black hole solutions that are remark- quadrature integrals can be calculated in closed form! Hayward, Sean A. One of the successful regular models of black holes (BHs), avoiding singularities, was proposed by Hayward [ 1 ]. Mbonye and Kazanas havent proven that their exotic matter is dark energy, but their work points to the idea that maybe, just maybe, one of newest mysteries of gravitational astrophysics might just solve one of the oldest ones.

To the five then plus uh twice X cubed. But singularities can be considered to be nonphysical due to classical GR, and it is natural to think that singularities should be avoided. [11], Avoiding paradoxes in the standard black hole model. 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.

The Hayward metric is the simplest description of a black hole that is non-singular. 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. The Hayward metric function contains a length parameter l to smooth the singularity. New model of axion monodromy inflation and its cosmological implications Journal of Cosmology and Astroparticle Physics June 10, 2016 See publication. Regular black hole models with direct matching of the de Sitter interior and the Schwarzschild exterior have been proposed by Poisson and Israel [12], Frolov et al.

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. The harder gravity squeezes, the harder it can squeeze, until all that remains is the singularity. As we shall see, the maximal curva-ture is proportional to 1/LPlanck. Such research has attracted much media attention,[5] as black holes have long captured the imagination of both scientists and the public for both their innate simplicity and mysteriousness. We propose a novel nonsingular black-hole spacetime representing a strong deformation of the Schwarzschild solution with mass by an additional hair , which may be hierarchically larger than the Planck scale. we investigated if nonsingular bouncing models satisfy the generalized second law of thermodynamics.
