Black holeBack-reactionWe construct a one-loop effective metric describing the evaporation phase of a Schwarzschild black hole in a spherically symmetric null-dust model. This is achieved by quantising the Vaidya solution and by chosing a time dependent quantum state. This state describes a black...
The second case is that of a Schwarzschild black hole. The full manifold is described in the (T,X) coordinates, (called the Kruskal coordinates, which are analogous to the inertial coordinates in flat spacetime) but the metric is not static in terms of the Kruskal time T. The horizon at...
(Schwarzschild metric),又称 史瓦西解 ,是卡尔·史瓦西于1915年针对广义相对论的核心方程式—— 爱因斯坦场方程 式——关于球状物质分布的解。根据 伯考夫定理 (Birkhoff's theorem),史瓦西解可说是爱因斯坦方程式最一般的球对称真空解。这样的解又被称作史瓦西黑洞,此种几何对应一个静止不旋转、不带电荷之黑洞。
By allowing the lightcones to tip over according to the conservation laws of an one-kink in static, Schwarzschild metric, we show that there also exists an instanton which represents production of pairs of chargeless, nonrotating black holes with mass $M$, joined on an interior surface ...
Based in these experiments a modified Schwarzschild metric was obtained in order to calculate a quantum corrections in Schwarzschild black hole thermodynamics and tunneling probability. It was found that GUP placed restrictions on the minimum mass, size and temperature of the black hole, indicating ...
Also, Kiselev rewrote the Schwarzschild metric by taking into account the quintessence field in the background. In this study, we consider the quantum-corrected Schwarzschild black hole inspired by Kazakov-Solodukhin's work, and Schwarzschild black hole surrounded by quintessence deduced by Kiselev ...
Thus, we have seen that in the vicinity of the central black hole mass, a second time dimension keeps the metric bounded rather than diverging to infinity. Thus, we have found a solution to the singularity problem of black holes. This work serves as a steppingstone for further investigations...
Learn about the Schwarzschild radius as it pertains to black holes. Topics include the event horizon of a black hole and how Einstein used the Schwarzschild metric. Updated: 11/21/2023 Table of Contents Schwarzschild Black Hole What Is the Schwarzschild Radius? Black Hole Classification Lesson ...
Schwarzschild coordinates (r,t) fail to describe the region within the event horizon (EH), (r <= 2 M), of a Black Hole (BH) because the metric coefficients exhibit singularity at r=2 M, and the radial geodesic of a particle appears to be null (ds^2 =0) when actually it must be...
The metric of a Schwarzschild black hole with a gravitational perturbation [65,66,67] can be expressed as ds2=(gμν+ϵhμν)dxμdxν, (1) which is a particular solution of Einstein equations expanded up to the first order inϵ. The metricgμνin Eq. (1) is the metric tensor ...
