Schwarzschild-de Sitter世界中的真空壳

Vacuum shell in the Schwarzschild-de Sitter world

S. V. Chernov, V. I. Dokuchaev

摘要:

我们构造的分类方案,所有可能的演化方案,并找到相应的全球几何薄球形真空壳动力学的Schwarzschild-de Sitter度量。这种结构适合于模拟早期宇宙中宇宙学相变过程中产生的真空泡。从一个相当遥远的观察者的局部观点来看,演化的独特的最终类型要么是壳层的无限膨胀,要么是壳层的收缩,形成黑洞(有一个中心奇点)或虫洞(内部有一个婴儿宇宙)。

英文摘要:

We construct the classification scheme for all possible evolution scenarios and find the corresponding global geometries for dynamics of a thin spherical vacuum shell in the Schwarzschild-de Sitter metric. This configuration is suitable for the modelling of vacuum bubbles arising during cosmological phase transitions in the early Universe. The distinctive final types of evolution from the local point of view of a rather distant observer are either the unlimited expansion of the shell or its contraction with a formation of black hole (with a central singularity) or wormhole (with a baby universe in interior).
