虫洞的分裂和膨胀

Disintegration and expansion of wormholes

I. D. Novikov, D. I. Novikov, S. V. Repin

摘要:

我们考虑类空虫洞在其平衡态被破坏后的灾难性膨胀过程。研究了随动参考系的变形动力学。我们表明,变形有一个非常具体的各向异性功能。其他作者早些时候所做的陈述,即在连接两个宇宙的虫洞膨胀过程中,这些宇宙最终合并成一个宇宙,是不正确的。我们发现,横向尺寸的虫洞(喉)的增加和走廊的长度减少,这并不对应于德西特模型。

英文摘要:

We consider the process of catastrophic expansion of a spacelike wormhole after a violation of its equilibrium state. The dynamics of deformation of the comoving reference frame is investigated. We show that the deformation has a very specific anisotropic feature. The statement made earlier by other authors, that in the process of expanding the wormhole connecting two universes these universes ultimately unite into one universe, is not correct. We show that the transverse size of the wormhole (its throat) increases and the length of the corridor decreases which does not correspond to the de Sitter model.
