可穿越虫洞的新解析模型

New analytic models of traversable wormholes

Alexander Shatskiy, I. D. Novikov, N. S. Kardashev

摘要:

给出了球对称虫洞的广义相对论方程的解析解。我们研究的特殊情况下,一个“可穿越”虫洞,即,虫洞物质的能量-动量张量被表示为球对称磁场和具有负物质密度的尘埃物质的叠加。研究了该模型的动力学性质。我们讨论了有无λ项的方程的解,通过叠加足够多的尘埃物质、磁场和λ项,可以得到一个静态解,它是一个由无穷多个虫洞连接的球形宇宙的球形多元宇宙模型。相应的解决方案可以是静态的和动态的。

英文摘要:

The analytic solution of the general relativity equations for spherically symmetric wormholes are given. We investigate the special case of a "traversable" wormhole i.e., one allowing the signal to pass through it. The energy-momentum tensor of wormhole matter is represented as a superposition of a spherically symmetric magnetic field and dust matter with negative matter density. The dynamics of the model are investigated. We discuss both the solution of the equation with a Lambda-term and without it. Superposing enough dust matter, a magnetic field, and a Lambda-term can produce a static solution, which turns out to be a spherical Multiverse model with an infinite number of wormholes connected spherical universes. Corresponding solution can be static and dynamic.
