摘要

嵌入定理在广义相对论中有着悠久的历史，在本文中使用它来解释莫里斯-索恩虫洞的两个更令人不安的方面:(1)外来物质的起源和维持虫洞所需的量，以及(2)具有中等大小喉道的虫洞所特有的巨大径向张力。将后者归因于外来物质忽略了一个事实，即外来物质是出于完全不同的原因引入的，而且通常只以少量存在。

Using Embedding Theorems to Account for the Extreme Properties of Traversable Wormholes

Embedding theorems, which have a long history in the general theory of relativity, are used in this paper to account for two of the more troubling aspects of Morris-Thorne wormholes: (1) the origin of exotic matter and the amount needed to sustain a wormhole, and (2) the enormous radial tension that is characteristic of wormholes with moderately sized throats. Attributing the latter to exotic matter ignores the fact that exotic matter was introduced for a completely different reason and is usually present in only small quantities.
