论文摘要
弯曲的时空嵌入在较高维度平坦的时空中仍然是相对论一般理论的一个关注的话题，这是诱导物种理论的例证。本文介绍了嵌入一级的空间，即可以嵌入五维平坦时空的空间。爱因斯坦的理论允许第五维度是空位般的或及时的。通过假设后者，本文解决了有关莫里斯 - thorne虫洞的两个基本问题，外来物质的起源以及喉咙上经常无法解释的巨大径向张力。
The embedding of a curved spacetime in a higher-dimensional flat spacetime has continued to be a topic of interest in the general theory of relativity, as exemplified by the induced-matter theory. This paper deals with spacetimes of embedding class one, i.e., spacetimes that can be embedded in a five-dimensional flat spacetime. Einstein's theory allows the fifth dimension to be either spacelike or timelike. By assuming the latter, this paper addresses two fundamental issues concerning Morris-Thorne wormholes, the origin of exotic matter and the frequently inexplicable enormous radial tension at the throat.
