论文摘要
虫洞是爱因斯坦一般相对论的出色解决方案。他们是由莫里斯（Morris）和索恩（Thorne）在1980年代后期进行的，他们弄清楚了一个食谱，即虫洞必须服从才能穿越，即被旅行者安全地越过。一个了不起的特征是，{\ it Exoticaties}必须填充一般相对论理论虫洞，莫里斯（Morris）和索恩（Thorne）将其定义为满足$ -P_R>ρ$的物质，其中$ p_r $是径向压力，$ρ$是蠕虫的能量密度。在本文中，我们在文献中首次介绍了爱因斯坦非模块性重力理论的可穿越的虫洞解决方案。爱因斯坦本人提出了单模型的重力，作为该田间方程是一般相对性场方程的无可迹象的理论。后来，温伯格表明，这种方法优雅地产生了臭名昭著的宇宙学恒定问题的解决方案。这里提出的虫洞解决方案满足了“遍历性”的指标条件，并明显地逃避了异国物质条件，因此我们可以肯定，普通物质可以填充单模型的重力虫洞。
Wormholes are outstanding solutions of Einstein's General Relativity. They were worked out in the late 1980's by Morris and Thorne, who have figured out a recipe that wormholes must obey in order to be traversable, that is, safely crossed by travelers. A remarkable feature is that General Relativity Theory wormholes must be filled by {\it exotic matter}, which Morris and Thorne define as matter satisfying $-p_r>ρ$, in which $p_r$ is the radial pressure and $ρ$ is the energy density of the wormhole. In the present article, we introduce, for the first time in the literature, traversable wormhole solutions of Einstein's Unimodular Gravity Theory. Unimodular Gravity was proposed by Einstein himself as the theory for which the field equations are the traceless portion of General Relativity field equations. Later, Weinberg has shown that this approach elegantly yields the solution of the infamous cosmological constant problem. The wormhole solutions here presented satisfy the metric conditions of "traversability" and remarkably evade the exotic matter condition, so we can affirm that Unimodular Gravity wormholes can be filled by ordinary matter.
