在过去的十年里，寻找具有离散物质内容的相对论宇宙学模型的爱因斯坦方程的解已经取得了显著的成果。在这篇综述中，我们讨论了离散宇宙学的一个特定子类——黑洞晶格模型的研究进展。特别是，我们说明了用于构建这些时空的技术，并检查了它们产生的物理性质。这包括它们的大尺度动力学，由于单个黑洞之间的相互作用而导致的质量变化，以及直接观测兴趣的特征，如距离-红移关系。这些结果集合为广义相对论中平均的物理效应以及从孤立物体解中出现的引力结构提供了一个新的视角。
The search for solutions of Einstein’s equations representing relativistic cosmological models with a discrete matter content has been remarkably fruitful in the last decade. In this review we discuss the progress made in the study of a specific subclass of discrete cosmologies, black-hole lattice models. In particular, we illustrate the techniques used for the construction of these spacetimes, and examine their resulting physical properties. This includes their large-scale dynamics, the dressing of mass due to the interaction between individual black holes, along with features of direct observational interest such as the distance-to-redshift relation. This collection of results provides a novel perspective on the physical effects of averaging in general relativity, as well as on the emergence of gravitational structures from solutions with isolated objects.
