对称性、奇点与空间的消失

Symmetries,Singularities and the De-Emergence of Space

Thibault Damour, Hermann Nicolai

摘要:

最近的工作揭示了广义相对论中类空奇点的Belinsky-Khalatnikov-Lifshitz型分析与某些无限维李代数,特别是“最大扩展”双曲卡茨-穆迪代数E10之间的有趣联系。在这篇文章中,我们认为,这些结果可能会导致一个全新的理解(量子)性质的空间(-时间)在普朗克尺度,因此-通过一个有效的“de-emergence”的空间附近的奇点-一个新的机制,实现背景独立的量子引力。

英文摘要:

Recent work has revealed intriguing connections between a Belinsky-Khalatnikov-Lifshitz-type analysis of spacelike singularities in General Relativity and certain infinite dimensional Lie algebras, and in particular the `maximally extended' hyperbolic Kac--Moody algebra E10. In this essay we argue that these results may lead to an entirely new understanding of the (quantum) nature of space(-time) at the Planck scale, and hence -- via an effective `de-emergence' of space near a singularity -- to a novel mechanism for achieving background independence in quantum gravity.
