论文摘要
在本文中，我们概述了量子重力研究的一些现有问题。我们还介绍了导致Padmanabhan考虑路径积分中的双重性属性的基本想法。这种二元性与字符串理论中的T偶尔性一致。更重要的是，路径积分双重性揭示了任何量子几何形状的通用特征，即存在零点长度$ l_0 $。我们还评论了最近的发展，旨在暴露强度电动力学和黑洞中零点长度的影响。有理由相信，可以通过单个参数（例如$ l_0 $）来描述量子重力现象的主要特征。
In this paper, we present an overview of some of the existing issues of the research in quantum gravity. We also introduce the basic ideas that led Padmanabhan to consider a duality property in path integrals. Such a duality is consistent with the T-duality in string theory. More importantly, the path integral duality discloses a universal feature of any quantum geometry, namely the existence of a zero point length $L_0$. We also comment about recent developments aiming to expose effects of the zero point length in strong electrodynamics and black holes. There are reasons to believe that the main characters of the phenomenology of quantum gravity may be described by means of a single parameter like $L_0$.
