基本尺度的存在被认为是量子引力的一个关键特征。许多方法将此属性作为起始假设。在这里，相反，我们采取了一个不太传统的观点的基础上的基本原则和运动规律的关键检查。我们指出，严格的参数表明更迫切需要修改已知的理论，将一个基本的加速度尺度已经在平坦的空间。互惠原则自然可以做到这一点。除了注意到与弦理论的联系，我们认为互易原理意味着爱因斯坦-希尔伯特作用量的无限导数推广，使引力相互作用从根本上非定域，从而提供了一个指导原则，可以引导我们制定一个一致的量子引力理论。
The existence of a fundamental scale is expected to be a key feature of quantum gravity. Many approaches take this property as a starting assumption. Here, instead, we take a less conventional viewpoint based on a critical inspection of both fundamental principles and kinematic laws. We point out that rigorous arguments suggest a more urgent need to revise known theories to incorporate a fundamental acceleration scale already in flat space. The reciprocity principle can naturally do so. In addition to noticing links with string theory, we argue that the reciprocity principle implies an infinite-derivative generalization of the Einstein–Hilbert action that makes the gravitational interaction fundamentally nonlocal, thus providing a guiding principle that could lead us towards the formulation of a consistent theory of quantum gravity.
