Even though it is not possible to differentiate general relativity from teleparallel gravity using classical experiments, it could be possible to discriminate between them by quantum gravitational effects. These effects have motivated the introduction of nonlocal deformations of general relativity, and similar effects are also expected to occur in teleparallel gravity. Here, we study nonlocal deformations of teleparallel gravity along with its cosmological solutions. We observe that nonlocal teleparallel gravity (like nonlocal general relativity) is consistent with the present cosmological data obtained by SNe Ia + BAO + CC + [Formula: see text] observations. Along this track, future experiments probing nonlocal effects could be used to test whether general relativity or teleparallel gravity gives the most consistent picture of gravitational interaction.
尽管利用经典实验无法区分广义相对论和挠平行引力，但通过量子引力效应有可能对它们进行辨别。这些效应促使人们引入了广义相对论的非局域形变，并且预计挠平行引力中也会出现类似效应。在此，我们研究挠平行引力的非局域形变及其宇宙学解。我们观察到，非局域挠平行引力（如同非局域广义相对论）与通过Ia型超新星 + 重子声学振荡 + 宇宙微波背景辐射 + [公式：见原文]观测所获得的当前宇宙学数据相一致。沿着这条思路，未来探测非局域效应的实验可用于检验广义相对论或挠平行引力是否能给出关于引力相互作用最自洽的描述。
