This project aims to map out the behaviour of gravity across the Universe. This research will address a key gap in our understanding of physics, with significant implications for fundamental theory: we cannot account for the fact that the expansion of the Universe appears to be speeding up. This project will use the largest 3D map of how galaxies are distributed across the Universe, together with complementary datasets tracing the deflections of light -- obtained through unique international partnerships -- to produce a novel description of how Universal gravitation depends on separation and time. This work will provide new limits on allowed deviations from General Relativity (with 2% accuracy), or map out new and unexpected phenomena.

该项目旨在绘制出整个宇宙的引力行为。 这项研究将解决我们对物理学理解的一个关键差距，对基础理论具有重大意义：我们无法解释宇宙膨胀似乎正在加速的事实。 该项目将使用最大的星系如何分布在宇宙中的3D地图，以及通过独特的国际合作伙伴关系获得的跟踪光偏转的补充数据集，以产生对万有引力如何依赖于分离和时间的新颖描述。 这项工作将为广义相对论的允许偏差提供新的限制（精度为2%），或者绘制出新的和意想不到的现象。
