Dark Energy is one of the most profound mysteries of modern physics. It makes up about 70 percent of the Universe, but no compelling theory can explain its nature. This project aims to measure the properties of Dark Energy with unprecedented accuracy: an order of magnitude better than the state of the art. It aims to accomplish this by extracting information from the largest 3D map of the cosmos, built with the optical spectra of 35 million galaxies, observed by the Dark Energy Spectroscopic Instrument. This project will foster Australia's historic leadership and investments in galaxy surveys via unique international partnerships, and produce cutting-edge tools for big data analyses with important applications in a wide range of industries.

暗能量是现代物理学最深奥的谜团之一。它约占宇宙的 70%，但没有令人信服的理论可以解释它的性质。该项目旨在以前所未有的精度测量暗能量的特性：比现有技术高出一个数量级。它的目标是通过从最大的 3D 宇宙地图中提取信息来实现这一目标，该地图由暗能量光谱仪器观测到的 3500 万个星系的光谱构建而成。该项目将通过独特的国际合作伙伴关系，培养澳大利亚在星系调查方面的历史性领导地位和投资，并生产在各行各业具有重要应用的尖端大数据分析工具。
