This project seeks to reveal the nature of dark energy and thereby explain what is causing expansion of the Universe to accelerate. The project will develop new deep machine learning techniques to weigh galaxy clusters, and apply them to data from the SPT-3G experiment at the South Pole. By comparing theoretical predictions to the observed numbers and masses of galaxy clusters, the project will help determine whether the acceleration is due to dark energy or a breakdown in general relativity. The data science training received by students and researchers on the project will also contribute to a highly skilled STEM workforce for Australia.

这个项目旨在揭示暗能量的本质，从而解释是什么导致了宇宙的加速膨胀。该项目将开发新的深度机器学习技术来衡量星系团，并将其应用于南极SPT-3G实验的数据。通过将理论预测与观测到的星系团的数量和质量进行比较，该项目将有助于确定加速是由于暗能量还是广义相对论的崩溃。学生和研究人员在项目中接受的数据科学培训也将为澳大利亚提供高技能的STEM劳动力。
