This project aims to image the cosmic microwave background – the oldest light in the Universe – to study what the Universe is made of and how it began. A key mystery in cosmology is what caused inflation: why did the Universe expand exponentially in the first fraction of a second? This project would look for the gravitational wave echoes of inflation to better understand its cause. The project also plans to use gravitational lensing of the cosmic microwave background to map all mass in the Universe across half the sky. A mass map would be invaluable for measuring the sum of the neutrino masses and testing how structure forms in the Universe.

该项目旨在对宇宙微波背景（宇宙中最古老的光）进行成像，以研究宇宙是由什么组成的以及它是如何开始的。宇宙学中的一个关键谜团是什么导致了膨胀：为什么宇宙在一秒钟的前几分之一内呈指数级膨胀？该项目将寻找暴胀的引力波回波，以更好地了解其原因。该项目还计划利用宇宙微波背景的引力透镜来绘制宇宙中一半天空的所有质量。质量图对于测量中微子质量的总和和测试宇宙中的结构如何形成是非常宝贵的。
