What is this workpackage about?

To understand how space and time might emerge, we need ways to connect two very different scales: the extremely small (the Planck scale) and the much larger scales of the early Universe. This is not easy, and we need both powerful computational tools and quantities that we can calculate and compare with real observations. In this workpackage, we focus on studying patterns of how different parts of space and matter are related to each other. These patterns, called correlations, can reveal how the underlying structure of spacetime behaves at different scales. We investigate how these correlations behave in the deep quantum world, where the rules of physics are very different from our everyday experience. We then try to connect them to the kinds of patterns we observe in the Universe today, such as the tiny variations that eventually led to the formation of galaxies and other cosmic structures.
