What is this workpackage about?

When we look at a chair, we don’t usually think about the atoms it is made of. In a similar way, our current theories of the Universe describe what we see on large scales, without necessarily explaining the smallest underlying building blocks. In this workpackage, we ask a big question: could space, gravity, and even the structure of the Universe emerge from something more fundamental?

Today’s cosmological models rely on concepts like dark matter and dark energy to explain how the Universe expands and how structures like galaxies form. While these ideas work well, their true nature is still unknown. We explore whether a new perspective where space and gravity themselves are emergent could also explain these mysterious phenomena. Our research focuses on the deep principles behind how geometry and gravity might arise, as well as the broader implications of this idea, both for physics and for how we understand the Universe.
