Description
The maps of the Universe made by cosmic surveys are classical, both in principle and in practice. This obscures the quantum origin of structure our Universe from inflation but simplifies the physical interpretation of the observables. I will review recent progress in connecting observable quantities measured in current and future surveys to deeper principles about the structure of physical laws. I will also discuss how the quantities relevant to cosmological correlators manifest themselves in other observables in cosmological and asymptotically flat backgrounds.
