Title: The Cosmological Grassmannian

Abstract: Massless spinning cosmological correlators are highly nontrivial and their structure is still poorly understood. I will show that four-point correlators can be dramatically simplified using a novel geometric object: the Cosmological Grassmannian. This framework makes key properties manifest—such as symmetries, factorization, and the flat-space limit—and reveals the hidden simplicity of these correlators.
