I will show how a Grassmannian turns out to be the natural kinematic space for describing correlation functions of massless spinning particles, in four dimensional (Anti)-de Sitter space.
In this kinematic space, tree-level cosmological correlators factorize in a simple way and can be bootstrapped with rather ease, revealing some hidden beauty.
