Unitarity is a crucial tool in particle physics: for instance requiring physically sensible scattering probabilities provided a bound on the Higgs mass long before it was directly detected. In this talk, I will discuss how unitarity can be similarly applied to field theories of inflation, and show how measurements of primordial non-Gaussianity can be used to bound properties of the new physics on sub-horizon scales.
