In this talk, I will explore a novel way of probing dS horizons using holography. Namely, we studied asymptotically AdS2 solutions that deep in the interior flow to the cosmological horizon of dS2. We calculate various matter perturbations at the linearised and non-linear level. We consider both Euclidean and Lorentzian perturbations. The results can be used to characterise the features of a putative dual quantum mechanics. The chaotic nature of the de Sitter horizon will be assessed and compared to the usual black hole case.
