A large number and variety of ongoing and upcoming experiments are mapping the entire structure of the observable universe. This will establish the experimental foundation for the emerging field of density perturbation phenomenology — learning fundamental physics from density perturbation maps. In this talk, I will describe how the measurement of the non-Gaussian statistics of these maps can be used to extract information on the primordial universe, such as the inflation models and supersymmetry.
