Abstract: As cosmologists we wish to learn about the mysteries of the origin, composition, evolution, and fate of the cosmos from all the information the sky has to offer: the cosmic microwave background, galaxy surveys, exploding stars, and reverberations of space-time caused by colliding black holes and neutron stars. How can we distill relevant cosmological information from these data sets? I will argue that this requires nothing less than a new way to connect cosmological theory, simulation, and data. New cosmological tests and advances in Artificial Intelligence (AI) and Machine Learning allow us to design simulation-based, full-physics modeling approaches to cosmology. I will describe the first fundamental insights into cosmological information we have obtained with AI and the current status and challenges of this new way of doing cosmology. I will finish by outlining a path forward that powerfully combines data, theory, computation, Bayesian statistics, and AI. The goal is to reconstruct the detailed initial conditions of the universe at the cosmic beginning, and to probe the formation of cosmic structure and the nature of dark matter and dark energy much more completely than ever before.
