Abstract: The observed properties of the primordial fluctuations in the cosmic microwave background (CMB) can provide constraints on physical theories in regimes otherwise inaccessible to experiment. The Planck satellite has recently dramatically sharpened our view of the early universe, and provided a window into the origin of cosmic structure. I will describe how the Planck data progress our understanding of the extreme physics of the very early universe, and what we have yet to learn.
