The Quantum Universe in the Planck Era and Beyond (General Public Talk) Over the 25 years from the Planck Cosmic Microwave Background (CMB) satellite go-ahead to our 2018 Legacy release, cosmology became a precision science that established our standard model, full of dark energy and matter as well as "ordinary" matter. I will overview the CMB golden age development, reaching back into the early 80s to our future ambitions. But it is the Planck maps of the ultra-early Universe that I will concentrate on. These reveal a remarkable simplicity in the quantum fluctuations that create the cosmic web of galaxies that we inhabit. This a tale of 4 Plancks: the satellite, Planck's constant for quantum fluctuations and for their Fokker-Planck quantum diffusion, all happening rather near the Planck energy-scale. In future CMB experiments, we are in quest of "beyond the standard model" physics, in more complex density- structures and in gravity-wave fluctuations. Host: Raul Angulo
