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.
