Important phenomena in early universe cosmology ("Big Bang") and collison experiments of heavy nuclei ("Little Bangs") involve quantum fields far from equilibrium. A prominent example concerns the role of nonequilibrium instabilities for the process of thermalization after these "Bangs". Instabilities also arise in many other areas, such as dynamics of ultra-cold quantum gases. Though their origin can be very different, the subsequent evolution after an instability follows universal patterns. They lead to strongly correlated systems, even if the underlying microscopic theory is weakly coupled. I will discuss our current understanding and explain why these far-from-equilibrium systems represent a beautiful example of how complexity can lead to simplicity.
