At first sight, cold atoms and cosmology could not be more different; they are characterized by vastly different physical scales in energy, length, and time. On page 1213 of this issue, Hung et al. (1) report on the observation of acoustic oscillations in the time evolution of an ultracold quantum degenerate gas. This suggests that similar fundamental physics principles govern aspects of their nonequilibrium evolution.
