  Intriguing parallels between density fluctuation power versus wavenumber on
small (mm) and large (Mpc) scales are presented. The comparative study is
carried out between fusion plasma measurements and cosmological data. Based on
predictions from classical fluid turbulence theory, we argue that our
observations are consistent with 2D turbulence. The similar dependencies of
density fluctuations on these disparate scales might indicate that primordial
turbulence has been expanded to cosmological proportions.
