  We will in this paper report on suggestive similarities between density
fluctuation power versus wavenumber on small (mm) and large (Mpc) scales. The
small scale measurements were made in fusion plasmas and compared to
predictions from classical fluid turbulence theory. The data is consistent with
the dissipative range of 2D turbulence. Alternatively, the results can be
fitted to a functional form that can not be explained by turbulence theory. The
large scale measurements were part of the Sloan Digital Sky Survey galaxy
redshift examination. We found that the equations describing fusion plasmas
also hold for the galaxy data. The comparable dependency of density fluctuation
power on wavenumber in fusion plasmas and galaxies might indicate a common
origin of these fluctuations.
