A study of the spatial autocorrelation of heavy-element-containing absorption systems in QSOs has shown strong clustering. Based on this correlation, it is proposed that more data may facilitate study of large-scale structure at larger scales and earlier epochs than previously possible. It may be possible to measure the slope of the primordial power spectrum, and set a new lower bound on the mass density of the universe in nonrelativistic species, including the unknown dark matter, whether or not it is baryonic.
