... GSAOI Home . ... Science . ... It is widely accepted that the evolution of the large scale structure of the Universe is driven by dark matter. Understanding this dark matter continues to be one of Astronomy's great unsolved problems. Measuring the bulk motions of galaxies allows us to map the overall mass distribution of the Universe in a way that is independent of the luminous matter in galaxies. ...
