chill writes "CNN is reporting that "Scientists have discovered evidence that hordes of dark, miniature galaxies surround ordinary galaxies, lending credence to the theory that the universe is comprised mostly of cold, dark matter." The study was partly funded by NASA and the U.S. DOE."

It's looking more and more like the perennial complaints by cosmologists and other physicists and astronomers that there's too much mass in the universe for it all to be accounted by visible galaxies, is holding true.
Yes, the mass of certain neutrinos and other "nearly-massless" particles does figure in, just like we've been theorizing and hearing for a long time. However, we are continually finding more and more of this evidence that there are other sources of mass in dark matter.
It'll be interesting to see the theories on what these "dark matter galaxies" are. Is it some form of dark baryonic matter? Or something else? Quite exotic, either way...
