Dark Matter Filament Finally Found

Posted by samzenpus on from the there-it-is dept.

An anonymous reader writes "Everyone is talking about the recent Higgs boson announcement by the scientists at CERN, but another significant scientific discovery was revealed this week as well. In a study published online in the journal Nature on Wednesday, scientists show that they have successfully found the first dark matter filament."

    Non-luminous normal matter absorbs light (and so becomes luminous normal matter evenutally, at least at some frequency).

    BTW, the confirmation for dark matter vs other theories for galaxy rotation came from the WMAP data. IIRC, about 80% of the early matter of the universe was shown to be somehting that interacted gravitationally, but did not interact with light (or electrons). The actual % of dark matter measured matched the amount predicted by the dark matter hypothesis for galaxy rotation rates, which is a pretty convincing confirmation IMO.

    I'd call this bigger than the Higgs.
