It’s been online for a month or so now, but I wanted to draw your attention to this article on the Wired site about dark matter – and the search to establish (a) if it exists on anything other than a theoretical level and (b) where the hell all the matter actually is.

Unsurprisingly, the article doesn’t end with a conclusion, as this is ongoing work, but I nonetheless recommend it to you, if only for the brain-bending ideas behind it.
