As in where is this dark matter? It is those two questions that have plagued physicists for decades. Dark matter, by its own definition cannot be seen, hence its name. So how do we "see" it, how do we know "where" to look?

Physicists have been trying to think of various "indirect" ways to "see" dark matter for decades. Now physicists at the Institute for Advanced Study in Princeton, NJ and the Max Planck Institute for Physics in Munich are ready to test their methods, The Economist reports...
