And of course there's also been the other recent news about possible indications of a discovery of Dark Matter from detectors floating above Antarctica. http://www.iht.com/articles/2008/11/25/healthscience/25dark.php Could Dark Matter somehow permit new technologies or applications? What practical things could we do with Dark Matter? Does Dark Matter interact with itself? If so, then via what force? Is it possible to have macroscopic bodies of Dark Matter? Can Dark Matter be densified? ie. could these WIMPy Dark Matter particles be clumped together until they created a body sufficiently dense that it would have significant EM interaction? If Dark Matter has gravitational pull, then could we use it to manipulate gravity?
