Although it makes up about 85 percent of all matter in the universe, dark matter is frustratingly hard to pin down. In order to figure out what it is, much of the search is about ruling out what dark matter isn't, and now physicists at Stanford and the SLAC National Accelerator Laboratory have narrowed it down further.
