Producing Dark Matter: "“[It’s] mostly made of dark matter and energy, which we don’t really know about,” he tells PhysOrg.com. “The thing about this collider is that it can help us understand dark matter.”

Along with two colleagues, Shufang Su at the University of Arizona, and Fumihiro Takayama at Cornell University in Ithaca, NY, Feng proposes a way to use the massive LHC to produce dark matter in order to study its characteristics. “What we do know is by looking through telescopes,” he says, “and we can tell that galaxies are spinning too fast if all you had is what you saw. They would fall apart without something else. So this is what we know is dark matter. All we know is that it is holding stuff together.” "
