DOE provides the majority (approximately 90%) of federal support
for high-energy and nuclear physics research, which uses advanced accelerator
facilities as well as detectors placed underground and in space to understand
the fundamental nature of matter, energy, space, time and the properties and
interactions of atomic nuclei and nuclear matter.
Deciphering the nature of dark matter -- the mysterious substance that makes up about 85 percent of the matter in the universe yet has never been directly seen -- is one of the most important quests in particle physics today. As the lead laboratory in the Department of Energy for the SuperCDMS SNOLAB project, SLAC National Accelerator Laboratory is playing an important role in tracking it down.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
