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.
Our universe came to life nearly 14 billion years ago in the Big Bang -- a tremendously energetic fireball from which the cosmos has been expanding ever since. Today, space is filled with hundreds of billions of galaxies, including our solar system's own galactic home, the Milky Way. But how exactly did the infant universe develop into its current state, and what does it tell us about our future?
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.
