The Department of Energy is the primary source of support for physics in the Federal Government. Physics research includes efforts in astrophysics striving to shed light on the dark matter and dark energy that make up 95 percent of our universe. Other efforts focus on Lattice Quantum Chromodynamics, Nuclear structure, turbulence, and preparing for the tidal wave of data that is expected from large physics experiments such as the Large Hadron Collider in Europe. Some of these efforts are partially supported by the National Science Foundation and/or the National Nuclear Security Administration (NNSA).

Nuclear physics research provides new insights to advance our knowledge on the nature of matter and energy. At its heart, nuclear physics attempts to understand the composition, structure, and properties of atomic nuclei. High energy physics strives to understand the universe at a more basic level by investigating the elementary particles that are the fundamental constituents of matter and the forces between them. The study of physics has advanced with the technology to study ever-higher energies and very rare phenomena that probe the smallest dimensions we can see and tell us about the very early history of our universe. While physics has revolutionized our understanding of how the universe works, elements of physics technology have helped transform other fields of science, medicine, and even everyday life. Physics research and its impacts will be remembered as one of the highlights of the history of the late 20th century.
