To explore the birth of the universe, the formation of stars and galaxies and the fundamental structure of space and time, SLAC researchers develop cutting-edge technologies for sensitive experiments located deep underground, on the surface and in space.

SLAC's astrophysicists and cosmologists pursue research in areas identified as top priorities for U.S. high-energy physics for the next decade. They want to understand our universe – from its smallest constituents to its largest structures. Several of these research topics are also covered by SLAC’s particle physics program.
