In its infancy, the universe was awash in fundamental particles. Over billions of years, matter cooled and clumped into stars and galaxies, tied together by a cosmic web of dark matter.

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.

Working at the forefront of particle physics, SLAC scientists use powerful particle accelerators to create and study nature’s fundamental building blocks and forces, build sensitive detectors to search for new particles and develop theories that explain and guide experiments.

In the largest dataset ever collected by a dark matter detector, LUX-ZEPLIN's latest results provide the strongest constraints on low-mass WIMPs and detect boron-8...

Vera C. Rubin Observatory will conduct the 10-year Legacy Survey of Space and Time (LSST), which will collect 60 petabytes of data to address...

The latest results combined weak lensing and galaxy clustering and incorporated four dark energy probes from a single experiment for the first time.
