Deep Science
America's Underground Lab hosts world-leading experiments deep underground, seeking answers to some of the most profound mysteries of the universe.
World class Underground Research at SURF
Scientists study mysterious particles like neutrinos and dark matter deep underground where a mile of rock shields experiments from cosmic radiation that constantly bombards Earth. We also host biologists, geologists, and engineers, too.
Deep Impacts economic, education, science
SURF makes major impacts on the economy, education and in science.
Breakthroughs in Dark Matter
Most of the mass of the universe is missing. Where is it and how do we know it exists? Scientists working deep underground at SURF believe WIMPs (weakly interacting massive particles) could be the answer.
Unlocking the Secrets of Neutrinos
This ghostly particle could answer a lot of questions about the universe, including how the universe was formed and why we exist.
