A special groundbreaking was held today (July 21) deep underground in South Dakota. Scientists, engineers and guests turned the first shovelfuls of the 800,000 tons of rock that will be excavated to build the Long Baseline Neutrino Facility (LBNF) at the Sanford Underground Research Facility. The cavern will house a giant detector for the Deep Underground Neutrino Experiment (DUNE).
The goal of DUNE is to better understand neutrinos and their role in the evolution of the universe, including why our universe is made of matter and not antimatter. DUNE will also be able to detect neutrinos from deep space, emitted by supernovae or black holes.
