It’s official, workers have broken ground on a gigantic international experiment that could change the face of physics and scientists itself. It’s the Long-Baseline Neutrino Facility at Sanford Underground Research Facility in South Dakota, and scientists and dignitaries from around the world were on hand for the July 21 ceremony.

This facility will contain the Deep Underground Neutrino Experiment (DUNE), and it will take 10 years to build her and 1,000 scientists to operate her. It will be used to study the mysterious particles called neutrinos, and it could lead to massive breakthroughs with the potential of altering our understanding of physics. You can watch video about the lab at the bottom of this article.

It’s the largest experiment of its kind in the United States, and is being build at the site of a former large gold mine. Now, it mining for something of a very different value.

“LBNF will be constructed over the next decade, and will be home to the Deep Underground Neutrino Experiment (DUNE),” according to a statement. “Fermilab will send a beam of neutrinos 1,300 kilometers (800 miles) through the earth to a detector that stands nearly four stories tall, built nearly one mile underground and filled with liquid argon. Scientists will study the interactions neutrinos make with argon atoms in a quest to learn more about these elusive yet abundant particles.”
