WIDELY SEPARATED LABORATORIES WILL STUDY FUNDAMENTAL FORCES

摘要

In minnesota's far-northern vermillion Iron Range, construction crews are putting finishing touches on an underground physics laboratory nearly a halfmile below grade. More than 400 miles away in Illinois, another team is aiming a 4,000-ft-long tunnel directly at the laboratory. Eventually, subatomic particles generated at the Fermi National Accelerator Laboratory near Chicago will be beamed toward detection equipment in Minnesota, allowing scientists to study fundamental forces of nature.
