Nearby on the continent, an international team of neutrino researchers is hard at work on IceCube, a massive “crystal ball” of thousands of detectors dangled two kilometers deep within the ultrapure ice sheet. In the next 10 years, the scientists hope to capture a million of the elusive subatomic particles as they bombard Earth at energies higher than those produced in the laboratory, explained Francis Halzen, a professor of physics at the University of Wisconsin.
