French and Italian scientists are planning a large underground laboratory beneath the Alps designed to detect elusive particles from the Sun's core. It would consist of a huge tank filled with several hundred thousand cubic metres of ultra-pure water. Detectors lining the tank would be sensitive to flashes of light caused by the passage of sub-atomic particles. The lab would test theories in solar physics and help scientists understand the fundamental forces of nature. Sun stream It would be built adjacent to a road tunnel under the Frejus mountain near the French-Italian border. The ambitious project has entered its earliest...
