德国科学家测定“幽灵粒子(Ghost Particles)”的质量
Scientists in Germany have flipped the switch on a 60 million euro ($66 million) machine designed to help determine the mass of the universe's lightest particle. The Karlsruhe Tritium Neutrino experiment, or KATRIN, began tests Friday and is expected to begin making actual measurements next year. Physicists at the Karlsruhe Institute of Technology hope the 200-metric-ton (220-ton) device will narrow down or even pinpoint the actual mass of neutrinos (中微子). Doing so would help scientists to better understand the history of the universe. Neutrinos are sometimes referred to as "ghost particles" because they are so difficult to detect.
