The researchers, working on an experiment called OPERA, beamed neutrinos through the earth's crust, from CERN, the laboratory for particle physics near Geneva, to Gran Sasso National Laboratory in L'Aquila, Italy,
an underground physics lab.
Keen to avoid a similar debacle, CERN, the European particle
physics lab near Geneva, Switzerland, took the momentous decision to cram the LHC into an existing circular tunnel 100 metres
underground, which had been built in the 1980s for the Large Electron Positron (LEP) collider.
