Large Hadron Collider Is Ready To Re-Start This Weekend | CosmosUp: Underneath some nondescript farmland near Geneva, on the border of France and Switzerland, the world’s biggest and most expensive scientific experiment is ready to re-start. LHC at the Cern laboratory – were preparing to switch it on today for the first time in two years, ahead of the next series of experiments.
Two years ago the team operating the �3.74bn machine straddling the Swiss-French border astounded the world with the discovery of the Higgs boson, an elementary particle that gives other particles mass. Now they have their sights set on an even more exotic trophy – dark matter, the invisible, undetectable material that makes up 84 per cent of matter in the universe and binds galaxies together yet whose nature is unknown.
