'Why the LHC' - www.CERN: "Einstein showed that the three dimensions of space are related to time. Subsequent theories propose that further hidden dimensions of space may exist; for example, string theory implies that there are additional spatial dimensions yet to be observed. These may become detectable at very high energies, so data from all the detectors will be carefully analysed to look for signs of extra dimensions." 'Extra Dimensions' - www.CERN: “We’re essentially guaranteed that there’s going to be something surprising,” Arkani-Hamed said of the Large Hadron Collider, which will operate inside a 17-mile circular tunnel.
