Two teams of physicists compete to explain matter—and win a Nobel Prize.
published online August 13, 2007
Near the west end of Lake Geneva in Switzerland, buried under the river plain of the Rhône, workers are fitting together the final pieces of the machine that hopes to unlock one of the biggest mysteries of the universe. It has taken over 20 years, $8 billion, and the combined efforts of more than 60 countries to create this extraordinary particle smasher, the Large Hadron Collider, or LHC, built and operated by CERN, the European physics consortium.
The “large” in Large Hadron Collider is something of an understatement. “Enormous” is closer: The collider’s underground tunnel carves a circle 17 miles in circumference, traversing the border between Switzerland and France. At four locations it passes through caverns crammed with detectors the size of buildings. In a deliberately constructed rivalry, two of these detectors—along with their armies of scientists, engineers, and technicians—will vie with each other to discover the obscure but wildly important particle known as the Higgs boson.
“The LHC will enable us to study in detail what nature is doing all around us,” said CERN Director General Robert Aymar. “The LHC is safe, and any suggestion that it might present a risk is pure fiction.”
Safety has been an integral part of the LHC project since its inception in 1994, and the project has been subject to numerous audits covering all aspects of safety and environmental impact. A comprehensive report by independent scientists addressing safety issues related to the production of new particles at the LHC was presented to CERN’s governing body, the CERN Council, in 2003. It concluded that the LHC is safe. This report was updated and its conclusions strengthened in a new report incorporating recent experimental and observational data that was presented to Council at its most recent meeting in June 2008. This new report confirms and strengthens the conclusion of the 2003 report that there is no basis for any concern about the safety of the LHC.The CERN Council is composed of representatives of the governments of the 20 European Member States of CERN.
The report was prepared by a group of scientists at CERN, the University of California, Santa Barbara, and the Institute for Nuclear Research of the Russian Academy of Sciences. The papers comprising the report have been accepted for publication in leading peer-reviewed scientific journals. The report was reviewed carefully by the Scientific Policy Committee (SPC), a body composed of 20 independent external scientists that advises the CERN Council on scientific matters. Five of these independent scientists, including one Nobel Laureate, examined in detail the 2008 report and endorsed the authors’ approach of basing their arguments on irrefutable observational evidence to conclude that new particles produced at the LHC will pose no danger. The full SPC agreed unanimously with their findings.
“The LHC safety review has shown that the LHC is perfectly safe,” said Jos Engelen, CERN’s Chief Scientific Officer, “it points out that Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth – and the planet still exists.”

And the latter can speed up certain (or most) discoveries (and the falsification of invalid hypotheses) above...

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.
