Finding the God Particle
CERN's LHC Searches for the Higgs Boson

The Standard Model in particle physics is incomplete. The theories that make up the Standard Model cannot explain why matter has mass. Scientists have been trying to solve this problem, and their best hope at finding the answer is the Large Hadron Collider (LHC) that is part of the European Organization for Nuclear Research's particle physics laboratory outside of Geneva, Switzerland. (CERN is the acronymn for the French name for the European Organization for Nuclear Research.)
What Is the God Particle?
The God Particle is a nickname given to the Higgs Boson. The God Particle is enigmatic in that it is everywhere, but no one has seen it. This particle, first proposed by British physicist Peter Higgs in 1964, is believed to be the source of all matter's mass.
The Higgs Boson is the missing piece in the Standard Model of particle physics. If the LHC can find the Higgs Boson, it will solidify the Standard Model. However, if the Higgs Boson cannot be found, or if something completely different is found, it could undermine the Standard Model and cause scientists to go back to the drawing board. Discovering the Higgs Boson will help scientists understand the fundamental laws of nature and describe the workings of the Universe.
What Does the Large Hadron Collider Do?
The Large Hadron Collider is an extremely ambitious project that has been decades in the making. The "Doomsday Machine," as some have termed it, lies 300 feet underground beneath the Swiss-French border. Fear from a few has surrounded the project. Some scientists theorize that the LHC could create microscopic black holes. But physicists calmly explain that if any black holes came into being, they would be too weak to create a problem and would evaporate nearly instantly.
The LHC is the world's largest particle accelerator. This underground bunker consists of a giant 17-mile ring with gigantic superconducting magnets. These magnets are the coldest place in the known universe at -456 degrees Fahrenheit. Absolute zero, the temperature at which all motion ceases, is -459.67 degrees Fahrenheit. In comparison, the cosmic microwave background radiation is approximately 2.7 K, or -454.81 degrees Fahrenheit.
When the LHC is operating, it will accelerate protons around the ring at velocities nearing the speed of light. The protons will race in opposite directions around the seventeen-mile tunnels eleven thousand times per second until they crash into each other, exploding open and revealing their mysterious insides. The high energies created will mimic the conditions that existed a millionth of a billionth of a billionth of a second after the Big Bang.
Although the LHC already performed its first test run on September 10, 2008, the news from CERN is so far anticlimactic. The good news first is that the Earth was not destroyed as a handful had believed. But the Higgs Bosons have not come dancing out yet either. The process is a complicated one. A huge volume of data must be analyzed after each experiment, and the analysis could take years. At the soonest, any discovery as to true nature of the God Particle still lies a few years down the road.
