The Large Hadron Collider, built by European scientists, is expected to bring about the biggest advances in the field of particle physics and other related fields in decades. For some time, tangible advancements in physics lagged behind as the capabilities to experiment theoretical possibilities did not keep up with researchers' desires.

Now, the $10 billion Large Hadron Collider and its ATLAS detector, the world’s largest general-purpose particle detector, are effectively the world's most advanced particle physics experiment, which is also backed by some mega-powerful computers to process the large amounts of data extracted from the detector.

The LHC is all revved up and ready to go Wednesday. Unfortunately for some, no, it won't trigger the end of the world.

In February, the last piece of the ATLAS detector, the world’s largest general-purpose particle detector, has been lowered down a 300 feet shaft at the European Organization for Nuclear Research's (CERN) underground facility along the Swiss-French border. This concluded the construction of the high-tech device which started in 2003.

The ATLAS detector, measuring 46 metres long, 25 metres high and 25 metres wide, will detect and trace particles called muons expected to be produced in particle collisions in the CERN accelerator, known as the Large Hadron Collider (LHC).

The project will look for signs of the Higgs particle, which is believed by some scientists to be responsible for giving other particles their mass. CERN said in its statement that its entire muon spectrometer system contains an area equal to three football fields, including 1.2 million independent electronic channels.

CERN, the Geneva-based European Organization for Nuclear Research, is the world's leading laboratory for particle physics. Its Member States are: Austria, Belgium, Bulgaria, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Netherlands, Norway, Poland, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. The United States is one of the Observers.
