LHC: Large Hadron Collider
The LHC is the world largest circular collider build by the European Organization or Nuclear Research (CERN) for high energy physics experiment, and is 28 kilometers in circumference running across the border of Switzerland and France near Geneva. The LHC took 14 years to build, and started running on 10 September, 2008.
The LHC is designed to collide two beams of protons accelerated to 7 tela-electron volts, to see new elementary particle physics in the high energy not yet explored. 100 meter underground sit four major detector sites, which are altogether as large as a 6-floor building and have five detectors. The LHC will test the Standard Model, and also investigate the Grand Unification and Supersymmetry in the long run.
Several lawsuits have been filed against CERN to halt the LHC project in Hawaii and at the European Court of Human Rights, arguing that the high energy collisions can create micro black holes which are capable of swallowing the entire planet we live on. Creation of a micro black hole requires theories that assume at least one additional spatial dimension besides our ordinary three spatial dimensions—up/down, left/right, and forward/backward. This means that if a micro black hole is found in LHC there will be the first major advances in our understanding of space and time since the Einstein’s General Relativity. The CERN explains that produced black holes if any would evaporate soon after the creation, and should therefore cause no harm to the surroundings.
