The European Organization for Nuclear Research (CERN) said on Monday that repairing the Large Hadron Collider (LHC) will cost up to €16.6 million or $21 million. The LHC, which is the world's largest and highest-energy particle accelerator, is located near the border of France and Switzerland and crosses the border four times. It has a diameter of 27 km (17 miles). It is designed to simulate the conditions shortly after the Big Bang, but it broke down on September 19 due to an electrical failure.
