The Large Hadron Collider plays with Albert Einstein’s famous equation, E = mc², to transform matter into energy and then back into different forms of matter. The project also cost a fortune. What does it do? How the LHC, one of the most complex machines ever created, is … Why is it there? Large Hadron Collider (LHC), world’s most powerful particle accelerator.The LHC was constructed by the European Organization for Nuclear Research in the same 27-km (17-mile) tunnel that housed its Large Electron-Positron Collider (LEP).The tunnel is circular and is located 50–175 metres (165–575 feet) below ground, on the border between France and Switzerland. Developing The Large Hadron Collider: Things You Need To Know. Following an upgrade, the LHC now operates at an energy that is 7 times higher than any previous machine! And when I say massive, I mean every word of it. Large Hadron Collider. The Large Hadron Collider (LHC) is a marvel of modern particle physics that has enabled researchers to plumb the depths of reality. The Large Hadron Collider (LHC) is by far the most powerful particle accelerator built to date. So, the LHC is the largest and most complicated scientific experiment ever attempted. First, I will like to point out that LHC is massive. Sadly, there's no rapping! Pretty impressive! And looking at the size, landmass, and material that went into its construction, you won’t doubt its cost for a second. The LHC is based at the European particle physics laboratory CERN, near Geneva in Switzerland. The Large Hadron Collider (LHC) has generated mind-blowing science in the last decade – including the Higgs boson particle. The brilliant Large Hadron Rap helped me understand a bit more about it. But on rare occasions, it can skip the first step and collide pure energy—in the form of electromagnetic waves. This video, featuring Professor Brian Cox, does a good job of explaining the LHC too.
