The Large Hadron Collider (LHC) is a particle accelerator, its main purpose is to explore the validity and limitations of the Standard Model.
The LHC is being built by CERN in collaboration with over 2,000 physicists from 34 countries as well as hundreds of universities and laboratories around the world. The collider is contained in a circular tunnel with a circumference of 27 kilometres at a depth ranging from 50 to 175 metres underground. The total cost of the project is anticipated to be between €3.2 to €6.4 billion, and is expected to generate 15 Petabytes (15 million Gigabytes) of data annually. Starting 2008.
In other words: the LHC is the largest scientific instrument on the planet.
Some people say the LHC is gonna fail and will create a black hole in Switzerland which will eventually destroy the Earth, but everybody knows that The Big Mistake was not an accident. And what the hell, if we blow up the planet this way at least we do it stylishly, and not with this Climate Change shit.
Update: OMG, Da LHC is Superduper Fly!
