In 2012, the physicists at CERN (the European Organization for Nuclear Research), outside Geneva proved the existence of the Higgs boson, the extremely tiny and enormously important sub-atomic particle that gives mass to the matter of the universe we can see.
|The CMS collider will search for dark matter.|
Now, after shutting down in February 2013 for planned maintenance and upgrades, CERN is again powering up its Large Hadron Collider to fling protons in opposite directions around its circular 27-km accelerator at nearly the speed of light before smashing them into each other to form new even tinier sub-atomic particles. And this time, the LHC will be operating at nearly double the beam energy.
Why is more energy important? You can find out in my new article for swissinfo.com:
