The European Organization for Nuclear Research, known as CERN, has its offices on the outskirts of Geneva, in an area once devoted to dairy farms and now given over to sprawl. The offices occupy several dozen buildings, some of them in Switzerland and the remainder, a few hundred yards away, in France. The buildings are reachable by roads with names like Route Bohr, Route Schrödinger, and Route Curie. By the entrance to the complex, there is a museum—nearly empty the day I visited—that attempts to make particle physics comprehensible to the general public. Behind that there is a park where bits of old cyclotrons are displayed, like playground equipment from Mars. If you think of the sciences as a tower, with one field resting on another until you reach, say, botany or physiology, then particle physics represents the bottommost floor. Crash Course
The Large Hadron Collider! The marvels of modern technology and the fundamental quest of the human spirit enable us to build an incredible über-accelerator to probe the very nature of reality, and fundamental flaws in the human psyche allow people to ask "How can I make money off this?" Also, "How can I exploit mistrust of scientists to create great headlines - and thereby make money off this?" 1. Five Myths About the Large Hadron Collider
Coordinates: The Large Hadron Collider (LHC) is the highest-energy particle collider ever made and is considered as "one of the great engineering milestones of mankind". It was built by the European Organization for Nuclear Research (CERN) from 1998 to 2008, with the aim of allowing physicists to test the predictions of different theories of particle physics and high-energy physics, and particularly prove or disprove the existence of the theorized Higgs particle and of the large family of new particles predicted by supersymmetric theories. The Higgs particle was confirmed by data from the LHC in 2013. The LHC is expected to address some of the unsolved questions of physics, advancing human understanding of physical laws. It contains seven detectors each designed for specific kinds of exploration.
After overcoming some hurdles, researchers operated the Large Hadron Collider at its highest energy level yet on Tuesday, gathering data after smashing protons into each other. The huge underground particle accelerator at CERN, the European Organization for Nuclear Research in Geneva, is designed to probe the nature of dark matter, antimatter, and an elusive particle called the Higgs boson, as well as any number of physics issues about how those things relate to the history of the universe. "We have observed the first collisions [and] lots of beautiful tracks. It's really fantastic," said a representative of one of the LHC's experiments, called Atlas, during a live Webcast of the event. The tracks are produced by particles created when the LHC's protons collide. A delay set back by about two hours the attempt to push the accelerator to an energy level of 7 trillion electron volts (7 TeV), with two beams each operating at 3.5 TeV. LHC experiments run at highest energy level yet
LHC simulates the epic hotness of colliding neutron stars Want to know what's hot? I'll tell you what's hot. CERN's Large Hadron Collider has smashed lead ions together so fast that they generated temperatures 100,000 times hotter than the center of the Sun. Burnt s'mores, anyone? This quark gluon plasma that the LHC created is not only the hottest and densest soup of subatomic particles ever seen on Earth, it's also the same kind of stuff that existed just a few milliseconds after the Big Bang and helped kick-start the entire universe. That's all pretty impressive, I know, but I imagine by this point you're probably wondering what quark gluon plasma has done for you lately.
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
