Scientists are getting ready to flip the switch on the largest science experiment ever conducted on Earth — the Large Hadron Collider at the European Organization for Nuclear Research, or CERN.
The LHC is a 27-kilometer ring located in the outskirts of Geneva, Switzerland, around which high-energy protons will be smashed together in two counter-rotating beams. More than 1,000 magnets will keep the beams — each containing millions of protons — on a circular path around the collider, while hundreds more keep the beams focused. The beams will travel at almost the speed of light.
What’s the point? To replicate as closely as possible conditions in the universe immediately after the Big Bang, and to search for the elusive Higgs boson, an undiscovered particle that is required for physics’ Standard Model to work. The Higgs boson — popularized as “God’s particle” — was theorized in 1964 by Peter Higgs and independently by a number of other physicists.
Public Fear and Worry
The LHC experiments may enable scientists to observe a number of theorized aspects of the early universe. For one thing, 96 percent of the universe consists of so-called dark matter and dark energy. “They are incredibly difficult to detect and study, other than through the gravitational forces they exert. Investigating the nature of dark matter and dark energy is one of the biggest challenges today in the fields of particle physics and cosmology,” CERN explained on its Web site.
The experiments may even be able to detect whether extra dimensions of space exist, as theorized by the “string theory” in theoretical physics.
But the collider has been the subject of intense fear among the public. Public-relations staffers at the LHC are receiving a flood of worried and angry phone calls and e-mails, reported James Gillies, head of PR for the collider. Nobel prize winner…
