2009 promises to be a big one for all things science and tech-related. From the LHC's big comeback to SciFi blockbuster sequels, you heard it here first. We bring you "The Future Now," and we don't mess around.

Construction on the $10-billion behemoth—housed 300 feet underground in a 17-mile circular tube—spanned 14 years and required the efforts of 10,000 engineers and physicists. But its real engineering feat comes from the 1,200 magnets—each 35 tons in weight, 50 feet long, and powerful enough to crush a bus between them—that steer a stream of protons traveling at nearly the speed of light. These magnets are powered by 4,700 miles’ worth of superconducting niobium-titanium cable, and work only when cooled to 3.4˚F above absolute zero, colder than deep space. [ Read Full Story ]

Nine days after the Large Hadron Collider (LHC) turned on its proton beam for the first time, the LHC needed to be turned off. Over the weekend the agency running the Collider announced that an accident damaged the magnets that guide the beam, putting the LHC out of commission for at least two months as scientists work to repair the equipment.

Last Wednesday, after years of construction and months of planning, the Large Hadron Collider, which you just might have heard about, turned on its proton beam for the first time. At the same time, a team of Greek hackers was planning to break through the security of the world’s largest experiments. First reported by the British newspaper the Telegraph, the attack targeted a project website, defacing the website with a long message in Greek.

The purpose of the LHC is to get lots of protons moving very, very fast. The magnet system is the core piece of technology that makes this happen. More than 1,200 magnet sections, each weighing 10 tons, bend proton beams through vacuum pipes around the 17-mile-long underground tunnel near Geneva. Since these protons are going so fast—99.9999991 percent of the speed of light—superconducting coils of niobium and titanium must produce a magnetic field that’s about 200,000 times as strong as Earth’s to bend them.

Today’s most ambitious scientific instruments are modern-day cathedrals in their size and complexity, if not in their purpose—these are, after all, structures built to shatter worldviews, not to reinforce them. And the grandest of all, pictured on these pages and fired into action today, will take us on a journey to one of the least-accessible places imaginable: the realm of quantum particles, less than a billionth the size of a single atom.

The proton is a persistent thing. The first one crystallized out of the universe's chaotic froth just 0.00001 of a second after the big bang, when existence was squeezed into a space about the size of the solar system. The rest quickly followed. Protons for the most part have survived unchanged through the intervening 13.8 billion years—joining with electrons to make hydrogen gas, fusing in stars to form the heavier elements, but all the while remaining protons. And they will continue to remain protons for billions of years to come.

If you somehow managed to avoid seeing the comic, listening to the rap or reading anything in the all out media blitz, then let me be the first to tell you that earlier today the Large Hadron Collider (LHC), the world’s most power particle accelerator, began operation. Scientists hope that the experiments conducted in the $9 billion dollar accelerator will help them discover the mysterious Higgs boson. The Higgs boson, colloquially referred to as the “God particle,” is the hypothetical particle that imbues matter with mass, and finding it (or not finding it) will have profound implications on the world of physics.

Luckily, for those just becoming aware of this momentous event and those wanting to brush up on their LHC knowledge before tackling a cocktail party tonight, Popular Science has you covered. First, start by taking a virtual tour of the accelerator, courtesy of Peter McCready.

If you’re one of the few people who still believes the Large Hadron Collider (LHC) could accidentally destroy the world, I’d recommend you get your affairs in order before September 10th. CERN, the European physics agency that oversees the LHC, has announced that the proton beam in the world’s most powerful collider will be turned on for the first time this September.

Well, it's never a great idea to stand next to a machine that could create black holes, but the magnets that steer the proton beams around the planet's most powerful particle accelerator would probably spare you from excess radiation. Then again, there is the off chance that some 300 trillion protons could erupt from the device and kill you on the spot.

The Large Hadron Collider, the giant particle accelerator that's scheduled to begin colliding protons in August, has the potential to produce the long-sought Higgs boson. That elusive particle is a missing link in the commonly accepted model of physics. Observing it would be an important milestone in our understanding of the fundamental forces of the universe.
