The world’s largest and most powerful particle accelerator is set smash protons together on April 8 to search for invisible particles secretly powering our universe. Theories have suggested there are 17 different particle groups and the European Organization for Nuclear Research, better known as CERN, confirmed the existence of one using its Large Hadron Collider (LHC) in 2012. Now, the team has restarted the LHC with hopes of unraveling more mysteries of the universe - specifically dark matter. Scientists began preliminary tests by sending billions of protons around the LHC's ring of superconducting magnets to boost their energy and ensure...

width =45%> Particle accelerators are machines that propel charged particles at incredible speeds, generally to collide with other particles. It's highly advisable that the particles the high-speed particles collide with should not be part of your head, as one man learned the hard way. On July 13, 1978, particle physicist Anatoli Bugorski was working his job at the U-70 synchrotron, the largest particle accelerator in the Soviet Union. The 36-year-old was inspecting a piece of equipment that had malfunctioned when the accident happened. Unbeknownst to him, several safety mechanisms had also failed, meaning that when he leaned over to...

On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts of microwave radiation nudge the particles ever-faster forward until their velocity approaches the speed of light, creating a powerful beam that scientists from around the world use to probe the atomic and molecular structures of inorganic and biological materials. Stanford and SLAC have created a silicon chip that can accelerate electrons—albeit at a fraction of the velocity of that massive instrument—using an infrared laser to deliver,...

GENEVA – The world's largest atom smasher has recorded its first high-energy collisions of protons, a spokeswoman said Wednesday. Physicists hope those collisions will help them understand suspected phenomena such as dark matter, antimatter and ultimately the creation of the universe billions of years ago, which many theorize occurred as a massive explosion known as the Big Bang. The collisions occurred Tuesday evening as the Large Haldron Collider underwent test runs in preparation for operations next year, said Christine Sutton of the European Organization for Nuclear Research, or CERN. Two beams of circulating particles traveling in opposite directions at 1.18...

Shortly after the first of the year (if not already), the Large Hadron Collider — the most powerful particle accelerator ever built — will smash protons together at record energies. If the Earth remains intact, doomsayers will once again have been falsified. Every time they forecast the demise of the planet, those prophets of Earthly annihilation prove themselves no more foresightful than mortgage bankers or phony psychics.

The biggest, most expensive physics machine in the world is riddled with thousands of bad electrical connections. Many of the magnets meant to whiz high-energy subatomic particles around a 17-mile underground racetrack have mysteriously lost their ability to operate at high energies. Some physicists are deserting the European project, at least temporarily, to work at a smaller, rival machine across the ocean. After 15 years and $9 billion, and a showy “switch-on” ceremony last September, the Large Hadron Collider, the giant particle accelerator outside Geneva, has to yet collide any particles at all. But soon? This week, scientists and engineers...

The man behind the world’s biggest scientific experiment, which critics claim could cause the end of the world, is a Welsh miner’s son who has admitted blowing things up as a child. Dr Lyn Evans, who has been dubbed Evans the Atom, will this week switch on a giant particle accelerator designed to unlock the secrets of the Big Bang. But the 63-year-old physicist revealed yesterday that his passion for science was fuelled by the relatively small bangs he had created with his chemistry set at his council house in Aberdare in the Welsh valleys.

The video looks a bit like a scene from a low-budget sci-fi horror film. A tiny hole slowly begins sucking in bits of the Earth in Switzerland with mountains, lakes and cities quickly falling into the growing gap. And it just keeps on growing--and growing. By the end of the 38 second movie, the entire planet has been swallowed up -- and all that's left is a shimmering ring in the inky blackness of outer space. Absurd, perhaps. But a brief look around Internet blogs, and especially YouTube, makes it clear that there are a number of people out there...

GENEVA (Reuters) - The world's most powerful particle accelerator, aimed at unlocking secrets of the universe, will be launched on September 10, the European Organization for Nuclear Research (CERN) said on Thursday. The Large Hadron Collider (LHC), housed in an underground tunnel 27 kilometers (17 miles) in circumference, will recreate conditions just after the Big Bang which many scientists believe gave birth to the universe. It will seek to collide two beams of particles at close to the speed of light. "The first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on September 10,"...

A new technique allowing virtual dissections of half-billion-year-old fossil embryos is producing the first three-dimensional images of the dawn of life. It reveals a universe of detail impossible using previous methods, and researchers said it was pushing back the frontiers of science much as the scanning electron microscope did half a century ago. [SNIP] In contrast to those methods, synchroton-radiation X-ray tomographic microscopy, or SRXTM, leaves the tiny fossils untouched but gives graphic details of their structure.
