After two years of upgrades and repairs, CERN’s Large Hadron Collider in Geneva, Switzerland fires up again this month. This time it’s moving at twice the energy, looking for dark matter and exotic new particles.
Scientists announced on Wednesday they have evidence of the much sought-after Higgs boson, a subatomic particle thought to endow all other particles — and by extension all matter in the universe — with mass. Tom Clarke of Independent Television News reports. Continue reading
What exactly is the Higgs boson, and why is its discovery so fundamental to understanding particle physics? Author and Guardian science correspondent Ian Sample has the details. Continue reading
Disappointed scientists learned this week that the Large Hadron Collider — the most powerful particle collider ever built — will be shut down until next spring after an electrical glitch sparked a helium leak in the machine’s 17 miles of tunnels. Continue reading
Scientists fired a beam of protons around a 17-mile, multi-billion dollar track today — a successful first run for the world’s most powerful particle accelerator. Continue reading
Stretching 17 miles around, a mammoth machine that straddles the Swiss-Franco border will soon start launching the biggest experiments ever attempted in high-energy physics. Continue reading
