Combined with a higher rate of proton collisions, the new setup allows scientists to further investigate the Higgs boson, following its discovery in 2012.
"When it's a nice starry evening, and you look up to the sky, everything you see there is only 5 percent of what's out there. The other 95 percent is still not understood," says Rende Steerenberg, CERN's head of the operations group within the Beams Department. "It would be very good if we could find hints of what this dark matter is, and perhaps find a dark matter particle."
During an experiment in the accelerator, twin beams of protons travel at close to the speed of light in opposite directions in the collider. They meet in the middle, where invisible fireworks happen-protons smash into each other, creating subatomic particles.
The COVID-19 pandemic delayed a long shutdown for maintenance and upgrades, but here's a look at what it takes to fire the collider back up after a brief hiatus to discover new things in the world of particle physics.
MAGNET-TRAINING // You can't just start up the LHC like a car engine. Getting ready to start up the collider involves literally tens of thousands of tests, Steerenberg says. The most time-consuming part is superconductor magnet-training.

ONE OF THE 'GREATEST THREATS' TO THE PACIFIC NORTHWEST ISN'T WHAT YOU THINK.
EXPERTS ARE PREPARING THE REGION AGAINST THE THREAT OF DANGEROUS VOLCANIC MUDFLOWS, KNOWN AS LAHARS, WHICH COULD INUNDATE THE COMMUNITIES SURROUNDING MT. RAINIER IN AS LITTLE AS 30 MINUTES.
THE WORLD'S TOUGHEST ROW
They rowed 3,000 miles across the Atlantic, battling unpredictable weather, chaotic seas, and finicky equipment. But what they discovered gave them profound new insights into the power of the ocean.
HOW TO DIY OFF-GRID SOLAR
SPEND THE TIME UP FRONT AND PLAN IT CAREFULLY TO AVOID DISAPPOINTMENT
Are We on the Verge of an ARMS RACE in SPACE?
RUMORS OF A RUSSIAN SPACE NUKE, ALONG WITH OTHER SATELLITE-TARGETING WEAPONS, HAVE MADE GEOPOLITICAL TENSIONS EXTEND INTO ORBIT.
Fresh Fingerprints on an Ancient Statue
A CLAY FIGURINE HAS SPENT MILLENNIA incomplete, waiting at the bottom of a lake for its long-dead craftsman to finish the Iron Age-era statuette.
Quantum Entanglement in Our Brains
IT HAS LONG BEEN ARGUED THAT THE human brain is similar to a computer. But in reality, that's selling the brain pretty short.
The Tools of Copernicus
WAY BACK IN 1508, WITH ONLY LIMited tools at his disposal, Nicolaus Copernicus developed a celestial model of a heliocentric planetary system, which he described in hist landmark work De revolutionibus orbium coelestium. It was a complete overhaul of our conception of the universe-one that, unfortunately, earned him the ire of the Catholic church for decades after his death-and forever changed the way we look at the stars.
Building a Sixth-Generation Bomber Raptor
THE GLOBAL COMBAT AIR Programme (GCAP)-a project by the U.K., Italy, and Japan to develop a sixth-generation stealth fighter-has been busy at the drawing board reshaping its vision of the future of air warfare. And judging by the new concept model unveiled at this year's Farnborough air show, that future has big triangular wings.
The Electroweak Force of the Early Universe
TODAY, THE UNIVERSE AS WE KNOW IT IS governed by four fundamental forces: the strong nuclear force, the weak nuclear force, electromagnetism, and gravity.
This Ancient Fossil With a Brain and Guts
WE KNOW WHAT FOSSILS LOOK like. For example, typical dinosaur fossils are bones turned to stone and preserved from the passage of time, located, if we're particularly lucky, in large collections that can be reassembled to represent the beast they used to prop up in their entirety.
