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.

How This Particle Could Break Our Understanding of Reality
EINSTEIN'S SPECIAL THEORY OF relativity teaches us that nothing can accelerate past the speed of light. But what if, when you were born, you were already moving faster than light? What would that look like?
The Right Way to Use a Fire Extinguisher
A FIRE EXTINGUISHER IS MORE THAN A of one 5-gallon bucket becomes the size of 64 burning buckets. Just 180 seconds after it begins, a fire can be transformed from a nuisance to a room-size, life-threatening inferno.
How the World's Largest Spherical Structure Was Built
THE SHINY, NEW LAS VEGAS SPHERE IS more than just a 17,600-seat amphitheaterstyle venue hosting a U2 residency. Since its opening in September 2023, it's become the world's largest spherical structure, at 516 feet wide and 366 feet tall.
The Army's Drone-Killing Laser Weapon
THE U.S. ARMY FIELDED ITS FIRST LASERweapon-equipped unit in October. Based at Fort Sill, Oklahoma, the unit took possession of four laser-equipped Stryker infantry combat vehicles, each mounting a 50-kilowatt-class laser-weapon system. The combination of Stryker and laser can down both artillery, such as mortars and rockets, and drones in-flight.
