At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter. Collisions inside the 27‑kilometer ring have produced what researchers ...

At the world’s most powerful colliders, physicists are finally catching sight of particles that almost never leave a trace, a “ghost” signal that has haunted theory for decades. The detection of these ...

The Large Hadron Collider is entering a rare quiet spell, with its proton collisions halted so engineers can prepare the machine for a more powerful future. The shutdown is not a sign of trouble so ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties and—perhaps oddest of all—particles that spontaneously spring into being from the ...
