The muon collider was once dismissed as impossible, but is now gaining steam as the successor to the Large Hadron Collider.

In a collider ring on Long Island, physicists have turned a long standing thought experiment into hard data, watching new particles emerge from what once looked like empty space. By tracing the birth ...

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 ...

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 ...
