The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

An analysis of several experiments aimed at detecting the mysterious neutrino has identified a hint of a crack in the ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

The search for dark matter has been largely unsuccessful so far. But now, scientists think they know where to look for it.

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Hints of a new fundamental interaction are starting to look less like statistical ghosts and more like a pattern that refuses ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...

The Standard Model describes three fundamental forces in nature: electromagnetic, strong and weak. Each force operates through the action of "carrier particles." For example, the photon is the force ...
