Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Scientists at CERN, the home of the Large Hadron Collider, have just observed an astoundingly rare phenomenon at the subatomic level that could lead to a new understanding of the standard model of ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics. Particle’s surprise mass threatens to upend the standard ...

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 ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

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