Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

Physicists have shown that, like everything else experiencing gravity, antimatter falls downwards when dropped. This outcome is not surprising — a difference in the gravitational behaviour of matter ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Dark matter particles outnumber ordinary matter in the cosmos by about one to five, but scientists don’t yet know what these abundant particles actually are. Thus far, the most heavily favored ...

Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...
