Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

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 ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. An international collaboration of ...

For decades, physicists searched for a missing piece of nature's puzzle, an elusive particle believed to explain why matter ...

Europe's physics lab CERN is planning to build a particle-smasher even bigger than its Large Hadron Collider to continue searching for answers to some of the universe's tiniest yet most profound ...

The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all. When you purchase through links on our site, we may earn an affiliate commission.
