Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

Researchers have uncovered a counterintuitive phenomenon in collision dynamics: high-speed particles bounce back from wet walls much more strongly than expected. Integrating experimental observations ...

Scientists working on CERN’s ALICE experiment have reported the first observation of a distinctive flow pattern among quarks in proton-proton collisions, a signal long associated with quark-gluon ...
