A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time ...

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 ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
