Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics. Fundamental particles are objects that are so small, they have no deeper ...

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more ...
