The smallest pieces of the universe are governed by a beautiful and mind-blowing set of rules: the “Standard Model.” The Standard Model explains the behavior of all 17 discovered particles, and it ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Call off the guard dogs. No one — yet — has to worry about researchers drastically tinkering with the standard model of particle physics, the wildly successful theory that describes how elementary ...

Scientists have made a particle physics discovery that they say could mean nothing less than the upheaval of our entire model of the building blocks of the universe—if their results can be ...
