Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

A decade-long effort to measure one of physics’ most fundamental constants culminates in a moment of uncertainty and ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

Physicists have measured the mass of one of the universe’s basic building blocks, the W boson particle. The new calculation, made at the Large Hadron Collider (LHC) near Geneva, could help solve a ...
