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 ...

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 ...

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 ...

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 ...

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

The Muon g-2 Collaboration has doubled the precision of their 2021 measurement of the muon’s magnetic moment and it disagrees with the predictions based on the standard model of physics. Muons are ...

A team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe's age and help physicists and ...

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 ...
