A Breakthrough in Measuring the Elusive Weak Nuclear Force A few weeks ago, a groundbreaking experiment successfully measured ...

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

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

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 ...

New research suggests time could hold the key to resolving mysteries of gravity, quantum mechanics, and other phenomena in ...

From pacing out distances with our feet to defining the kilogram by the Planck constant, measurement has come a long way. Across history, humans have sought consistent ways to compare, quantify, and ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

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 ...
