The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to ...

The mass of an object tells you how heavy something is. You can measure mass in grams (g) and kilograms (kg). Light items, like apples and bananas, are measured in grams. Heavy objects ...

Nearly four decades ago, researchers at CERN identified a massive, electrically neutral particle known as the Z boson. This ...

The shift will most notably affect the kilogram, the base measure of mass and the last member of the International System of Units still defined by a physical object. Current efforts are under way ...

Now, a group of astronomers has finally made a precise measurement of the star's mass and settled a 100-year-old debate, using a cosmic phenomenon first predicted by Albert Einstein. The ...

Which confirms other estimates made on Stein-2051B’s mass. With that confirmation, scientists now have a new way to measure the mass of other stars in the cosmos. The infographic below has the ...

Though the stars were thousands of light-years apart, measuring how the more distant star appeared to skirt the oncoming object allowed researchers from Canada and the U.S. to obtain an accurate ...
