The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

A new probe of the humble electron may provide insight into the forces at work inside the heart of matter. Now, the MOLLER experiment at the U.S. Department of Energy's Thomas Jefferson National ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

A team of Brown University researchers developed a technique that uses tiny polymer spheres to sense the forces at play as body tissue forms and grows. A new technique developed by Brown University ...

The original version of this story appeared in Quanta Magazine. A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable ...
