The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

Here’s a Snapple-cap factoid that’d be fun to whip out in conversation: on a planet the size of a ladybug, objects would fall 30 billion times slower than they do here on Earth. And how do scientists ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

Fine balance The researchers measured the gravitational field between two gold masses of 1mm radius each that are brought close to each other. (Courtesy: Tobias Westphal, University of Vienna) ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

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 ...
