Quantum scale gravity has long been a mystery to physics, but things could be starting to change. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

There's a trailer out for a new science fiction film called Moonfall, to be released in early 2022, in which the moon is about to crash into Earth. It features several shots of a reddish moon hovering ...

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 ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

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 ...

If the Sun were to spontaneously cease emitting light, we wouldn't know about it for about 8 minutes and 20 seconds. The light that's arriving here on Earth, right at this very moment, was emitted ...
