It does not resolve the discrepancy, but it gives physicists one more data point in their ongoing quest to nail down a more ...

Earth’s gravitational force, g, has been known for centuries. But the exact value of G, the universal gravitational constant, ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

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

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

In the quest to measure the fundamental constant that governs the strength of gravity, scientists are getting a wiggle on. Using a pair of meter-long, vibrating metal beams, scientists have made a new ...

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and ...

The Arecibo Observatory in Puerto Rico, one of the radio telescopes used to detect the pulses from pulsars in the new research. The telescope started to fall apart in 2020 and was decommisioned.

New ‘gravity mapping’ hardware could lead to new submarine navigation, ground-penetrating geological sensors, and aerial ...
