Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the Universe, according to a decades-long study of a distant pulsar. This research helps to answer a ...

Astronomers have produced the best constraint ever of the gravitational constant measured outside of our Solar System. Gravity, one of the four fundamental forces of nature, appears reassuringly ...

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 ...

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.

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set ...

Throughout the universe, there are several underlying principles that we consider to be constants; for example, the speed of light in a vacuum. So many different aspects of our understanding of the ...
