Physicists have used the quantum nature of matter to obtain a highly precise value for the universal gravitational constant, the 'big G' that appears in Isaac Newton's law of how gravity pulls ...

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 ...

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 ...

Newton's law of universal gravitation, which describes the attractive force between two masses separated by the distance, is one of the greatest achievements in the 17th century. The strength of this ...

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 ...
