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 ...

We tend to think of gravity as being about as constant as it gets. It is the invisible anchor that keeps our feet on the ...

While a "gravity hole" in Antarctica has been on scientists’ radar for some time, its history has never been fully understood. New research is beginning to change that, and in doing so, suggest ...

A scene from the movie Gravity. In real life, gravity is always bringing us down—particularly scientists who attempt to measure gravitational force. Try as they might, physicists cannot agree on a ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

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 ...

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 ...

Through extremely high precision measurements of a pulsar orbiting a white dwarf star, astronomers have found that the gravitational constant, which dictates the force of gravity, is "reassuringly ...
