The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.

When the gravitational pull is smaller, someone weighs less. The moon, however, does have inconsistencies in its gravitational field because of "Bouguer" gravity anomalies.

These larger top-of-the-line devices can detect changes to gravitational fields of around one part in a billion, whereas this one can do so to about one part in 60 million.

When a beam of light enters a powerful gravitational field like the sun’s, it departs from the straight trajectory and forms a curved path like a planetary prism — making it harder to spot.

The recent study, published in the peer-reviewed journal Physics Review Letters, suggests that the magnetospheres of Earth and Jupiter could be key in converting gravitational waves into ...

Because the bar is horizontal to the Earth’s gravitational field, Cavendish was able to remove much of the planetary force from the measurements. Cavendish used two small lead spheres two inches ...

On the night side of Earth, the sun’s gravitational pull on me will be additive to that of Earth, whereas on the light side it will be subtractive. So, do I weigh more at night? Mike Follows ...
