Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

Researchers uncover how slow changes deep inside Earth created Antarctica’s gravity anomaly and may even connect to ancient ...

A region beneath Antarctica where Earth’s gravitational pull is measurably weaker than anywhere else on the planet has persisted for roughly 70 million years, according to new research that traces the ...

A vast “gravity hole” beneath Antarctica became stronger as the continent shifted into an ice-dominated world tens of ...

The simulations showed that the gravity hole was initially much less pronounced. Between roughly 50 million and 30 million years ago, however, it intensified significantly. This period coincides with ...

[ADDENDUM 11/26/12: It has been pointed out to me that two planets that have the same surface gravity won't necessarily have the same escape velocity, which appears to undermine my argument that it ...

NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission has uncovered the origin of massive invisible regions that make the moon’s gravity uneven, a phenomenon that affects the operations of ...
