A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects from floating skyward. For humans, it’s a leash that stops us from ...

Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. Here’s what happened.

Learn how Antarctica’s gravity hole formed inside Earth and grew stronger as its ice sheets took hold.

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 ...

A shifting of Earth’s poles, referred to as ‘True Polar Wander,” combined with the sinking of tectonic plates during the Cenozoic Era, altered the planet’s interior, with rising hot mantle material ...

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

Gravity seems constant but it turns out, Earth is weirder than that. Gravity actually wobbles a bit across the planet. And ...

Despite the dramatic name, these alignments aren’t exceptionally rare. The last six-planet parade occurred in January 2025, ...

According to a new study, researchers have identified a massive gravity hole-technically known as a Geoid Low-beneath the ...
