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 ...

In A Nutshell Antarctica, not the Indian Ocean, hosts Earth’s strongest nonhydrostatic geoid depression when scientists ...

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

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

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

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 ...

A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth’s ocean today. By applying a method of calculating gravity that was first developed for the moon to data ...

A frozen continent at the bottom of the world sits over the deepest dip in Earth’s gravitational pull, a feature that has persisted for roughly 70 million years. Scientists have long known about this ...

A mysterious gravity dip beneath Antarctica is growing stronger, shaped by deep Earth forces over millions of years.
