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 ...

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 ...

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 ...

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

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million years ago. This corresponds to large-scale changes in the continent’s ...

F rom space, planet Earth looks like a perfect sphere. But it’s not. Obviously, the crust of the Earth is irregular, covered in jagged mountains and deep oceanic trenches, but even if it were ...
