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 ...

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

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 ...

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 ...

A new study has reconstructed the evolution of the planet’s strongest nonhydrostatic geoid depression —the Antarctic Geoid ...

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

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

Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...

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

Researchers found that shifting gravity patterns may have encouraged the growth of Antarctica’s huge ice sheets ...

The Earth is a dynamic system—it has a fluid, mobile atmosphere and oceans, a continually changing distribution of ice, snow, and groundwater, a fluid core undergoing hydromagnetic motion, a mantle ...
