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 ...

We tend to think of gravity as being about as constant as it gets. It is the invisible anchor that keeps our feet on the ...

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 ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million ...

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

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 ...

“Quantum sensing opens an entirely new domain for U.S. space leadership,” said Dana Anderson, Chief Science Officer at Infleqtion. “By deploying this technology in orbit, we are demonstrating the ...

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

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 ...

The Earth is a dynamic system constantly undergoing change. As the processes of change affect the Earth's topography—the heights of land, ice, and ocean surfaces—they also modify the distribution of ...
