Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

Zone of divergence: A section through the centre of mass, O, of a planet and the single point, S, on the surface of the planet that touches its Brillouin sphere. The point O is the centre of the ...

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

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 ...

A region beneath Antarctica where Earth’s gravitational pull is measurably weaker than anywhere else on the planet has persisted for roughly 70 million years, according to new research that traces the ...

Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...

A new model of the Universe suggests that modifying Newton's theory of gravity could do away with the need for dark matter. The model instead relies on an as-of-yet undiscovered form of gravity to ...

HOW do you reconcile the two pillars of modern physics: quantum theory and gravity? One or both will have to give way. A new approach says gravity could emerge from random fluctuations at the quantum ...

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