Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more ...
After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...
The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...
Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...
Earth, in most renderings, is a smooth sphere with a glossy complexion—a blue marble, as pictures snapped from space have shown us. Earth scientists know that’s not exactly true. Earth, in fact, is an ...
A mysterious gravity dip beneath Antarctica is growing stronger, shaped by deep Earth forces over millions of years.
