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 ...

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

A peer-reviewed study published in Scientific Reports has reconstructed the evolution of the Antarctic Geoid Low, the strongest negative gravity anomaly on Earth, over approximately 70 million years, ...

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...

Did you know that gravity isn't the same everywhere on Earth? In Canada's Hudson Bay, gravity is slightly weaker than the global average—an anomaly scientists have been studying since the 1960s. As ...

South of Sri Lanka, the Indian Ocean is home to the planet's lowest gravity anomaly, a large and subtle depression in the gravitational field. Despite the seemingly calm ocean surface, the region's ...
