Gravity feels steady. You drop a set of keys, and they fall the same way every time. That reliability makes it tempting to picture Earth’s pull as uniform. It is not. After accounting for Earth’s ...

A huge, mysterious so-called “gravity hole” under the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study. Researchers recently offered the possible ...

Researchers think they’ve found the reason for the most significant drop in Earth’s gravity, known as the Indian Ocean geoid low. In this location in the Indian Ocean south of Sri Lanka, our planet’s ...

A recent study published in Geophysical Research Letters has uncovered new insights into one of Earth’s most puzzling anomalies—a massive gravity hole beneath the Indian Ocean. The phenomenon, known ...

MEASURING Earth’s hidden structures could soon be as simple as looking at your watch – provided it’s a super-accurate atomic clock. Such clocks are nearly good enough to deliver a detailed geoid, says ...

Antarctica has a surprising peculiarity: a gravitational anomaly, an area where gravity is weaker than the average on our planet. It is not a hole in the ground. The force of gravity naturally changes ...
