There is a “gravity hole” in the Indian Ocean — a spot where Earth’s gravitational pull is weaker, its mass is lower than normal, and the sea level dips by over 328 feet (100 meters).

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.

Earth's geoid, a measure of its shape based on the study of anomalies in the gravitational field at its surface, has a big hole in the Indian Ocean. A team of researchers may have figured out why.

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

T he Indian Ocean "gravity hole" is the site of the deepest dent in Earth's gravitational field. It's a circular ocean region with a gravitational pull that's so weak, sea levels are 348 feet (106 ...
