The Indian Ocean has a mysterious million-square-mile 'gravity hole' where sea levels are 300ft lower – and scientists finally think they know what caused it ...

The new study makes the case that the massive dip, called the Indian Ocean geoid low (IOGL), is made up of slabs from the long lost Tethys Ocean that sunk within the planet.

Beneath the vast expanse of the Indian Ocean, a strange phenomenon has puzzled scientists for decades—a massive gravitational ...

Earth There's a gravity 'hole' in the Indian Ocean and now we may know why. Earth appears to have less mass beneath a certain part of the Indian Ocean compared with the rest of the planet.

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.

The Indian Ocean stretches from the southern tip of Africa to the Malacca Strait between Malaysia, Singapore and Indonesia; and from the Persian Gulf to far south-western Australia: over 80 ...
