Scientists have puzzled over the origins of a gravity hole in the Indian Ocean for years. Now, researchers think the sunken floor of an extinct ocean could be the cause.

Researchers have created a map of oceanic “dead zones” that existed during the Pliocene epoch, when the Earth’s climate was two to three degrees warmer than it is now. The work could provide ...

A vast 'gravity hole' in the Indian Ocean, where sea levels dip significantly due to weaker gravity, has finally been explained. Scientists discovered that ancient remnants of the Tethys Ocean ...

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 ...

The Indian Ocean’s mysterious gravity hole may be the result of a prehistoric ocean erased by time A new study postulates there was an ancient ocean that no longer exists, given the planet's ...

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).

To understand why this ocean alone bears a country’s name, one must know about the interesting stories that are a combination of instances from ancient empires, colonial explorers, and post ...

Marine scientists have discovered an ancient shark graveyard in the Indian Ocean that includes teeth from an ancestor of the massive megalodon apex predator.

A vast expanse of the Indian Ocean is a staggering 100 meters lower than the global average sea level because of a major dip in Earth’s gravity. Scientists now think they know the cause ...
