According to recent developments, scientists have discovered a reservoir of water deep beneath Earth's surface that is three times the size of Earth's oceans. According to sources, Northwestern University in Evanston, Illinois, discovered this subterranean water reserve, which is located roughly 700 kilometres beneath us.

In their effort to find the source of Earth's water, researchers uncovered a revolutionary discovery: a gigantic ocean hidden deep under the Earth's mantle, far below the surface. This hidden ocean, contained within ringwoodite, a blue-colored rock, challenges our concept of where Earth's water originates.

The extent of this hidden sea calls into question Earth's water cycle, implying a potential shift away from theories that place comet impacts as the primary source. Instead, the idea that Earth's seas may have slowly seeped from its core gains traction.

With this significant discovery in hand, researchers are keen to collect further seismic data around the world to determine the prevalence of mantle melting. Their results have the potential to transform our understanding of the Earth's water cycle, providing new insights into one of the planet's most fundamental processes.
