This is a bit of a wild story, so prepare thyself.

It turns out the scientists have discovered that there is more water underneath the surface than is on top of it! But wait, there's more…

This water supply is around 400 miles underground stored in rock known as 'ringwoodite'. And it turns out that scientists think ringwoodite is mantle rock in a sponge-like state, which isn’t a liquid, solid or a gas, but instead a fourth state. 🤯

Oh, and did I mention that this was actually discovered back in 2014 (yeah, a full decade ago) and is only now making the news?!?

"The ringwoodite is like a sponge, soaking up water, there is something very special about the crystal structure of ringwoodite that allows it to attract hydrogen and trap water," said geophysicist Steve Jacobsen at the time.

"This mineral can contain a lot of water under conditions of the deep mantle,” added Jacobsen, who was part of the team behind the discovery.

If the rock contained just 1 per cent water, it would mean that there is three times more water under the surface of the Earth than there is in the oceans on the surface.

Whoa!
