Vast Subterranean Ocean Holds More Water Than Earth's Surface

Scientists have discovered a massive ocean hidden beneath the Earth's crust, stored in a rock called ringwoodite. This water, three times more than what is found in the oceans on the surface, is in a sponge-like state within the rock. The findings suggest the existence of a whole-Earth water cycle and may help explain the abundance of liquid water on the planet's surface. This discovery adds to a series of recent scientific revelations, including the identification of a black hole pointing towards Earth and the uncovering of a missing continent after 375 years.
