In the realm of science, jaw-dropping discoveries seem to be arising with increasing frequency, captivating our imaginations with their profound implications. In recent times alone, we've been astounded by the revelation of a menacing black hole directly aimed at our planet, the unearthing of a colossal hole in the sun, and the rediscovery of a continent that had been absent from our maps for a staggering 375 years. And now, we are only just grasping the extent of a vast ocean concealed beneath the Earth's crust.
Deep within the Earth, approximately 400 miles beneath our feet, lies an immense reservoir of water locked within a unique type of rock called 'ringwoodite'. Scientists had previously uncovered the existence of water stored in the sponge-like structure of mantle rock, existing as a fourth state distinct from the traditional forms of liquid, solid, or gas. This groundbreaking finding was presented in the 2014 scientific publication entitled 'Dehydration melting at the top of the lower mantle'.
