Recently, groundbreaking scientific discoveries have been rolling out at a breathtaking pace, from astronomical research on what's inside a black hole, to the majestic 8th continent and the North American lake larger than the Great Lakes combined.

Each one of these findings seemed incomprehensible until now. Yet, perhaps the most awe-inspiring is this: deep beneath our feet, below the Earth's crust, lies a colossal ocean.

At an astonishing depth of approximately 400 miles beneath our planet's surface, there is an abundant reservoir of water stored within a rock type identified as 'ringwoodite'. This intriguing revelation is reshaping our understanding of the Earth's water cycle and its intricate geophysical processes.
