Scientists have theorized for years that a massive ocean, perhaps three times as large as any body of water on earth, lies 'neath our feet. Well, now they think they've found proof that such a sea can be found...some 400 miles down.

According to the science and technology website extremetech.com,

"This new study, authored by a range of geophysicists and scientists from across the US, leverages data from the USArray — an array of hundreds of seismographs located throughout the US that are constantly listening to movements in the Earth’s mantle and core. After listening for a few years, and carrying out lots of complex calculations, the researchers believe that they’ve found a huge reserve of water that’s located in thetransition zone between the upper and lower mantle — a region that occupies between 400 and 660 kilometers (250-410 miles) below our feet."
