Just when we thought we knew Earth... scientists found an entire ocean hiding beneath our feet.
Deep below the surface... about 400 miles down... researchers discovered a massive water reservoir trapped inside a blue mineral called ringwoodite. It’s not a liquid ocean like the ones we know, but it holds three times more water than all our surface oceans combined. That’s mind-blowing.
This discovery changes everything we thought we knew about Earth’s water cycle. It means water doesn’t just move above ground... it circulates deep within the planet, possibly shaping earthquakes, volcanoes, and even the balance of life itself. Imagine... an ocean we’ll never see, silently flowing in the planet’s heart.
It’s wild to think our own world still has secrets like this waiting to be uncovered. What other mysteries do you think are still hiding inside Earth?
