Scientists theorize that some exoplanets – worlds orbiting distant suns – might be water worlds, rocky planets completely covered by global oceans. This month, a researcher at Harvard University published new evidence that Earth itself was once a water world, with its own global ocean and very little, if any, visible land. Planetary scientist Junjie Dong at Harvard is lead author on the new paper, which focuses on the amount of water present in Earth’s mantle, the layer of rock between our planet’s crust and core.

Across the ages, sea levels have risen and fallen with temperatures but Earth’s total surface water was always assumed to be constant. Now, evidence is mounting that some 3 billion to 4 billion years ago, the planet’s oceans held nearly twice as much water enough to submerge today’s continents above the peak of Mount Everest. The flood could have primed the engine of plate tectonics and made it more difficult for life to start on land.
