The biggest ocean on earth has just been found! An international team of researchers have found a gigantic ocean near the Earth’s core that is 3 times bigger than all of the world's oceans. The water reservoir is discovered in the boundary between the Earth's upper and lower mantles.
The team of scientists from the Institute for Geosciences at Goethe University in Frankfurt, Germany has said that this new research will provide empirical evidence for an amazing long-held hypothesis - water from the oceans travels by subducting slabs into the transition zone.
And since the inside of the Earth is also part of the water cycle, the water cycle is speculated to extend across the whole globe.

If it's near the core I wonder how hot that water is?

And what would fill the void left behind once this water migrated up?

I have never heard a plausible explanation as to where all the planet's water came from.
Not buying comets.
Anyone help me out?
I really don't know.

The Earth is a dynamic planet. It is made of layers: the crust, the mantle and the core. The mantle itself is an interesting zone, with differences between the upper and lower mantle. It helps to learn the upper mantle and lower mantle definition, along with their differencing characteristics, to greater understand the Earth’s geological behavior.
The first difference between the upper mantle and lower mantle is their location. The upper mantle adjoins the crust to form the lithosphere, whereas the lower mantle never comes in contact with the crust. In fact, the upper mantle has been found to contain tears in certain areas, such as the Indian tectonic plate, whose collision with the Asian tectonic plate has caused many devastating earthquakes. These rips occur in multiple places in the upper mantle. The areas of crust above these tears are exposed to more of the mantle’s heat than other areas, and in those areas of warmer crust, the earthquakes are not as prevalent. The evidence from the research suggests that the crust and upper mantle in southern Tibet are strongly coupled. Information such as this can help with earthquake risk assessment.
