In the earlier article and video, we proposed that there was a layer of what we called “slush” – some kind of material which was not quite water, but was not ice. We also calculated the volume of water in the inner earth, based on the figures we had suggested then. Now, with the new/additional information about the proposed Ringwoodite layer, we can improve these calculations.


The discovery of Ringwoodite has given rise to some geological "flapdoodle". There are some interesting comments on Ringwoodite here:

There never was nothing.
