how did they measure the volume of that buried āoceanā?
At that depth the water infiltrated in the rocks must be boiling, because the geothermal gradient of the Earth is 25 Celsius /1 kilometer depth, meaning with every kilometer in depth, the temperature increases with 25 degrees Celsius.
That news about the āoceanā three times bigger than the whole known planetary oceans sounds like a 1st of April jokeā¦ As i know, Agartha is in the etheric plane, not in the physical plane.
" The temperature of the mantle varies greatly, from 1000Ā° Celsius (1832Ā° Fahrenheit) near its boundary with the crust, to 3700Ā° Celsius (6692Ā° Fahrenheit) near its boundary with the core . In the mantle, heat and pressure generally increase with depth."
