Bearing in mind the sun is a larger gas giant than Jupiter, one might reconsider the anomalies of Mercury against the assumed centre of the sun, with the baricentre of the sun in a field n-bodies, four of which are gas giants not including Earth or Venus
Then one has to consider the implications of Venus, Earth and perhaps Mars in the light of the Deep Hot Biosphere which first produced the theory of a liquid core to the earth. Professor Thomas Gold asserted the centre of Earth is a super-heated core with temperatures in excess of 800 degrees (I don’t remember if that is 800F or 800C) regardless 800 F is 426.6C at which temprature water is approaching red heat and easily capable of dissolving rock.
This would at least go some way to explain why most volcanoes are well within the sub tropics. Perhaps not so easily explain the location of most earthquakes is between 30 degrees north and 30 degrees south?
Or does it not? Hang on, if the inertia… umm. I need to think about that one… back soon, relatively speaking. No the inertia of super-fluids is well out of my abilities. Not beyond the holy spirit though. Perhaps a little longer, maybe?
