Earth's Core
This topic opens with a link to a report on study of the Earth's core.
https://www.cnn.com/2025/02/10/science/ … 9227532606
The article covers quite a bit of the subject.
Apparently the solid core is turning more slowly than the Earth as a whole, which is a change.
Geoscientists have been studying earthquake waves to discover that the solid core's surface is changing shape as it interacts with the liquid layer above.

It may be a while before we see any posts to this topic. It appears that we won't have to worry about the core expanding for a few million years.

Re: Earth's Core
I thought I would put this here, as at one time the Earth likely was like this.
https://www.msn.com/en-us/news/technolo … 69fe&ei=11
So, if I understand a sub-disk of material would surround a planet which I think would protect it from the solar wind. My expectations are that water would be included into the planet, not just dust. In fact, it may be that the dust would generate water from the solar wind and then fall to the forming planet.
And it appears that our core has a lot of Helium 3 in it: https://physics.aps.org/articles/v11/133
Quote:
Now researchers predict the existence of a helium-bearing compound, FeO2He
, that could serve to store this enigmatic element. Their calculations indicate that the compound is stable at temperatures and pressures consistent with those found at the bottom of the Earth’s mantle—the mostly-solid layer between the crust and the molten outer core. If verified, the results would support the science behind using helium to trace the age and history of cosmological bodies, since other similar planets should contain the same material.
And so, I expect that the Earth did not require so much water to come in later from Comets or Asteroids.
And I expect that it may be possible that our Moon retained some things like Hydrogen and maybe Helium. Not sure of that.
But if it formed from a splash of the liquid mantle, very quickly or a ring of dust slowly, in either case the splash, might retain the existing Hydrogen and Helium, if any and the dust might accumulate water from the solar wind.
