The inner Earth seems to reflect the structure of the universe in 
logarithmic scale.

To me this seems quite astonishing, since that would indicate, that some 
sort or logarithmic relation to the outer universe must be present 
inside the Earth.

This is so, because without some kind of relation, the ratios between 
observable boundaries to the entire radius wouldn't be as similar as 
they are.
