How detailed could we make a sculpture of the earth the size of a soccer ball? Say we had a couple of decades to make a sculpture, how detailed could we make a sculpture of the earth the size of a soccer ball?
Is it technologically possible to create human sculptures in proportion to our scaled earth such that can be seen using microscopes as we see humans from satellites in space?
If not, what could we see?
And if humans cannot be made, how big should we make the earth?
You could only strive to make as smooth a ball as possible. Maybe just paint it.
The tallest mountain on that scale will be 0.11 [m radius of the soccer ball] / 6371000 [m mean radius of the Earth] * 8848 [m Everest height] ≈ 0.15 mm. A thickness of a sheet of good paper.
