I calculate that you'll need a structural material about twelve times as strong as, and one-quarter the density of, high-tensile steel for that structure to resist the tension generated by its own rotation. You could build it out of a polymer reinforced with carbon nanotubes. But not stone.

And that's not counting the 15km of stone as a passive load, that's leaving it out altogether. With 33,000 tones per square metre of load you'd need an 8-km-thick band of nanotube-reinforced polymer, or 1.5-1.7 km of flawless diamond or continuous nanotubes above and below to support the stone.

Decay is inherent in all composite things.
Nod head. Get treat.
