Could a gold shell around a planet exist, suspended by a magnetic field (gold is diamagnetic), given the following constraints?
- A gold layer enveloping a planet, arbitrarily thin.
- Unspecified height, likely to be where atmosphere is less dense with fewer jumps of pressure.
- a strong magnetic field that repels the gold and keeps it suspended thanks to gold's diamagnetic properties exists or was created.
- No specific function has to be performed by the sphere, just aesthetics. Make the planet shiny as a gold ball.
- An alien race has sufficient energy reserves (e.g. huge uranium deposits) to avoid relying on solar panels. They prefer being shiny instead of using solar power.
- The sphere should not be built, it just needs to be kept suspended ( so I do not need to know how it was built, that's another problem, just need to know if it can be maintained)
