To make it clear, it has to be really strong, stronger than diamond for example. Graphene wouldn't do the trick either. https://en.wikipedia.org/wiki/Vacuum_air

- fnj 9y agoIt's not just the strength that is lacking. The thin shell would buckle long, long before the compressive strength limit was reached. We are talking orders of magnitude.
- phreeza 9y agoYea, the numbers in the linked article are based on Zoelli's formula for the critical buckling pressure of a sphere.
