Massimo Tori says, could you clarify why Calabi-Yau manifolds are the preferred choice in superstring theory for describing the six compactified extra dimensions? What specific properties make them so suitable for this role? I'm not the superstring theory expert to answer this question, but this is, I think, a pretty basic one. The basic idea is just that they solve Einstein's equation.
