Part 6/10:
As one imagines mega-structures, consideration is essential regarding their size limits. The larger a planet grows, the inevitable challenges arise from gravitational forces, altering rotational dynamics and atmospheric conditions. With the intrinsic limitations on rotation rates to produce a 24-hour day, the centrifugal forces become increasingly unfavorable, often necessitating a non-spherical design.
For instance, the structural design may favor a more elliptical arrangement to balance gravitational forces across its surface effectively, minimizing risks associated with intense centrifugal pulls at the equator.
