They had the typical appearance of spherical or elliptical aggregates of altered erythrocytes surrounded by an envelope.
It is a mathematical truism that a spherical surface cannot be developed into a plane.

The elliptical shape can curve, but a round spherical shape can not.
For example, he held that fire rises in order to reach its natural place, a spherical shell just inside the orbit of the moon.
This exotic matter forms a thin spherical shell and has negative mass and positive surface pressure.
Kepler showed that the distances of the planets can be correlated with the radii of spherical shells, which are inscribed within, and circumscribed around, a nest of the five regular solids.
