SUMMARY
The discussion centers on the mathematical problem of determining whether a cube can be inscribed in a sphere with 10% of its surface area painted white and the remaining 90% black. The key argument presented is that if the diameter of the circle formed by the projection of the white-painted segment is less than the side length of the cube, then it is possible to inscribe the cube such that all its vertices are black. The method involves calculating the arc length corresponding to the white-painted area and deriving the angle at the center of the sphere to find the diameter of the projected circle.
