The sun is spherical because of hydrostatic equilibrium. Gravity pulls gas inward, while the energy generated by the sun's core pushes it outward. These forces balance out at a specific distance from the sun's center.
Since these forces are the same in all directions, the distance at which they balance is the same in all directions. This creates a sphere. The same principle goes for planets, just replace the force generated by fusion with pressure from the material that makes up the earth.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
