Question:
Asking on behalf of the class teacher who brought students to the lab: "Why planets are spherical?


Replies:
Because things roll downhill.

You could think of a cube-shaped planet as a spherical planet with eight humongous mountains. Whenever there's any perturbation (e.g., an earth quake) stuff from the mountains is going to come down; only very rarely will things go up. This planet will become more spherical as it ages.
