Consider an isolated Borg cube of uniform density ﬂoating somewhere in the Neutral Zone. Find the ratio of the gravitational potential energy of an atom at the center of the cube (arising from the rest of the mass in the cube) vs. the gravitational potential energy of an atom at the corner of the cube (i.e. U corner / U center ). Take the gravitational potential energy at the edge of the universe (i.e. inﬁnitely far away from the cube) to be zero ( U ( ∞ ) = 0). Hint : There is an easy way of doing this problem that involves breaking the cube into smaller cubes!...
