gravitational analogue

The key idea behind hyperfine interactions is introduced first in a context that might be more familiar to you than the quantum world of nuclei and electrons: the world of gravitational interaction between massive objects. After this video, you will understand how the gravitational quadrupole moment of a mass distribution affects the gravitational energy of a system of masses. And you will understand the role and purpose of a multipole expansion.
