When you get down into the microcosm, atoms and molecules act a bit like solar systems... electrons revolving around a central nucleus. When you go to the macrocosm, you find star systems acting like atoms and molecules... planets revolving around stars.
That really is coincidently amazing; the similarities of the microcosm vs the macrocosm.
Electrons, neutrons and protons can produce sphere-like formations, but the Earth is flat though !
