Do not think about "little balls". It's a fundamentally broken mental image that everyone was taught in high school chemistry. Already at atomic level things are adequedly expressed only as wave functions. Matter is not little balls made up of even tinier balls, but something altogether stranger - recall that matter and energy are interchangeable. I like to imagine the subatomic particles (like neutrons and protons) as beautiful rays of energy only temporarily trapped in particle form as ugly matter.
