Answer:
Actually, most things are not made up of atoms. Aside from the obvious (atoms themselves, their components and their components' relatives), the particles that mediate the fundamental forces (gravitons, photons, gluons, and W and Z bosons, though to be fair only the last two have any actual mass), dark matter, and dark energy are not made up of atoms. Light, an electromagnetic radiation, is not made of atoms. The plasma in stars is not technically made of atoms because electrons and nuclei are not combined into atoms. In fact, since dark energy is theorized to make up some 3/4 of the universe and we're fairly certain that there's more dark matter than there is of the more familiar sort, it's possible - even likely - that atomic matter comprises less than 10% of the universe. So yeah, most of the universe is made up of non-atoms.
hope this helps:)
