      Ah, there are lots of possible answers to this one, depending on what exactly you mean.

      Answer 1: Mostly empty space!

      Answer 2: Most of the matter in the universe is apparently dark matter (which we can’t detect)

      Answer 3: Atoms, all kinds of subatomic particles, and energy / radiation
