      As far as I know, this is still the subject of ongoing research. We know that we are made of atoms, as are the planets and the stars, but there is also a hypothetical form of matter called “dark matter” that is supposed to make up a huge percentage of the universe. I think the existence of dark matter is still a somewhat controversial thing, however.

      I think the honest answer here is that I don’t know, but this would be a very good question to ask a physicist.
