The universe is mostly void space with galaxies...
...and galaxies are mostly void space with solar systems...
...and solar systems are mostly void space with planets...
...and planets are materials of mostly void space with molecules...
...and molecules are mostly void space with atoms...
...and atoms are mostly void space with neutrons, protons, and electrons that we initially thought were solid...
