I think that once you start getting philosophical and asking what "open 
space" is, this starts to become nonsensical.

Sure, if you measure the space taken up by the nucleus compared to the space 
taken up by the whole atom, there's a lot of "open space" there. But that 
"open space" is full of electrons and photons, which is why it doesn't all 
collapse. If it were really "open" then it would all crunch down together 
under its own attraction. The fact that it's actually full of electrons is 
what's holding the atoms apart.

   Forget "focus follows mouse." When do
   I get "focus follows gaze"?
