Are there spaces in between air molecules? If yes what is in
those Not only is there empty space in between molecules, there
is empty space INSIDE molecules and atoms! This question is
actually a very old one - the greeks debated "atomism", with the
objection to "atoms" being that if you have atoms, then you must
have empty space between atoms, and this did not seem to make
sense. Well, it turns out to be true - space has a structure all
by itself, and atoms and molecules just move around in it. Of
course, there are electromagnetic fields and other similar
things that penetrate space everywhere, so even empty space is
not really quite empty. So maybe both sides were right. Click
