what's the empty space between the atoms made of?

  Nothing (or a probabilistic electron cloud? I don’t think it counts as “being made of” something in a meaningful way)

    1) The old answer was some kind of ether. 2) The new answer is some kind of quantum field, with particles popping into and out of existence spontaneously.

  when you’re at that scale you need to have a good idea of what you mean by “made of” before you can get an answer. You end up trying to figure out what it means for a space to be occupied or unoccupied and coming to the conclusion that space is either 100% occupied or 0% occupied but not really anything in between which isn’t just an arbitrary threshold
