“The Pauli Exclusion Principle doesn’t only explain why matter is solid, but also why it occupies the amount of space that it does. Again: it isn’t just the uncertainty principle and electrostatic repulsion that’s responsible for volume; if matter were made of bosons, it wouldn’t occupy space in the same fashion that it does when it’s made of fermions”
