- Sure. I agree 100%. Even without the exclusion principle, EM repulsion
- would keep your chair leg from passing through the floor - but chemistry
- would be so different that trees would not likely exist from which to
- make the table.
-
- The exclusion principle comes into play, in the collapse of massive
- stars, for example, only at the point where EM is neutralized by inverse
- beta-decay driven by the massive pressure. Then only neutrons are left,
- at least in the core, supported only by the degeneracy pressure. Before
- that point, it is the electromagnetic repulsion of protons and electrons
- which is responsible for the size of stars and their tendency not to
- collapse when cold.
