⚛️ Mostly Empty Space
Here's a mind-bending fact: atoms are 99.9999999999999% empty space! If a nucleus were the size of a marble in the centre of a football stadium, the electrons would be tiny specks orbiting in the outer stands. All the "solid" matter around you is almost entirely nothing. You can't fall through your chair because of electromagnetic repulsion between electrons, not because atoms are solid!
