The point is that the chaos principle of quantum physics states that in a nutshell the atom is made up of protons and netutrons and the distance between them is like the distance from one end of Westminster Catheedral to the other. In other words the amount of space contained in a whole atom is 99.99% recurring. Therefore mass itselff has an insignificant amount of actual solidity.
