Grid-System of our world

Atoms are really small. Dur, and within those really small atoms are even smaller particles, neutrons, electrons, and protons. Compared to each other and the size of an atom, the atom itself is about the size of Hawaii, where a neutron/proton is the size of a house, and an electron is the size of a grain of sand. So overall the atom consists of mostly empty space. When the atoms collide into each other, why don’t they just go thru each other? This can be answer by a nuculear gridsystem, in which all the particles are aranged onto a grid, where nothing can travel in between the points on that system. This also explains why light doesn’t go thru solid matter. Now, the particles are different sizes than each other, neutron/proton being roughly 1800 times more massive than an electron. I can’t really explain that, but you’ll just have to trust me, it’s all relative, and all particles, when they are that small, look the same.
