Okay, im new so if what im talking about makes no sense, be easy...i dont really know if it belongs in classical physics? but here goes: Everything is made up of something smaller than itself, right? Say a table...its made up of wood, wood is made up of numerous compounds, which are composed of elements. These elements have atoms with nucleuses, protons and neutrons...and the neutrons and protons are most likely made up of something smaller..and on and on. But at the end, there must be a particle which is not composed of anything else..what im trying to get at is eventually something must be composed out of nothing. And if that is true...why when we hit a table don't we go through it? Okay please explain this to me and feel free to correct me!
