No, mountain no have big hole. Mountain very big and very hard. But atom very tiny and sometimes it can go through the mountain without breaking it, like a ghost or a shadow. This happen because atom is not only a tiny particle, but also a wave. And when atom wave spread out, it can sometimes sneak through the mountain, even though it looks impossible. It like when you throw a rock into water and the ripples go around a big rock, but sometimes they go through a small gap in the rock. Same thing with atom and mountain!
