Chasing Ghosts of the Universe

You probably heard that matter is pretty much an empty space. It's true. Everything is made of tiny particles with nucleus in their centers and cloud of electrons orbiting around. If we take Hydrogen (H) for example - the smallest atom with just one proton in nucleus orbiting by just one electron and if we scale the proton to be the basketball size, the orbit of the electron in diameter would be something about 15km. Both, nucleus and electrons are electromagnetically charged, keeping everything in stable equilibrium and also inside nucleus two more fundamental forces - strong and week nuclear interactions are keeping all the matter and energy in line. However, the smallest atom in the Universe is not the smallest, standalone system we know of. According to standard model, all atoms and complex molecules found in nature or artificially produced are made of fundamental particles. Something we cannot cut into smaller pieces. Electron is one of them. But there are more. So far, as far
