Electron-proton structure is already conclusive. It is pretty stupid to rethink about it. But there are always some things in my mind which I can’t get rid of, so I can’t help thinking about it for decades, you guys must understand that is really painful. I rather metaphorize proton and electron into male and female, more than into (+) and (-). Because in natural fact, there is no negative, and the proton meets the electron will not disappear, so they shall not mark as mathematics symbols. They attract each other as male and female. Now comes up the questions, how about they are not equal, like protons have more energy, or electrons do. How about they haven’t got the notes from god, that they only can pair one another. After all, electrons equal protons and they match one on one, that is a hypothesis we put on them, but is that the fact? Let’s do some hypotheses without this one.
