Two Questions about fundamental forces: 1. Gravity is attractive, Electromagnetics is attractive and repulsive, Strong nuclear is attractive only (?) ... Is the weak nuclear force repulsive only ? Wikipedia is _vague_ on this. Also, I'm remembering that gravity increase with the square of the distance, electromagnetics likewise, but strong and weak increase with higher exponents. Is this correct? 2. With E=Mc^2, it follows that mass is condensed photons. QUESTION: If there are binding (attractive) forces active over VERY small distances (following some inverse-Nth law), then the only 'particles' small enough to be bound together are photons. Is this an existing idea that has a popular name, is this obviously wrong for some reason, or is it a novel concept? I'm just some guy, I have no right to claim novel thought in this realm, it strikes me this has probably been thought of before.
