They'll fit together in pairs, like Lego's, in multitude. We'll have them range from simple too complex. From electrons, protons, neutrons, photons We'll create an imaginary Universe. Particles with mass and charge and spin will form as atoms, to number one hundred, a nice round whole number, or slightly more. And thus the Periodic Table was formed as a plan for the Particles to follow, which they did.
Force is information within each particle, what each is supposed to do.
Don't ask what information is, a term from the Institute of Mathematics. You can take my word for it. We'll decree that for their masses the Particles will attract. Gravity, mass, charge, spin, electrons, protons, photons, neutrons, not in our vocabulary. Every trade must have its tricks.
