The standard model assumes matter began as Venus came from the sea, complete and perfect, with charge an optional accessory, but that doesn’t explain charge neutrality. The earth is charge neutral, as is our galaxy, and the universe as a whole is probably the same, but why? Why are there as many electrons in the universe as there are protons? And why are there exactly twice as many down quarks as up quarks? If matter just began, why was charge doled out in equal positive and negative amounts? To say that the universe is charge neutral because it was made just so, is unsatisfactory.
Quantum theory tells us that events repeat at a fantastic rate, so any entity that isn’t 100% stable will re-configure, sooner or later. Every option is tried until one sticks, i.e. is stable. After the initial chaos, electrons, neutrinos, and quarks survived by being stable, and the first atom formed for the same reason, that a proton and an electron survive better together than apart. Other atoms then evolved in the same way, with an equal number of protons and electrons. The electrons around a nucleus shield it from neutrino strikes that could disrupt it, by turning a neutron into a proton, and the nucleus holds the electrons in orbit so they don’t fly off.
It follows that the universe is charge neutral because matter survived as charge-neutral atoms. Matter evolved rather than just began, so the universe is charge neutral by evolution, not because an initial design allocated it that way.
The standard model assumes matter just is but in this model, it evolved by the law of all action that whatever can happen eventually does, as the quantum world tries every option. Evolution, that the future is what survives, is then the second founding principle of our universe, but the standard model denies both these principles. Firstly, it opposed the randomness of quantum theory, seeking instead to impose its own fixed laws on matter. Secondly, it focused on transient particles, like the Higgs boson, that by evolution have no relevance. Physics needs a better model than one that is both anti-quantum theory and anti-evolution.
