If satellites can orbit the earth without anyone understanding the motion of the earth's gravity field to be the secret of unaided satellite propulsion and suspension, a rethink about why the atom splits and where the energy comes from would be okay. Giving consideration to a charge being an equal and opposite force system wouldn't hurt. The charge on one side of one proton gets annulled by the injected neutron and all protons lose their charge for an instant. Or something. A negative charge being a positive gravity field is probably worthy of thought.
