In response, the Casimir effect exists and applies in all cases when bodies, including particles, are present and at close distances. I did not misappropriate it. The Casimir effect between two plates is the Casimir effect between electrons on the surface of the plates. (Note that the solidity of matter is due to the electron degeneracy pressure between those electrons as established by Freeman Dyson)
The equation I used does account for 3 dimensions, but it does not account for all the Casimir forces, which is why I did not get 100x. (Note that I have been trying to work on or find a better equation to use in a follow-up paper.) My friend who successfully computed the binding energy for the deuteron also did so for tritium and and helium, so your argument that the Casimir effect does not apply for more than two bodies at once is nonsense.
You calculated the Coulomb force using the wrong distance. The table uses the distance between the outer radii of the protons, not the distance between the center of the protons, which is how you compute the Coulomb force.
As for the two proton problem, It is unstable because protons make quantum jumps an uncountable number of times each second, so they tend to jump away from each other so fast that we can never see them together in a metastable state under normal conditions. Degeneracy pressure and the force behind Pauli's Exclusion Principle are not speculative forces. Two protons, two neutrons, or a proton and neutron can never occupy the same point in space. As for quantum jumps, you can also consider that the neutrons in the nucleus actually do decay but the temporarily free electron is usually immediately recaptured by another proton converting it to a neutron, so there is continuous electron exchange going on. Contrary to mainstream physics there is no binding energy associated with this particle exchange. The binding energy come from the Casimir effect.
It is amazing to consider that every particle in our body is being replaced trillions of times each second.
