I need a nuclear lab to conduct one of my experiments. Can you deliver? It's not that complicated but it needs some special equipment though. Positive result guarantees our spot under Sun :-)
@Ulrich Yes, that's true in contemporary physics. But if you look at things through my theory (ToEbi) you'll realize why charge won't be conserved in this case.
are you aware that for photons it is quite trivial to experiment with colliding beams with opposite spin direction. Photons show not the least tendency to interact at all in this case. Replacing your protons by electrons would shrink size and price of the required equipment considerably.
Then you better contact a manufacturer of electron microscopes. For them it would probably be a minor project in their R&D department to build such a thing in desktop size. However, these guys know their electrons and you are in danger that they will react with LOL.
