OK, cool now teach your family that calls their web browser “The internet” enough computer science to adequately understand and audit this proposed open system and convince themselves that their votes are counted in a fair, verifiable and secret manner. Also that the implementation does not have obvious side channels and what is actually running is built from the published source code.
Like, If I was part of some shady powerful elite I’d love a fully automated setup. Most people will not be able to check the system deeper than “phone displays green check mark” without an unreasonable time investment.
On the other hand, “room full of people opens box full of papers and counts them while verifying each other” is intuitive enough for almost anyone to grasp and gain confidence in.
No, it either does proton-proton collisions or heavy ions, both regular matter. At TeV energies the added energy from anihalating matter with antimatter isn’t that much of a contribution anymore that it would justify the added complexity.
Its predecessor collided positrons with electrons though. But the LEP was more for precise refinement of known interactions and not so much about reaching the highest possible energies.
