Source. Take a plane wave function, because we know its momentum perfectly. Apply a constant voltage to an electron. You can easily bring it beyond the speed of light at about 255.5 keV. Superconductor resistivity experiment video by Ciro Santilli 37 Updated 2025-05-23 +Created 1970-01-01

It is exactly what you'd expect from the name, Waring was watching Netflix with Goldbach, when they suddenly came up with this.
