Forbidden vertex Memes

Emperor Palpatine's darkest secret isn't the Sith—it's Feynman diagrams. "Did you ever hear the tragedy of Figure 1.2 The Forbidden Vertex?" He's not talking about Darth Plagueis but electron-photon interactions with conservation laws that would make any physicist scream. That diagram shows a single electron emitting a photon and... turning into a positron? Pure scientific heresy! Conservation of charge weeps silently in the background. No wonder it's forbidden—nature would collapse faster than a grad student's will to live during finals week.
