Feynman_s Simple Idea That Explains Why Space Is So Hard

Richard Feynman's famous diagrams drew particles interacting through space, not fields. He used this simple picture to remove the "infinite energy" problem that quantum fields create in a vacuum . But gravity ruined the trick—it responds to all forms of energy, so the vacuum's hidden activity still breaks the equations. The idea almost worked, but space refuses to be that simple. A quiet reminder that nature always has the final say.
