Ken Wheeler has spent a decade arguing that physics took a wrong turn in 1905 — that there are no particles, no photons, no gravity as we know it; only one invisible medium, and two shapes it makes. This document reconstructs his entire worldview so you can understand it, explain it at dinner, and judge for yourself which parts are vocabulary and which parts are physics.
Every load-bearing concept, compressed to the sentence you'd actually say to another human. This is the whole worldview in two minutes.
