# Back Cover **The Physics of Energy Flow** presents a monistic derivation of physics from continuous electromagnetic energy transport. Instead of assigning independent ontologies to matter, charge, force, gravity, and curved spacetime, this book starts from one substrate only and asks what must follow if energy exists, flows, closes, and organizes. The result is a reconstruction in which Maxwell dynamics is the minimal local closure of transport, quantization begins as topological closure, mass is trapped energy, force is bookkeeping for momentum transfer, and gravity is refraction. This is not a denial of mathematics. It is a refusal to mistake mathematical maps for the territory they describe.
