Energy

This note introduces three interlocking definitions in the σ := i.c.t (E = -i.c.p_t) language and derives a chain of consequences that reframe some of the deepest questions in physics. The central result is that temporal momentum p_t = imc for a particle at rest. This single equation says: rest mass is the magnitude of temporal momentum. Mass is not a mysterious intrinsic property — it is how much a particle "pushes through time." Inertia is temporal momentum. From this, energy E = mc² emerges a
