PHYSICAL ENERGY EXCHANGE AS AN ADMISSIBILITY CONDITION IN PHYSICS

This paper isolates physical energy exchange as a candidate admissibility condition for physical reality and evaluates it under a strict elimination-by-necessity framework. Energy exchange is examined solely as a physically enforcing mechanism acting through interaction in spacetime, independent of mathematical bookkeeping, conservation descriptions, or interpretive constructs. By removing non-enforcing representations while retaining all physically enforcing interactions, the analysis determines whether energy exchange is necessary and whether it is sufficient for physical reality. The paper shows that energy exchange enforces physical change but cannot operate independently of force and momentum exchange, establishing energy exchange as necessary but not sufficient within a closed, mechanism-only logical structure.
