Definition and Significance of Wave-Energy

Standard physics uses energy E as the fundamental physical quantity for describing particle states, with dimensions kg⋅m2/s2. However, the energy reading is an average value on a projection layer — it cannot distinguish between particles with the same energy but different wavelengths. This paper proposes a new physical quantity — Wave-Energy — denoted by the capital letter SS, defined as the product of a particle's total energy E and its macro-rotational wavelength λ: S=E⋅λ Its dimensions are kg⋅m3/s2. Wave-Energy reflects the complete state identifier of a particle on the current projection layer, rather than a single energy reading. It is the key quantity for distinguishing different particle states, and one of the core invariants within the World Quantum Theory (WQT) projection framework.
