The Nature of the Divergence Between Quantum Physics and Classical Physics——The Root of the Split Between Two Theories as Seen Through Frequency Layer Misalignment and the Leap

The divergence between quantum physics and classical physics is widely regarded as the most profound unresolved puzzle in physics. This paper, from the perspectives of World Quantum Theory (WQT) and Frequency World Theory (FWT), points out that the root of this divergence is not that "the microscopic world defies reason," but rather two fundamental cognitive errors: frequency layer misalignment and cross-layer leap. The parameters of classical physics (G, g, Earth's mass, etc.) are self-referential readings measured in the Earth's macroscopic frequency layer. The parameters of quantum physics (h, m_e, α, etc.) are self-referential readings measured in the electron frequency layer. They belong to different frequency layers, each self-consistent internally, but not directly interchangeable. However, standard physics treats the parameters measured in the Earth layer as "universal constants of the cosmos" and applies them to the microscopic layer without frequency-layer conversion — this is a cross-layer leap. This leap creates an unbridgeable gap between the macroscopic and microscopic. The divergence between quantum physics and classical physics is not a difference in physical laws, but two readings of the same underlying structure in different frequency layers, mistakenly treated as two different "theories."
