On the Essence of Force: Causal Inversion in the Existing Messenger-Particle Model

Modern particle physics widely adopts the messengerparticle interpretation of fundamental interactions. It postulates that the strong force is mediated by gluons, the electromagnetic force by photons, and hypothesizes the existence of gravitons for gravitation. Decades of intensive theoretical and experimental efforts worldwide have failed to identify gravitons or construct a consistent physical description for them. While this paradigm yields mathematically acceptable fits to experimental data, it reverses the underlying causal relationship between matter and force. Force is not an independent entity. It represents an instantaneous action-at-a-distance tendency among matter and energy, requiring no messenger particle for transmission. Matter is fundamental; force is a secondary phenomenon derived from material structures. The weak interaction is not an intrinsic fundamental force of the universe. It arises as a composite effect from the superposition and coupling of the strong and electromagnetic forces under the extreme microscopic conditions inside atomic nuclei. At the origin of the universe there existed only pure energy. Light constitutes the primordial manifestation of energy. Photons can gain or lose energy, spanning the full spectrum from visible light to gamma-ray photons. Low-energy photons cannot achieve force-locking and thus cannot form matter. Only gamma-ray photons, after sufficient energy elevation, can trigger the force-locking effect at high-density aggregation, whereby free light energy becomes bound and condensed into matter. Experimental evidence from high-energy electron-positron pair production and electron-positron annihilation directly demonstrates that force emerges together with matter and vanishes when matter decays. This paper examines inherent defects in the messenger-particle paradigm from four perspectives: cosmic origin, photon energy-level evolution, experimental evidence, and theoretical consistency.
