The Real Formation Mechanism of Jets from Supermassive Galactic Black Holes

The mainstream Blandford-Znajek (BZ) jet model, which attributes jet power to magnetic fields extracting black hole spin energy, contains fundamental physical paradoxes. Gamma-ray photons carry no electric charge or magnetic dipole moment, so strong magnetic fields cannot directly accelerate, constrain or drive pure photon flows. This contradicts astronomical observations that black hole jets consist solely of high-energy gamma photons near their black hole horizon origin, with solid matter only emerging at intermediate and far jet distances. Based on the universal physical framework that light is the fundamental origin of all matter, this paper proposes a tripartite jet formation mechanism combining spacetime compression from black hole angular momentum, collision and reflection blocking by dense accretion disk particle walls, and cumulative photon cluster pressure. This work definitively rejects the long-standing paradigm that magnetic fields supply the primary jet driving power. It coherently explains the origin, collimation and layered evolutionary properties of relativistic polar jets from supermassive black holes, resolving persistent inconsistencies between traditional theories and observational data.
