Quantitative Research on the Critical Dissociation Energy of Substantial Matter and Equivalent Radiation Temperature of High-Energy Gamma Photons

Experimental data from RHIC, LHC heavy-ion colliders and lattice QCD simulations yield a unified conclusion: the critical temperature for complete dissociation of all substantial matter is 2×10^12 K (2 trillion Kelvin), corresponding to an equivalent photon energy of 172.35 MeV. Mainstream black hole theories contain two irreconcilable contradictions. On one hand, high-energy physics experiments verify that once the equivalent energy of a system reaches 2 trillion Kelvin, all substantial matter will completely dissolve, leaving only pure photons without any material particles. On the other hand, the singularity theory of general relativity claims that the central singularity of black holes contains substantial particles with infinitely high real thermodynamic temperature. It also equates the equivalent radiation temperature converted from high-energy photons to the genuine thermal temperature inside singularities. Based on the critical threshold measured by public experiments, this paper completes quantitative conversions between energy and temperature, and compares the magnitude with the 1.4 PeV highest-energy gamma-ray photon observed by LHAASO in the universe. It clearly distinguishes two completely different physical concepts: real thermodynamic temperature and equivalent radiation temperature. Real thermodynamic temperature relies on random thermal motion of substantial particles and becomes completely invalid once the energy exceeds the dissociation critical threshold. Equivalent radiation temperature is merely a mathematical tool for quantifying photon energy; no matter how large its value is, it cannot prove the existence of substantial matter or real high temperature in the region. The claims of substantial particles inside singularities, infinite temperature at singularities, and Planck temperature are all mathematical fabrications derived from confusing the two temperature concepts. This paper fully falsifies the above erroneous viewpoints through quantitative calculations.
