Energy–Matter Conversion and the Role of Black Holes in Shaping Physics of the Cosmos
ORAL
Abstract
Understanding the origin of elements remains a central challenge in cosmology. This study extends nucleosynthesis modeling in the early universe using the Geant4 High Energy physics simulation toolkit, to explore nuclear reactions underlying Black Hole Nucleosynthesis.
The analysis explores reaction thresholds, initiation temperatures, and Q-values to trace the formation of nuclei up to Z≈238. Results reveal a linear rise in initiation temperature up to Z=108, followed by exponential growth explain the observed elemental cutoff near Z=118. Most synthesis reactions display negative Q-values, indicating energy-absorbing behavior that may explain the thermodynamic nature of black holes and their role in element generation. The model further suggests that relativistic jets from quasars could carry observable signatures of newly formed nuclei.
The study discusses an extended version of special relativity with Q-value to explain physics of the cosmos. Energy-to-matter conversion is shown to drive universal expansion, while matter-to-energy conversion contributes to compression, linking Q-values with cosmological dynamics. Stars act as fusion-driven energy sources (positive Q reactions) producing compression, whereas black holes operate as synthesis reactors (negative Q reactions) producing expansion. These mechanisms provide a unified thermodynamic interpretation of cosmic evolution through Inflation (clearly explain), Expansion, Steady State, Compression, and Collapse phases.
