Introduction: The exploration of the stress-free evolution of the universe has previously focused on dark matter and ordinary matter. This paper extends the investigation to antimatter, revealing its response to gravity akin to ordinary matter.
Analysis: The exponential stress-free model is employed to demonstrate that the production rates of particle matter and antimatter are equal, aligning with baryon symmetry. The observed ratio of particle matter mass to total mass under baryon symmetry is utilized to analyze the temporal dynamics of matter and antimatter expansion. Intriguingly, the study uncovers that the signal of antimatter precedes ordinary matter by approximately 2/3 of the time constant for antimatter annihilation. Furthermore, the annihilation process is identified as the driving force behind the initial expansion rate of the universe.
Conclusions: The application of the exponential stress model, initially devised for wave-particle duality, extends to elucidate the relationship between particle mass and antimatter mass. The central prediction is the occurrence of baryon symmetry, challenging the misconception of baryon asymmetry by highlighting the vast difference in time scales. This incongruity provides a unique cosmic structure—an expansive, mass-rich universe on the large scale harmonizing with a mass-poor, small-scale universe. Despite the myriad papers on cosmic evolution, the concept of stress, familiar to fluid dynamicists, appears largely overlooked. This research contributes to the understanding of cosmic evolution, revealing a universe intricately balanced and free from the constraints of traditional stress dynamics.
