Z-Pinch Plasma Nucleosynthesis Under Variable Mass Conditions: A Conjecture on the Origin of Light Element Abundances

Standard Big Bang Nucleosynthesis predicts primordial light element abundances from a single parameter, the baryon-to-photon ratio. While successful for helium and deuterium, BBN predicts a lithium-7 abundance approximately three times the observed value — an unresolved empirical failure. BBN further assumes fixed fundamental constants throughout — fixed particle masses, fixed c, fixed coupling constants — an assumption that is not independently verified at early-universe or extreme field conditions. Z-pinch plasma environments, operating at stellar scale and above, generate temperature and density conditions sufficient for nuclear fusion. We present a conjecture that galactic-scale z-pinch plasma environments, operating under Machian variable mass conditions, generate sufficient temperature, density, and modified nuclear physics to produce light element abundances through plasma nucleosynthesis. Unlike Big Bang Nucleosynthesis, which posits a single primordial event, z-pinch plasma nucleosynthesis is an ongoing process operating continuously throughout cosmic history wherever plasma structures of sufficient scale exist. This conjecture is examined against known physics and is not falsified. A quantitative nuclear reaction network calculation under field-modified mass conditions is identified as the required test.
