Paper 7 — BBN and the c³ Hypothesis
Applies the early IO cosmology to Big Bang nucleosynthesis and finds a mixed result: helium is viable, lithium is improved relative to ΛCDM, but deuterium is overproduced because of the low baryon-to-photon ratio. The paper also frames the resulting combined tension and introduces the c³ hypothesis as part of the early-stage response.
