Abstract:  “…the Universe was radiation dominated during Big Bang Nucleosynthesis (BBN)…”

Introduction: “Yet there remains a gap in our understanding of cosmic history – a gap that spans the first few seconds. How, during that brief time interval, did the energy density of the universe come to be dominated by relativistic particles?”
