This analysis addresses the missing baryon problem and the accuracy of baryon census from Big Bang Nucleosynthesis, suggesting possible knowledge gaps.
To continue… we had been discussing the baryon content of the universe, and the missing baryon problem. The problem exists because of a mismatch between the census of baryons locally and the density of baryons estimated from Big Bang Nucleosynthesis (BBN). How well do we know the latter? Either extremely well, or perhaps not so well, … Continue reading What is the Baryon Density, Anyway?
