### No Crisis for Big Bang Nucleosynthesis

Abstract:

Contrary to a recent claim, the inferred primordial abundances of the light elements are quite consistent with the expectations from standard big bang nucleosynthesis when attention is restricted to direct observations rather than results from chemical evolution models. The number of light neutrino (or equivalent particle) species ($N_\nu$) can be as high as 4.53 if the nucleon-to-photon ratio ($\eta$) is at its lower limit of $1.65 \times 10^{-10}$, as constrained by the upper bound on the d...
