    Because the baryon-to-photon ratio $\eta_{10}$ is in some doubt, we drop nucleosynthetic constraints on
the primordial abundances of light elements and consider the possibility that the baryon density is much larger than the critical density. We find that the baryon density is constrained to be $\Omega_b h^2 \leq 0.02$ at 95% confidence level. This bound is independent of the baryon-to-photon ratio $\
