摘要

我所强调的宇宙学参数包括宇宙年龄t0t_0、哈勃参数H0100hH_0 \equiv 100 h km s1^{-1} Mpc1^{-1}、平均物质密度Ωm\Omega_m、重子物质密度Ωb\Omega_b、中微子密度Ων\Omega_\nu以及宇宙学常数ΩΛ\Omega_\Lambda。当前证据倾向于t013t_0 \approx 13 Gyr,h0.65h \approx 0.65Ωm0.4±0.1\Omega_m \approx 0.4\pm0.1Ωb=0.02h2\Omega_b = 0.02h^{-2}0.001<Ων<0.10.001 < \Omega_\nu < 0.1,以及ΩΛ0.7\Omega_\Lambda \approx 0.7
