摘要: The determination of the global cosmological parameters is discussed. It argued that Hubble constant likely to lie between 75 and 100km s-1Mpc-1, a low value (H 0 ≈ 50km s-1Mpc-1) quite unlikely. also shown current observational evidence supports density (typically Ω 0.1) universe. Combining these with accepted for age universe, it concluded sizable amount probably necessary. We discuss same conclusion inferred from number count faint galaxies.
