[This book may be used to popularize other things in the future, such as animals, pet plants, etc.] Observable cosmology relies on repeatable and verifiable measurements to simplify the universe into its space-time metric and energy components. Telescopes, satellites and large-scale sky surveys collect photons and particles in electromagnetic waves, neutrinos, gravitational waves and other channels. Using red shift, parallax, standard candlelight, gravitational lensing, galaxy distribution and cosmic microwave background anisotropy, the Hubble constant is determined to be about 70 km/s/Mpc, with baryonic matter accounting for 5%, cold dark matter 25%, and dark energy 70%. The data is fitted to the ΛCDM model, predicting the age of the universe to be 13.8 Billion years, and giving the history of inflation, accelerated expansion, and the formation of large-scale structures. In the future, larger samples, higher precision and multi-messenger joint observations will test the dark energy equation of state, neutrino mass and gravity theory, and continue to use evidence to revise mankind's objective description of the universe.
