A golden age for precision observational cosmology

Yin-Zhe Ma gave a nice physics colloquium at UQ last week, A Golden Age for Cosmology
I learnt a lot. Too often, colloquia are too specialised and technical for a general audience.
There are three pillars of experimental evidence for the Big Bang model: Hubble expansion of the universe, relative abundance of light nuclei due to nucleosynthesis in the first few minutes, and the Cosmic Microwave Background.
Ma showed Hubble's original data from 1929 for redshift versus distance of galaxies. There.
