The Big Bang and the Cosmic Microwave Background
This presentation starts from the discovery of cosmological expansion by astronomer Edwin Hubble and then drills down on the fascinating cosmic microwave background (CMB), a baby picture of the universe that yields a surfeit of mysteries, among them the existence of mysterious dark matter and dark energy components in the universe. Grin discusses the fascinating history and physics of the CMB, the amusing story of its experimental detection, and the fascinating light it may ultimately shed on the first millionth of a billionth of a billionth of a billionth of a second.
