The Modern Origins Story: From the Big Bang to Habitable Planets

The scientific understanding of our origins began in earnest with Copernicus, Galileo, Darwin, and others, and has since evolved into a rich, detailed, and well-tested model. Direct observations of the infant universe now show that it was remarkably smooth compared to what we see around us today, with only tiny differences in its properties from one part to another. By contrast, in the present universe there are enormous differences in the properties of matter from one part to another: some regions host planets, stars, and galaxies (and even humans!) while others do not. In this talk, Prof. Quataert will describe how the universe evolved from its smooth beginnings to its current state, emphasizing how gravity reigns supreme and builds up the planets, stars, and galaxies required for biological evolution to proceed.

Speaker: Eliot Quataert, UC Berkeley
