The Standard Model of Cosmology...and Open Questions, or Why Jim Peebles was Awarded Half of the 2019 Physics Nobel Prize

Experiments and observations over the last two decades have provided strong support for a standard model of cosmology that describes the evolution of the universe from an early epoch of inflation to the complex hierarchy of structure seen today. I review the basic physics, astronomy, and history of ideas (many developed by Jim Peebles) on which this model is based. I describe the data which persuade cosmologists that (as yet not directly detected) dark energy and dark matter are by far the main components of the energy budget of the universe. I conclude with a list of open cosmological questions.
