In this lecture, James E. Peebles, Nobel Prize Laureate in Physics and Albert Einstein Professor Emeritus of Science at Princeton University, reviews the historical development of modern cosmology, from the first observational evidence of the universe’s expansion to the establishment of the standard cosmological model. He explains how observations of the cosmic microwave background, galaxy distributions, and other data have helped build a coherent and quantitative picture of the universe from its earliest moments to the present day. Peebles also reflects on the open questions that remain—such as the nature of dark matter and dark energy—and emphasizes the importance of curiosity and rigorous theoretical thinking in advancing our understanding of the cosmos.

This lecture, delivered in April 2015, is part of the astrophysics series ‘The Science of the Cosmos, the Science in the Cosmos’. This lecture series tackles the fundamental questions in contemporary astrophysics.The fourth edition considers the enigmatic nature of dark matter and the most recent attempts to detect it with large underground instruments, the expansion of the universe, as well as recent research with particle accelerators.
