James Peebles

James Peebles is a Canadian scientist and the 2019 Nobel Prize in Physics winner that was born on April 25, 1935 in Winnipeg, Manitoba. At the time of receiving the 2019 Nobel Prize in physics Peebles affiliation was with Princeton University in Princeton, New Jersey. Notable research contributions to physics made by Peebles include his work on fundamental research on cosmic microwave background (CMB) radiation, dark matter, dark energy, inflation, nucleosynthesis, and the structure and formation of the universe. Peebles was also one of the first scientists to use and develop computer simulations to predict and study the cosmic structure of the universe.

In 1958 James Peebles received a bachelor of science degree from the University of Manitoba.

In 1962 James Peebles received a Ph.D from Princeton University under the supervision of Robert Dicke. Peebles worked with Dicke's research team towards developing theoretical predictions of how the universe works using observed data. The team is well known for working on the expanding universe theory which predicts the earlier universe was hotter, smaller, and denser in the past, and can be proved with observable radiation called the cosmic microwave background.
