Albert Einstein Professor of Science Emeritus at Princeton University

Thèmes de recherche

With Robert Dicke and others, he predicted the existence of the cosmic background radiation (previously predicted by Ralph Alpher and Robert Herman) and planned to seek it just before it was found by Arno Penzias and Robert Wilson. He has investigated characteristics of this radiation and how it may be used to constrain models of the universe. He has led statistical studies of clustering and superclustering of galaxies. He has calculated the universal abundances of helium and other light elements, demonstrating agreement between big bang theory and observation. He has provided evidence of the existence of large quantities of dark matter in the haloes of galaxies, and he continues to work on the origin of galaxies. Peebles was one of the first to resurrect Einstein's cosmological constant, suggesting it was needed in the 1980s.
