James Peebles was born in St. Boniface, near Winnipeg, Canada, where his father worked in the grain business. After attending the University of Manitoba, he continued his studies at Princeton University in the United States, receiving his doctorate there in 1962. He remained at Princeton University where he is now Professor Emeritus of Science.
Fundamental questions about the universe’s structure and history have always fascinated human beings. James Peebles’ theoretical framework, developed since the mid-1960s, is the basis of our contemporary ideas about the universe. The cosmic background radiation is a remaining trace of the formation of the universe. Using his theoretical tools and calculations, James Peebles was able to interpret these traces from the infancy of the universe and discover new physical processes. The results showed us a universe in which just five per cent of its content is known matter. The rest, 95 per cent, is unknown dark matter and dark energy.
