James Peebles is a Canadian astrophysicist known for his groundbreaking work in understanding the universe's structure and history. He contributed significantly to cosmology, the study of the cosmos, including theories about the Big Bang and the cosmic microwave background radiation, which is the afterglow of the early universe. By applying physics to explain the formation of galaxies and large-scale structures in the universe, his research has helped shape our understanding of dark matter and dark energy. In 2019, he was awarded the Nobel Prize in Physics for his vital contributions to the field, influencing both theoretical and observational astronomy.
