John Turner (physicist)

John Turner is a physicist known for his work in cosmology, the study of the universe's origins and structure. He contributed to understanding the early universe, particularly through research on the cosmic microwave background—a faint radiation providing a snapshot of the universe shortly after the Big Bang. Turner has helped develop theories about how the universe expanded and evolved, and he has been involved in experiments and observations that test these ideas. His work helps scientists learn how the universe came to be and how it continues to change over time.
