Ralph Alpher

Ralph Alpher was an American physicist known for his significant contributions to cosmology, particularly in understanding the Big Bang theory. In the early 1940s, he, along with George Gamow and Robert Herman, developed a theoretical framework predicting the existence of cosmic microwave background radiation—an afterglow from the Big Bang. Their work laid the groundwork for modern cosmology, helping to explain how the universe began and evolved. Alpher's research provided key insights into the composition of the early universe, influencing our understanding of its fundamental structure and the formation of elements.
