Sir Arthur Eddington

Sir Arthur Eddington was a pioneering British astrophysicist known for his work in stellar astrophysics in the early 20th century. He provided key insights into the internal structure of stars, particularly how they generate energy through nuclear fusion, where hydrogen atoms combine to form helium. Eddington also played a significant role in popularizing Einstein's theory of General Relativity, demonstrating its implications for the study of the cosmos. His contributions helped establish astrophysics as a scientific discipline, bridging theoretical concepts with observational data, and influencing our understanding of stellar evolution and the life cycle of stars.
