Who is the father of astrophysics?
The term “father of astrophysics” is often attributed to Sir Arthur Stanley Eddington. Eddington, a British astrophysicist, made significant contributions to the field in the early 20th century. He is best known for his work on stellar structure and evolution, as well as his experimental confirmation of Albert Einstein’s theory of general relativity during a solar eclipse in 1919. Eddington’s research and writings played a crucial role in establishing astrophysics as a distinct branch of science, bridging the gap between astronomy and physics. While Eddington is widely recognized for his foundational contributions, it is important to note that astrophysics emerged as a field through the collective efforts of many scientists over time.
