Whose idea explained why the Sun shines for billions of years?
Quick Answer
Arthur Eddington’s. He proposed that nuclear fusion powers the Sun and other stars.
The Full Story
Arthur Eddington argued in the early 20th century that the Sun’s energy must come from nuclear processes rather than chemical burning or gravitational contraction. His reasoning helped open the path to stellar astrophysics. Later work showed that hydrogen fusion in the Sun’s core powers sunlight and gives the Sun a lifespan measured in billions of years. Eddington’s insight was crucial for understanding how stars shine.
