What did Eddington's 1919 eclipse expedition confirm?
Evolution theory
Heliocentrism
General relativity
Quantum theory
Answer
The answer is general relativity. General relativity is a theory of gravity that describes the universe at its largest scales. It explains the observed bending of light around massive objects, such as stars and galaxies. This bending of light was first observed during the 1919 solar eclipse expedition led by British astronomer Arthur Eddington. The expedition's observations confirmed general relativity and revolutionized our understanding of the cosmos.
