Q: First, I would never say that a theory has been proven. There may be a lot of evidence that supports a theory, and as a result it may no longer be on the list of theories that are being challenged, but theories are always theories and should always be open to adjustment by new evidence. A good theory is just a collection of hypothesis, experiments and deductions that survives repeated challenge and can therefore be used to predict untested outcomes.\nNow to your question (sorry for the tangent)... I think that most physicists consider Arthur Eddington's observations of the bending of light during the 1919 solar eclipse as the first solid evidence to support Einstein's theory of General Relativity. Einstein's theory predicted that gravitational fields would bend light, and Eddington's measurements supported that prediction, thus making it the first empirical data to support the theory.
