On May 29^th 1919 there was a solar eclipse, seen a few degrees below the equator, and two British expedidions were sent to take photographs of stars in the solar corona, to be compared with pictures taken when the sun did not intervene. The fact that the light from the star moved slightly in position was taken as proof that gravity moved the light. Asked what he would have said if the experiment had not proved positive, Einstein had the gall to say “In that case I’d have to feel sorry for God, because the theory is correct!”

In fact the light was bent because of the increased density of dark matter around the sun, and not by a force called gravity.
