Starlight bent by the Sun's Attraction: The Einstein Theory
This diagram drawn by W. B. Robinson illustrates Professor Einstein's Theory that light is subject to gravitation. The drawing was based on British observers' photographs at the eclipse of the sun on the 28-29th May 1919. Photographs of stars were taken during the total eclipse, which were then compared to other plates of the same region taken when the sun was not in the neighbourhood. Comparing the two plates, the stars on the eclipse plates seemed to be pushed outwards, thus starlight was found to be bent by the sun's attraction. Dr A. C. Crommelin, a British observer working on the project, wrote that 'straight lines in Einstein's space cannot exist; they are parts of gigantic curves.'
