Illustrated London News 1919 - Eddington Experiment




The original caption for the graphical explanation of the experiment read as follows: The results obtained by the British expeditions to observe the total eclipse of the sun last May verified Professor Einstein's theory that light is subject to gravitation. Writing in our issue of November 15 [1919], Dr. A.C. Crommelin, one of the British observers, said: "The eclipse was specially favourable for the purpose, there being no fewer than twelve fairly bright stars near the limb of the sun. The process of observation consisted in taking photographs of these stars during totality, and comparing them with other plates of the same region taken when the sun was not in the neighbourhood. Then if the starlight is bent by the sun's attraction, the stars on the eclipse plates would seem to be pushed outward compared with those on the other plates…. The second Sobral camera and the one used at Principe agree in supporting Einstein's theory…. It is of profound philosophical interest. Straight lines in Einstein’s space cannot exist; they are parts of gigantic curves." From the Illustrated London News of November 22, 1919.
