Speed of light
[edit]Is there a reference for the Einstein / Speed of light reference? Benjicohn (talk) 18:48, 4 June 2009 (UTC)
- The statement in the article is plainly incorrect. The 1922 eclipse was used to confirm Eddington's 1919 findings that supported Einstein's general relativity theory. (See tests of general relativity.) The speed of light had been reasonably well established by that time. Regards, RJH (talk) 16:37, 31 March 2012 (UTC)
I agree. The observation in 1922 was in reference to the general relativity theory, not the speed of light. I cannot find the specific references, but certainly beta virginis was in the near vicinity of the eclipse path here, and could well have been one of the stars used in the observation. But again, this was in reference to the general theory of general relativity, not the speed of light.

I too was jarred by the claim this star was involved (as well as the assertion that the the speed of light was measured ... not ... and that Einstein measured it ... not) and removed it. Maybe someone misunderstood something they read, but with one certain and one probable error, the statement doesn't stand without citation. Here's some information about the 1922 Wallal/Wollal eclipse observations (by astronomers of Australia and of Lick Observatory). It was announced in May 1923 that their observations did indeed confirm Eddington's inconclusive measurements of light 'bending' during the Solar eclipse of May 29, 1919. Maybe this image can help determine if the B. Virginis assertion is correct. This page includes a couple of possibly helpful references, and states that "it was the measurements from these plates that finally led to H. Spencer Jones of Greenwich Observatory announcing in May 1923.... Twang (talk) 01:25, 8 November 2015 (UTC)
