Talk:Michelson–Gale–Pearson experiment

Expansion request
When was this experiment performed? Did the results agree with or disagree with the Michelson-Morley experiment? What is the currently accepted interpretation? -- Beland 20:07, 16 April 2006 (UTC)

Does anybody have any source for the claims in this article? —Preceding unsigned comment added by 87.6.150.215 (talk) 20:20, 3 September 2007 (UTC)

More needed
Could we get the sagnac equation that applies to this experiment and show how it predicts the result? The math done by Michaelson assumed an inertial frame and variant light speed and did so, so I believe there is onus on those supporting Relativity to show this. I have not seen this done anywhere by anyone, ever. Since the idea of this experiment being assumed to be an inertial frame is demonstrated to work, then applying that to relativity predicts a null result. We can simply always use the destination mirror as the FofR and delta t will be the same in both directions. On the other hand, we have Michaelson's math based on the idea of variant light speed predicting the observed results!

Normally sagnac applies to symmetric setups which rotate about the centre of the apparatus - this experiment is not even close to that. The last paragraph in this article works just as well for a fully entrained aether as it claims to for relativity also.

I cannot see how this experiment has the right to claim what it does about relativity or the fully entrained aether. Hosh1313 (talk) 06:07, 12 October 2011 (UTC)


 * That the Michelson-Gale experiment measures the Sagnac effect, is well known - see the references to Anderson or Stedman, and many other sources. This is so obvious, that I can hardly believe that someone can't accept this. --D.H (talk) 14:27, 12 October 2011 (UTC)

I would point out to you that the math you have now displayed on the page, as derived by Michelson himself, is based on 2 assumptions - variant lightspeed AND an inertial frame of reference. And these predict the result. If we now apply the assumption of the inertial frame and consider SR, then we see that SR predicts a null result since the speed is always the same to the destination mirror as is the distance. In none of the references provided here, or anywhere else that I know of, is specific math for SR provided that predicts the measured result. As far as I'm concerned, this experiment disproves SR until someone produces the SR specific equation and shows that it predicts the result. Hosh1313 (talk) 03:51, 14 October 2011 (UTC)
