Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Take a look at the last paragraph in this the document at this link http://www.mathpages.com/rr/s6-03/6-03.htmBasically you can calculate the effect of both refraction (with some assumptions about the composition of the "atmosphere" of the sun and you can calculate the bending due to general relativistic effectds.&nbsp; Those two combined effects can then be compared with experimental data.&nbsp; <br />Posted by DrRocket</DIV><br /><br /><p>The way I see it between the "Ouija board" effect, and a possible miscalculation of the composition of the sun&lsquo;s atmosphere, 100% of General Relativity&rsquo;s gravitational bending of light could be explained away as refraction. </p>
