There is a large variation in the observational results of VLBI, the Very long baseline interferometry techniques used all over the world, in the field of Radio astronomical observations. This variation is clearly visible when the when the solar gravitational deflection angle is plotted against Solar Elongation angle. Why such variation comes between different measurements? General Relativity predicts only one angle, not any variation is possible…………..
Can someone please give an explanation……
The explanation could be that the solar sunspots have an extra gravitational effect, see:
ReplyDeleteChanging sunspot distribution is assumed to be the origin of different forms of Solar gravitational lensing, found in different experiments.

Thank you LeoVuyk for your question / comments on my post. I am sorry for the late in replying you, I did not check my blog recently. You say, sunspots change the solar gravitation, then the observations show some times direction of bending changes in VLBI experiments. Why the direction of bending will of the light ray will change, if the reason is only sunspot activity?
DeleteYou will have to consider the Gravitation effect of other planets and the Universe as a whole on this light ray.
