In this case since light bending around the Sun would be very close to the Sun then since close to the Sun it is not a very good vacuum then light may slow down. Would this effect have to be taken into account in the calculations?

Photons must always travel at C, the reason C is talked about being the speed of light in a vacuum is that in a vacuum it is unimpeded. When photons move through another material they can appear to slow down (refractive index) but what actually happens is that their journey effectively increases. A photons slowing down is not so much them slowing below C, just that it takes them longer to travel the same distance (on a macro level; to us) whereas on an atomic level, light actually has to move a lit further to get through that medium due to molecular density and structure.

His 2nd only post is a link to the same thing in the middle of another unrelated thread
How about we delete this thread and remove him from ISS

The OP may never come back but it opens up for "interesting" conversation if nothing else
