Originally I asked on another thread whether the GR effects on light can be described as light passing through a medium of varying density- so exerting its effects by refraction.
A.T. kindly posted the following links:

However his the post was erased(I can only assume for necroposting as Nature Photonics is peer reviewed).
The links seem to confirm my original suspicions that the gravitational effect on light is caused by refraction, and A.T. suggested this medium would be varying densities of "space-proper time".
Does anyone have issues with this explanation as it is much simpler to understand and would be a useful teaching aid if it were correct?
