Gravity Probe B. Frame dragging is not just refraction. There is some controversy here too, I dare say...
Probe B gave a null-result: No frame-dragging.
But by assuming that the gyroscopes are electric charged, they could find a way
to fit the curve that they wanted.
For now I have only seen flawed evidence of space-bending and light-bending.
Clock-speeds do seem to change. I personally think that we need to scrap
general relativity and replace it with something else that does match all observations.
A good video on this is:

They demonstrate effect of gravity on mass, not the bending of light.
The plasma around the sun is much more dense and expands much more than mainstream wants to
admit. See Robitaille's channel for details.
It seems to me that there is not much empty space around that sun.
Lets add more "evidence":
The LIGO is discussed in another thread, and it is now clear that the instrument is a receiver of
low frequency electromagnetic waves. They can build antennas in the same way.
We also have the Apsidal precession. Which is hard to explain with Newton's gravity only.
General relativity explains this by having some extra force, which kind of matches with the precessing of Mercury.
If mercury is electrically attracted by the sun, it might also add some force. So this can also cause precessing.
This still needs more research, but it affects mass not light.
Conclusion
I have not found any experiment consistently proving the bending of light due to gravity.
Gravity discussion
For me gravity is directly related with the Wave Nature of Matter.
See:
On Gravity and the Uncertainty Principle.
So instead of being in conflict with QM, the most accurate theory ever, gravity is actually caused by QM.
This model still needs improvements to match with the clock-change observations.
It is just sad that this important discussion is under Thornhill's gravity model,
because I don't agree with that either.
People seem to forget that you can't proof that you are right,
by proving that others are wrong.
You can only proof you are right by showing that your model
can be tested and matches with all observations.
So: ALL listed gravity models are wrong, including mine.
