The problem was that I even provided a derivation of the fact that the speed of light varies in the presence of gravity, It was ignored. Sheesh!

You seem to be missing the fact that the speed of light, in meters per second, is constant

**by definition**. That which is

**defined **as a constant can't possibly vary, regardless of gravity. The definitions of meter, second and speed of light are inexorably tied to one another.

Those definitions are also tied to a particular electromagnetic emission from a cesium atom. The definitions make no distinction about where the cesium atom is. It can be in the middle of a cosmic void or at the event horizon of a black hole; either way its wavelength and frequency in meters and seconds are exactly the same

**by definition**.

If you want to invent new units of distance and time which yield a variable speed of light, you may do so. I'd try to do it myself, but I am not a mathematician, so I'd be doomed to fail. Actually, I would prefer units of distance and time which represent a flat space-time continuum, even in the vicinity of a black hole. This would not alter the fact that the space-time continuum represented by a 4D grid of meters and seconds

**is** warped. It would just give you a different way to look at that warp.
