So then, I guess it would further complicate matters if I mentioned that Gravity is a function of Mass, and that it too can influence the speed of light, hence the "gravitational lensing" of light bending around a Black Hole... smiley - weird

Yes, Peet, it would smiley - tongueout Happily we don't have any black holes in the immediate vicinity (not in this solar system anyway... or, at least, not that we've noticed smiley - winkeye) and so we can continue to lie about that on most levels smiley - smiley

Err, no. Gravity does not alter the speed of light. To an outside observer the velocity of the light lensing round a massive object is certainly altered, but from each photon's perspective it is travelling at a resolute c in the same direction it set out in. Spacetime bends to accommodate both perspectives.
