Can the differential in the speed of time between the far side and the near side of a Photon in relation to a large mass explain the bending of light?
"re-phrased to make it clearer or more precise"
Unfortunately I can only explain things in very simple layman's terms. These are things I have thought out with only elementary understanding of the relativity theory.
I imagine a dimensional photon passing by a dense mass whereby the near side of the photon travels at a slower timespeed than the far side of the photon. This has the effect of making the photon path bend towards the dense mass i.e. lensing effect.
I imagine the same thing happening as light enters a transparent medium. As one side 'hits' the medium it slows down while the other side rushes on, again causing it to bend it's path. This effect is larger with relatively higher frequencies with the separation of color frequencies as a result.
