Dear PicoPhysicist Sri Vijay
I appreciate your having closely read my fqxi essay - you are the only one who has answered all nine questions posed therin! Please forgive this hasty reply, but for the moment I will list below just your statements that I unequivecally agree on:
Q3 ..."Presence of matter increases space density and apparent reduction in speed of light." Yes.
Q4 "For gravitation force to exist a space density gradient is a pre-requisite. Greater is the gradient; greater is deviation of light towards higher density (lower radius of curvature)." Yes.
Q5 "Yes, it creates a disturbance in space it traverses ... The disturbance propagates with the photon, and appears as a pulse." Yes (omitting for the moment reference to K energy which I do not yet understand.
Q.8 "Dielectric Ether?" Yes.
Respectfully
Vladimir
