But in the case of gravity, you make a very simple geometrical argument that in no way refers to the structure of the force. Why is the geometry different in the two cases?

[Southack]

I don't know that the geometry *IS* different between electromagnetism and Gravity.

But I haven't been able to find a model as large as our Sun and Earth re: Gravity for the electromagnetism argument one way or the other.

You keep trying to put the burden of proving or disproving the analogy of Electromagnetism and Gravity on me, yet it is your argument, not mine, that they must be the same.

And you may very well be correct, but I see no reason why I should be compelled to show it one way or the other.
