Hi John-Erik,
Thanks for visiting my blog. I am glad you found the ideas interesting. And I am first to say they are not agreed upon reality. Experiments need to be made and others will need to see the usefulness of this new type of graviton before it becomes accepted.
To answer your question: There is gravity between Mercury and the Sun. I postulate that this gravity is composed of many gravitons connecting Mercury and the Sun. These many gravitons are what I call a graviton bundle and it is a "wire bundle" that is in a straight line between Mercury and the Sun. I make (a reasonable ?) calculation for the mass of this wire bundle (which will be very difficult to detect because of its long wavelength). I make another reasonable proposal that this wire bundle (graviton bundle) follows Mercury about the sun because Mercury in its orbit is always attracted by the Sun.
Two more assumptions:
1. The mass of this graviton bundle is uniformly distributed along the length of the bundle.
2. For the purpose of calculating the precession of Mercury (an angular momentum problem) I assume that the center of mass of the graviton bundle is in the middle of the bundle. Go to my web site to see the angular momentum calculation of Mercury's precession (just classical physics).
I tried to put that bunch of words above into the diagram I included in the essay. My fault for not including more words.
I remember your essay, and I believe this essay addresses some of the problems you pointed out. What I have not explicitly pointed out is that the network of gravitons that connects all the mass in the universe is "the ether" and it is this ether that supports the transmission of light. This ether is centered on the observer because the observer always brings their mass distribution with them (another diagram in my essay). And in a very interesting way the observer becomes the center of the universe. In other words Michelson-Morley did not have a chance of measuring a speed of light with respect to the ether because the light moves on the graviton network ether which is attached to the observer.
Did I just make Einstein wrong? No, I just explained why the speed of light is constant and independent of relative motion. Mass curves space-time and the distribution of mass is with respect to the observer.
And yes, all speculative stuff .....but perhaps better that the craziness that passes for current science?
Thanks very much for responding and giving me the chance to explain.
