Well... In case you didn't already know, let me preface my comment with a qualifier; I'm a theoretical physicist.
Here is the essence of the gravitational section of a unified theory that I have been working on for well over 30 years:
There is no such thing as a "graviton particle." Gravity is the result of resisting movement through the fabric (or, aether, if you will) of spacetime. The more mass that is located in a point of space, the more it resists movement through time. This creates a multidimensional gravity well in the fabric of spacetime.
Of course, there exists another multidimensional stream which is "pushing" (as it were) the mass through spacetime. But, I don't wish to get into that as I have yet to publish that paper...
"Nineteenth-century physicists believed light waves must move through an "aether"—a medium that permeates all of space, allowing light to propagate just as sound waves move through air. However, a series experiments by Michelson and Morley failed to find any evidence that Earth moves through an aether. Einstein’s theory of relativity was the final nail in the aether’s coffin, because it explained that light moves through a vacuum. "
Yeah, this is where modern quantum physics started to go wrong. They assumed that this "aether" existed in phase with our own dimension and neglected to take into account its multidimensional aspects. Had they avoided that mistake... Well, the mind boggles at the potential discoveries we would be enjoying right now...
Anyway, if you like theoretical physics, here is a link to "Einstein-Aether Theory" that Jacobson co-authored:

May I ask a dumb question? What if the sun, with all its mass, were shaped like a cube, instead of a sphere. What would orbits look like? What would happen at the interfaces/sides of the cubes as a planet transit-ed that point?
parsy, who has been trying to keep the shortest distance stuff he read in Bertrand Russells(?) book on relativity. (Dang I wish I had my books with me!!!)
