Kaptain K: If the energy manifests itself at the speed of light in all directions, then the implication, of course, is that a star's own gravity is decreasing, and that the gravity is being "released" in an ever-expanding speed-of-light sphere around the star.

Can this "store" of progressively weakening, invisible gravity from an extinguished or dying star in any way account for the dark matter that appears to be inexplicably tugging at the rest of the universe?
