Since the universe is in stable orbit about its own center of gravity, its age is an indeterminant at this time. This means that ordinary electromagnetic waves have had perhaps 100s of billions of years to wave disperse down to the Fundamental Resonant Frequency of the taut-elastic aether fabric.

E-M waves have been shown by many experiments, including photovoltaics and lasers, to have kinetic energy. That is, they have PUSH, upon impact with a body of matter. So now we have them bouncing off the periphery of a finite ball of universal aether, an coming back at us from all directions. The periphery is as the periphery of a raindrop, and our ball of aether is adrift in the Greater Void.

Then any two bodies of matter in the universe shade each other from these wave dispersed e-m waves, which I call power Waves, because they supply the energy for gravity force and internal heating of celestial bodies, along with other necessary services, like igniting proto-stars.

Where the two bodies are spherical, the mutaul shading drops off approximately as the square of the distance, simply because of fresh Power Waves sneaking around the bodies as they are experimentally positioned farther and farther apart. I say it is actually a trig function.

BUT secondly, the shading also throws a Permanent Shadow right across the universe. And this function eliminates the need for the undiscovered Dark Matter.

The absorptive shading is at the quantum level, accumulating to the body level.
