It is my perception

that: a body of relativity's density, or time dialation strength can be measured by it's light particle/wave ratio.

in other words:

we can see a star that exists outside of our galaxie, and we know that star light bends around galxies like ours, therefore a "membrane" of light must exist extending from one side of the galaxie to the other, and that this desity of light is different than the light membrane sphere outside of, and flowing around, our galaxie. We percieve strings, or rays of light that are directly inline with our eyes and telescopes.

and when we look at these light rays up close we see the particles that make up the membranes.

Not quite sure what you're asking/stating here.

 

It is often useful to represent light as spherical waves travelling out from their origin, is this what you're getting at?
