Steve,
Relativity treats gravity as a collapse of space and coherence is a collapse of the wave. So rather than there being this force of quantum gravity, possibly it emerges from all the waves/particles/forces interacting and thus measuring each other. Then it appears as this elemental composite effect, starting off slowly, with the redshift of intergalactic light, to the ultimate collapse of black holes.
Gravity does curve light and there seems a flow from the convex curvature of intergalactic space, to the concave curvature of galactic space. It seems they are two sides of the same process, where the energy of light is constantly pushing out, yet its interaction pulls it inward.
I realize this isn't being expressed in the most scientific terms, but there does seem to be a grand cycle there, of which we only grasp fragments of and then assemble in the most happenstance ways, then have to propose enormous new forces of nature to fill the gaps and ties the loose ends.
Look at the construction of galaxies, with these metal poor, yet very old satellite galaxies on the edges and presumably that is where most of the dark matter is. Yet if there is some collapse/gravitational curvature going on, it would explain why these outer edges are held so tight to the core of the galaxy and why it bends light passing through. So galaxies would be grand vortices, extending far out beyond their visible fringes, as light radiating out and falling in as cosmic rays? Just as there are enormous bubbles out the poles, with the occasional jet shooting across the universe.
I did post a [link:nautil.us/issue/15/turbulence/do-we-have-the-big-bang-theory-all-wrong]link previously[/link}, about photons interacting:
"These result from a kind of turbulent interaction of photons with other photons--an interaction which is usually impossible, but is enabled by the mediation of charged particles inside the solar wind.
In 2009 Fahr says he began to realize that the vacuum of space itself has a kind of remote kinship to a plasma. After all, modern physics describes the vacuum as frothy with virtual electric charges blipping into existence only to annihilate and blip back out again. Typically, though not always, these virtual particles are electrons and their antimatter counterparts positrons. So Fahr wondered: If the vacuum is an electron-positron plasma, then why wouldn't it also enable the same photon-photon interactions that occur inside the solar wind?
If this were happening, then empty space itself could be the source of the microwave background. The photons of starlight that have been streaming through the universe over millions and billions of years interact with each other over time, gradually achieving a kind of thermal equilibrium, and translating hot point-sources of starlight into a dull all-sky glow. "It's a very slow process which is operating," says Fahr. "However, assuming you have time enough, then the diffusion is bringing you from stellar emissions to background emissions.""
Do we really know all there is to know about light?
