We understand the universe is expanding. But do we understand the physics of it? This prediction is about the future of cosmological principle; how space expansion can be thought of as redshifting light.
We treat expanding space like motion. There is a space-stretch inbetween the galaxies that makes the universe as a whole larger.
It is also seen as galaxies moving away from each other in space. And this is what we do with the "Doppler shift" or the redshift to light. We use "motion" redshift to calculate the distance of a galaxy. This is Hubble's law. But there is more to it.
I believe that the space-stretch I talk about is equivalent to the motion of galaxies away from each other. The space-stretch inbetween the galaxies is identical to their actual motion through space.
What I am proposing is that the space-stretch can be seen as resposible for the redshift to light. In other words stretching space also stretches out the light that is traversing intergalactic space. So the two phenomonon space stretching light and the Doppler shift to light due to motion appear to be equivalent. And in physics we can use the term "operational" to describe this fact. It can be explained in two ways. The redshift to light is thus an operational phenomenon.
The space-stretch stretches light.
And by the way the universal expansion is now known to be accelerating. In other words the rate of the stretch is getting faster.
Sorry to say this is old information. It has been pointed out to me that the space-light stretch is already cosmological theory.
There is one thing that may have not been said: The redshift to light due to the space-stretch is equivalent to the Doppler shift. One is motion of matter and the other can be seen as motion of space carrying the matter with it. But they have to be equivalent for us to know where the galaxeis are in the universe as a whole. Otherwise cosmology would look very strange!

If you take the space-stretch and Einstein's Closed Universe cosmology seriously it can be seen that the stretch inbetween the galaxies is also the expansion of an hypersphere.
The universe according to Einstein can be seen as the surface of an expanding hypersphere. From our point of view we see it as the space inbetween the galaxies stretching but it really translates into a cosmology first pointed out by Einstein - an expanding 4Sphere - Einstein's finite but unbounded universe. It has no boundaries.
