Well, at least its going to require some reworking...

With regards to the red shift,The anti expansion guy I heard was hanging his on "tired light". Basically photons bleed off energy as they travel through space time and slow down.
First, I am the wrong guy to ask/try to answer, but this is the internet so whatever. Feel free to discard the below comment though.FTACo88-FDT24dad said:Duncan Idaho said:

I am no physicist, far from it, but isn't the speed of light pretty much the one thing we know doesn't change?

Few things. The speed of light doesn't change. It's energy is directly related to it's frequency, so higher frequency light (xrays, UV, gamma) have higher energy than lower frequency (infrared, microwave, radio). As far as I know, there is no way to directly increase or decrease the energy of a specific light wave. You can absorb a photon and re-emit it with a higher or lower energy, but I don't think you can directly affect it with some sort of field to increase or decrease the frequency. So the idea of light just losing energy due to travel in a vaccuum doesn't have any precedent of which I am aware.nortex97 said:First, I am the wrong guy to ask/try to answer, but this is the internet so whatever.

Yes, this constant is a thing and people have been trying to prove otherwise for well over a century to no effect. How photons can get away with not interacting with magnetic fields (they aren't charged), and whether light actually can/may/could slow down outside of space (if space time is stretched) is tough to comprehend. We have tried it in the lab.
